Perfect and safe contact protection

SCHLEICH test covers are a robust, durable investment for reducing operator hazards. Ergonomics and reliability are prioritized, thanks to the contact-safe covering of the devices under test.

The smooth-running test cover is made of shatterproof, transparent plastic and covers the device under test to allow visual observation or inspection during testing. Tests are only possible when the test cover is closed, and the closed state of the cover is continuously monitored by a dual-circuit safety limit switch. It complies with legal requirements and is safety-approved.

Closing the test cover starts the test sequence. Opening it during an ongoing test leads to an immediate cancel by the test device. The TEST VOLTAGE is switched off in the test device, and the device under test is discharged. The discharge process is monitored by the test device.

Via the optional interlock, the test cover remains locked:

until the complete discharge of the device under test
until the completion of a mechanical movement or rotation
in case of a negative test result (NOGO)

The test covers can be equipped with custom mechanical fixtures for your devices under test. These can be easily mounted on the base plate or interchangeable plates. Inside the cover are Connections for contacting the test leads. The connection cables to the test device are typically connected via safe plug connectors on the test device.

The complete insulation of the test space prevents voltage propagation to the outside. Operating personnel are optimally protected.

To protect sensitive products from electrostatic charge and discharge, test covers made of ESD materials are available at an additional cost.
