Note that although the BenchMike Pro will operate as specified throughout the safe operating temperature range
shown in the table above, the temperature of the part being measured can affect measurements. During factory
calibration, measured parts are allowed to stabilize at standard conditions of 68°F (20°C) and 50% relative humid-
ity. Your product may expand or contract based on its temperature. For best results, measure parts that have sta-
bilized to these standard conditions. At all other temperatures, the size should be determined by using the coeffi-
cient of thermal expansion for the specific material composition of your product. (See the Troubleshooting section
in the BenchMike Pro Operator Guide.) It is particularly important during mastering to ensure that your gauge pins
have stabilized at standard conditions.
