Safety rule: determine zero voltage! The voltage and continuity tester from Wiha is your ideal daily companion to easily check this prerequisite of the safety rule and to support you with the various requirements in your daily work. It allows voltage testing of an extensive range from 0.5 V to 1,000 V AC or 1,500 V DC. In addition, the voltage tester can be used for continuity testing, optical rotational field testing, single-pole testing, and automatic polarity detection. Plus, resistance measurements and frequency measurements can also be conducted. Thanks to a large digital LCD display with background illumination and an LED display, the measurement results are immediately readable. An additional signal sound indicates the current flow during the continuity check. The check can also be conveniently carried out on sockets with a single hand thanks to the integrated spacer. In addition, the voltage tester from Wiha has an integrated flashlight function, providing optimal illumination conditions even in poorly lit work environments. Simultaneous pressing of both buttons on both handles of the test tips allows the functional test of the FI protective switch by connecting a load. According to the measurement categories CAT III up to 1000 V and CAT IV up to 600 V, the voltage and continuity tester from Wiha offers maximum safety for working on building installation and directly on the sources of low-voltage installations.
