Knowing my wife, very likely a freebe, from Temu. I do like the non contact voltage testing, the four stage testing makes it easier to work out which wire is line. It is a PEN tester, with many functions, and for the 'firewire' not to work the way the instructions seem to indicate it should work, does not distract from the other functions.
But today it seems we need a course in meter reading, I have a smart meter, press and hold the one button and one can then get so much info, but not the off peak rate, holding the other button for two seconds and then pressing the first button gives you off peak rate. One wonders why designed that way?
My first multi-meter I destroyed by selecting wrong range
meters have move on since then, even the latter meter
I could not read what today is shown on my PC
reading 245.7 volt would need a suppressed zero voltmeter. As to why one needs to know to four significant figures the voltage I don't know? I do have one old clamp-on which will measure frequency, used it to set up generators, but not used it much.
The idea of checking an ES lamp holder has centre pin to line, seems good, but I would simply unplug and use ohm range, so not really required. And I still have one of these
the use of which has alerted me of a borrowed neutral. Yes we could use the clamp on to see if any current flowing, but borrowed neutrals are rare, so one tends not to bother, and using the screwdriver function anyway so the added neon is a good safety feature.
