One rule of thumb is to always zero out your calipers before taking a measurement. This involves:
1. Wiping the caliper jaws clean,
2. Closing the jaws to mechanical zero,
3. Confirming that the gauge indicates "0".
Absolutely correct.
Every time I reload I do that check list. Amazing how many times the calipers have slipped and are way off before zeroing. Or some crud has gotten between the jaws and is giving false readings.
I am not particularly anal about slight variances due to pressure on the calipers when I measure something but damn sure will clean them and zero them before using them.
