They are available as single and combination testers. With regard to the integration of functions, high power density and miniaturization, Handheld testers are outstanding. This generation of testing devices by Schleich represents compact and precise testers. They are mainly used on site. Therefore, the test electronics are integrated into a sturdy aluminum case. Optional accessories such as transport cases and shoulder straps even improve the handling of the device. Except for the high-voltage test AC, the tester can also be used for EN60204 tests. Without the high-voltage test, it is possible to perform all necessary tests according to the Machine Guideline. Due to the internal data storage, test results do not have to be written down. Handheld PE/IR Handheld PE/IR/SLC/FCT Handheld PE/IR 2500V DC Possible combinations of test methods in a device Handheld testers also allow an increase of the test voltage at the insulation-resistance test to max. 2500V DC. This offers an interesting alternative to the high-voltage test with AC. 1800V ACeff correspond to approx. 2500V DC. The test object is connected via test socket. Using the test probe, the tests can be performed against this socket. Alternatively, the tester can be connected to the enclosure (PE feeding point) of the test object by connection cable. In this case, the tests are performed against this PE point. A special application is testing the lightning conductors at wind-power stations. To perform tests with currents below 10A, the PE-minimum-current monitoring can be turned off. With a reduced test current and a test lead in 4-wire confi guration with a length of 50m, it is possible to test resistances up to 15Ù. If a PC is available, you can use our Windows® software PrintCom to store the test results directly on the PC.
