POWER SUPPLY vs. BATTERY
I finally picked up a large package of batteries , in order to do the test .
I powered up the meter , then went through the calibration procedure , then found a NOS 3 watt 100 ohm carbon resistor that was waiting to get put away .
It measured about 109.?? [ this was yesterday and did not write down the last digits ] and with the meter plugged in to the power supply , with batteries installed , I pulled the plug from the PS at the meter and no change to the reading , even at the the lowest number .
![Huh? ???](https://www.eevblog.com/forum/Smileys/default/huh.gif)
, plugged back in PS and again no change .
Again thanks for the video .
