The automatic testing process
GLP2-BASIC the lightweightWindows® Embedded operating system. You always have a clear overview of all relevant test results. The clear display of the test sequence enables structured and highly efficient work.
In automatic mode, the tests are performed semi-automatically or fully automatically. The tests proceed step by step in a fully automated manner between all measurement terminals connected to the test object.
If, for example, the operator needs to manually scan individual measurement points on the test object using a probe, the process is interrupted and a notification message appears. This interruption lasts until the manual task has been completed. The test then continuesfullyautomatically. The test results are automatically evaluated and clearly displayed.
The test sequence can be modified simply by adding or removing test steps. This allows the test sequence to be optimally adapted to various requirements. Each individual test step can be configured separately using test parameters.
The comprehensive integrated user management system ensures that only authorized individuals can make these changes.

The input
To perform the test steps, simply select them. The test parameters can be easily modified, allowing the test procedure to be quickly and flexibly adapted to the specific test task. Each entry is immediately checked for validity.
The test steps are configured directly within the test sequence. A separate test plan editor is not required for this.
For each test parameter, clear explanations are available via an integrated help button and can be displayed with a single click.
The test parameters are clearly visible to all operators, but only authorized personnel may make changes.

Manual measurement
GLP2-BASIC you with access to all integrated test methods individually—as if you had a separate testing device for virtually every test method.
No test plan is required to use the unique manual mode. The operator simply selects the desired test method and starts the tester.
The most important measurement values are displayed in large digits. The other settings are also clearly displayed. This feature is unique. It is ideal for testing in the lab or at the repair station.




Manual mode
Select the desired test method and start the measurement. You can stop and resume the measurement at any time.
There is no comparison with threshold values. Instead, the measured values and the set test conditions are displayed continuously.
During the measurement, the test parameters can be adjusted via the touchscreen. This is a major advantage. As a result, your test specimen is continuously exposed to the test conditions. You can put it through its paces and subject it to stress for as long as you like.
Not only can test conditions such as test voltage and test current be adjusted, but the displayed actual values and their physical units can also be switched to suit the desired analysis.
The functional structure of the test device

SCHLEICH testing technology has proven itself tens of thousands of times in daily use. It is among the most reliable solutions on the market and impresses with high performance, excellent measurement accuracy and clear added value for industrial testing processes.
For time-saving contacting, all connections of the device under test can be conveniently connected via a contact adapter. The test instrument then performs all scheduled tests fully automatically and without manual intervention. This is made possible by the standard, SCHLEICH-typical automatic test method switching.
It is particularly economical to connect all test points of the device under test directly to the test instrument. The system then automatically tests all relevant combinations between the connection points. This significantly reduces the required cycle rate – and thus also the cost per test. The necessary switching operations are performed as standard using flexible and reliable switching matrices.
Test methods
Depending on the configuration of the test instrument, different test methods are integrated. Each of these test methods provides 2, 4, or more connections. These connections lead to the test method switching.
Automatic test method switching
Modular Test Point Expansion | Relay Matrices
Switching between test stations
For high production volumes, an additional testing device is often used if the cycle time of a single system is insufficient. However, if the actual testing time is shorter than the handling time, including connecting and disconnecting the test piece, dual or multiple stations offer a particularly efficient alternative.
While testing is underway at one test station, loading or unloading can occur simultaneously at the second station. To eliminate any potential electrical hazards for the operating personnel, the measuring leads of the inactive test station are reliably and safely disconnected. Additionally, the connections of the device under test are actively grounded.
Mechatronics | Script Control
Using the built-in scripting functions, additional PLC functionalities can be quickly and easily implemented directly within the test device. Similar to a traditional PLC, inputs can be read, outputs can be set, and logical operations can be created.
The economic advantage lies in the direct control of mechatronic processes by the testing device. For example, valves can be controlled, limit switches queried, measured values individually evaluated, or further process steps specifically influenced. This allows additional processes to be automatically integrated before, during, and after the actual test.
This unique flexibility makes the testing equipment ideal for customer-specific testing systems as well as for seamless integration into automated manufacturing processes.

Test Methods

Protective conductor resistance test
The protective conductor is tested using an electronically controlled, constant test current. The tester calculates the protective conductor resistance based on the voltage drop across the protective conductor and the current flowing through it. This resistance must not exceed the maximum resistance specified in the standards. Using a test probe (to be ordered separately), the operator scans the protective conductor connections to be tested one after another on the test object. The test is performed between the PE contact in the test socket and the test probe.
More information

Insulation Resistance Test
The insulation test is performed using an electronically controlled, constant test voltage. The tester calculates the insulation resistance based on the voltage drop across the insulation and the current flowing through it. This value must not fall below the minimum resistance specified in the standards. The insulation resistance can be measured both between all electrical conductors (Class I devices) and between the electrical conductors and insulated housing parts (Class II devices). The operator uses the test probe to scan the housing parts to be tested one after another. At the end of the test, the test object is always discharged.
More information

DC High-Voltage Test
The insulation test is performed using an electronically controlled, constant high voltage. During the test, the test current must not exceed a specified maximum value. If the current rises above the maximum value, the test is automatically terminated. At the end of the test, the test object is always discharged. More information

AC High-Voltage Test
The insulation test is performed using an electronically controlled, constant high voltage. During the test, the test current must not exceed a specified maximum value. If the current exceeds the maximum value, the test is automatically terminated. At the end of the test, the test object is always discharged. More information

