A couple of years ago I picked up an HP 427A voltmeter (FET "VTVM") on eBay then acquired the matching 5300 True RMS AC voltmeter from an SK. Forty years ago that was one high-dollar pair of bench buddies and they're as clean and good as new.
A few months ago I reconfigured the workbench and made a space for them. First exercise for the 427A was to check a resistor before using it. Tested bad. Tried another. Tested bad. Went through four resistors before I realized they were all bad by about the same amount.
Yeah, I was trying to read Ohms on the Volts scale.
We all have our moments.
