Notes:
1
Specifications valid after a warm-up period of four hours in a stable temperature environment.
2
Specified repeatability is the maximum deviation (±) from the mean value of 90 consecutive readings, with 2-
second averaging. (A 2-second averaging reading is the average of 200 single scans.) Test conditions include
using a gauge pin with a low coefficient of expansion, without removing the gauge pin and with minimal air flow
around the working area of the BenchMike Pro.
3
Specified linearity confirmed using standard factory calibration @ 68 °F at 50% relative humidity. Testing condi-
tions include a measured part composed of material with low coefficient of expansion, with minimal air flow