Functional test
The functional test of your test object is performed at operating voltage based on the current consumption, the power factor (cos), and/or the power consumption of the test object. Target values and ± tolerances can be specified for each measured quantity. If the measured electrical value falls within the tolerance, the test result is OK. The test voltage for the functional test at 5 A is generated electronically within the test device.
The 5-A test is specifically designed for measuring very small currents. This allows for the measurement and evaluation of very low power levels, for example in LED lights. The test voltage for the 16 A functional test is not drawn directly from the test unit’s power supply line, but is fed in via a separate test voltage supply line on the back of the test unit. This allows different test voltage levels to be applied.
More information

Leakage current test
The leakage current test is performed during the functional test. The test verifies that the leakage current from the L+N conductors to PE (ground leakage current) or to insulated housing parts (housing leakage current) is not excessive. The leakage current must not exceed the maximum current specified in the standards. To test the enclosure leakage current, the operator uses the test probe to scan the enclosure parts to be tested one after another.
More information

Leakage Current Test “Alternative Method”
The leakage current test is not performed during the functional test. The test verifies that the leakage current from the L and N conductors to PE (ground leakage current) is not excessive. The leakage current must not exceed the maximum current specified in the standards. For the test, a low AC voltage is applied to the L+N terminals of the test object relative to PE. The current flowing during this test is extrapolated to the current that would flow at normal operating voltage.
More information
The Test Report
All test results can be printed on the modern standard report either immediately after the test or at a later time. The language of the report can be selected individually before it is generated. Reporting is performed in accordance with IEC 61934. The standard languages available are German, English, Chinese, Danish, French, Italian, Dutch, Polish, Portuguese, Swedish, Slovenian, Spanish, Czech, and Hungarian.
Printout on paper
Anyone GLP2-BASIC to the GLP2-BASIC ® 10 or 11-compatible printer. As in Windows® , simply click the printer icon and all measurement results will be printed automatically.
Create a PDF file
If desired, GLP2-BASIC generates GLP2-BASIC PDF file that is saved to a USB flash drive, the internal hard drive, or any network path. The file is saved automatically to the root directory of the USB flash drive. There is no need to “copy and paste” in Windows® .
Generating a CSV file (optional)
Optionally, GLP2-BASIC can also generate a CSV file GLP2-BASIC a test run. The file is saved to any network path. The data exported to the CSV file is fully configurable and can be customized to meet your needs.
The GLP2-BASIC

The GLP2 expansion with the technology package takes full advantage of the extensive capabilities of Windows® to the fullest. The display appears on an external touchscreen monitor, with the screen layout dynamically adapting to the monitor’s resolution. The user interface is even more intuitive and clearly organized than the standard version. A full-featured PC is used to enhance performance.
The proven measurement hardware and precise measurement technology are identical to those of the standard model. The technology package represents an upgrade in terms of usability.
Based on Windows®PC, the large touchscreen, and the resulting technical capabilities, the user interface is even more informative and user-friendly than before. Our engineers have incorporated all the modern features of Windows®operating system. The result is a clear and well-structured display with a professional look and feel.
In addition to the standard software’s features, a test plan revision function—including comprehensive test plan history management—has been integrated. New or modified test plans can be approved in accordance with the dual-control principle. Test plans are approved by a second person, not by the person who created them.
GLP2-BASIC Network
Test plans and test results can be stored locally or, alternatively, on a central network drive. This ensures a high level of data security and facilitates the seamless exchange of test plans between different testing systems.
Even in its basic configuration, the GLP2-BASIC network-ready. This feature provides the ideal platform for collecting, managing, analyzing, and distributing information.
With an optional technology package, GLP2-BASIC offers the ability to integrate into a complex enterprise environment and can be connected to ERP, PPS, MES, and CAQ systems. We offer proven, configurable solutions to meet these requirements.
network outage

Each testing device automatically saves local copies of the current server test plan database so that it can continue operating in the event of a network outage.

In the event of a network outage, the local test plans are used and the test results are saved locally on the test device.

Once the network connection is restored, the testing device automatically sends the test results back to the server, ensuring that the server database is up to date.
Comprehensive global network for test equipment with a technology package

The testing devices can be operated in network topologies of any complexity. You can install an unlimited number of testing devices at various company locations worldwide and connect them to the central network drive. Our experience in the global networking of testing devices gives you the assurance that you will maintain the same product quality regardless of the production location. Problems with revising test plans are now a thing of the past.
Of course, all tasks related to test plans, printing, labeling, and statistics can also be performed on the individual test devices. However, to avoid disrupting the production process, it makes sense to use separate workstations for these tasks in networked systems.
The editor&printer PC software can therefore be installed on various workstations.
Label templates can also be stored centrally on a network drive. The testing device then loads the appropriate template based on the test plan and prints the labels after the test. Storing the templates centrally on the network drive ensures that all connected testing devices always use the same label template.
If remote maintenance is necessary, we can temporarily connect to your network and access the specific test device directly. We can see the test device’s screen in real time. With your permission, we would also have access to the mouse and keyboard. These capabilities are ideal for providing expert support. Of course, remote maintenance is only possible with your authorization.
PC software editor and printer

Edit test plans
Test plans are often created directly on the testing device. Alternatively, test plans can be managed, edited, and saved on a PC using theeditor&printer software, which is included free of charge with the device. Creating test plans on a PC has the advantage of not disrupting ongoing production. Work can continue on the testing devices. The software interface on the PC is similar to that on the testing device. As a result, operation is virtually identical and therefore easy to learn.
The software is used in two modes:
- Data transfer via USB flash drive | Offline operation
- Data exchange via PC network | Online operation
Printing Test Results
The software makes it easy to create and print test reports. To do this, import the test results from a testing device, filter them according to the tests you want to print, and generate detailed, easy-to-read reports.
