It also offers continuity testing optical rotating field testing single-pole testing and automatic polarity detection. Measurement results can be conveniently read on the led display. An audible signal indicates current flow during continuity testing. Furthermore the integrated spacer allows convenient one-handed socket testing. The wiha voltage tester also offers optimal visibility even in low-light conditions thanks to its integrated flashlight function. Simultaneously pressing the buttons on both test probe holders allows you to test the residual current circuit breaker by connecting a load. Compliant with the measurement categories cat iii up to 1000 v and cat iv up to 600 v the wiha voltage and continuity tester ensures maximum safety when working on electrical installations in buildings as well as directly on energy sources for low-voltage installations.**
