Replacing Precision Resistors, TT-1A

[bob91343]

One ploy that will improve accuracy a little is to short the leads and subtract the reading you get from your measurements. But the typical DVM may be off by 1% easily. In fact, there are calibration adjustments inside that may need attention.

I have some precision bridges and find them extremely useful; I don't know how I got along without them. My very accurate voltmeters argue with one another about the actual voltage. As the saying goes, a man with a watch knows the time but a man with two watches is never sure.
