Very nice tester I've had one for the last year or so But why doesn't it have an audible sound when it detects voltage Besides that I would highly recommend
Hi, I have one of these models, however when I’m actually using this to check voltage, there is no audible noise. I only hear anything when carrying out a continuity test. Does this sound correct? Thanks!
No it has a built in proving unit as he demonstrated ie self check function . It says on the box TIS 851 voltage and continuity tester with built in proving unit
@@Dog-whisperer7494 Unfortunately you're wrong. Possibly misleading advertising. A proving unit proves it works when voltage is present. This just proves all the lights work and there's continuiy in the leads. It does not prove it works with a voltage on it.
