Multifunctional testers for electrical safety function
Multifunction testers combine several test methods in one device. At SCHLEICH , integrated test method switching SCHLEICH always standard. This test sequence switches the various test methods in a test sequence to the required test connections.
Your advantage
You device under test need to connect the device under test once, and the multifunction device will automatically perform all the necessary test steps in sequence. This saves time, reduces errors, and makes the testing process more efficient.
Typical tests
- protective conductor resistance
- insulation resistance
- High voltage AC/DC
- continuity
- Resistance
- Leakage current
- Voltage, current, and power measurement
- FI/RCD tests ...
Key facts:
- Combination of multiple test methods in one device

Good to know:
Multifunction testers
Multifunction tester vs. single-function tester – what is the difference?
The key difference lies in the scope of testing and functionality.
Multifunction testers
- Ideal for applications where multiple test methods need to be combined in a single system.
- Typical combinations:
- high voltage test insulation test protective conductor test function test leakage current
- Ideal for:
- End-of-line test benches
- mass production
- Automation
- laboratories
- Advantages:
- Higher acquisition costs, but more economical than several individual test devices
- Central test sequence control and documentation (Frank: safety this text for safety as well)
- No external PLC
- Maximum efficiency through fast automated test sequences
- Integration of automatic test method switching
- Integration of automatic measuring path switching
- High flexibility
- More space-saving than multiple individual test devices
Individual test devices
- Ideal for applications where only one test method e.g., high voltage test) is required.
- Suitable for:
- Manual testing with test guns or test probes
- Automation
- laboratories
- Advantages:
- Low acquisition costs
- Easy to use
- Compact design
- Disadvantage:
- A test device is required for each of the various test methods.
