I need an analog panel mount voltmeter that can show a minus DC voltage range of approximately -500mV to -1500mV
I read however, that an analog voltmeter cannot display minus values. Is that correct?
If it is, can I just reverse the polarity of the connections to a say, 2 volt voltmeter?
Many thanks!
