--- Quote from: KD0CAC John on December 05, 2012, 01:47:11 pm ---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 .??? , plugged back in PS and again no change . Again thanks for the video . --- End quote --- I was wondering if you would test a resistor 10 k-ohms or higher. The reason is I think at low values there was not much change but at higher values the problem starts to appear. I do hope you have a good external supply and again I am happy you found the video useful. John |
| KD0CAC John:
I'l check out with some other values and get here with the info . |

I did a follow up to the Mastech LCR Tester's external power module. The video is on YouTube: http://youtu.be/hA_0GnNO_2A John |

HOLY CRAP IT ACTUALLY HAS A FUSE. ::) Anyway, it lacks a inductor :o |
