The polarity (+/-) was reversed when I made a measurement using the resistance range. Is the instrument broken?
https://www.hioki.com/us-en/support/faq/detail/id_123
I have a question about an analog tester. The polarity (+/-) is reversed when performing measurements with the resistance range. Why is this? Wouldn’t this invite mistakes, for example when checking diode polarity?
