Copy that. The power supply reads out to one place & your DMM reads out to two places.
The DMM is more precise & only more more accurate if it's calibrated. Precision & accuracy are not the same. |

Yup Former USAF electronics tech. Fully familiar with using a $3000 (in 1980s dollars) HP bench DMM with resolution to the 4th decimal place with fully traceable calibration to measure a stupid 9v battery. No need for that type of accuracy or precision for automotive hobby work. Even working on complicated electronics it was very rare to ever need that level of accuracy and precision. Flukes were disposed of like toilet paper (IMG:style_emoticons/default/sad.gif) The sad joke was that if you were going to break or lose a piece of test equipment, make sure it was something big and expensive like a $12k O-scope or $30k spectrum analyzer. They can withhold a Fluke out of your check via GPLD if they felt so inclined (Government property Lost or Damaged) but when you made $12k a year; they were never going to recoup something expensive. |
