Calibration Check Standard (Moisture only)
Purpose: Verification of instrument stability over time.

Description: A canister containing 2 standards which simulate a low and a high moisture absorption.

Connection: Align 2 fixed pins on light shroud with holes in the canister then lock in position by tightening thumbscrew.

Use: As a stability check – With the MCT set to the same CAL channel as used to measure the product, note down the MCT reading from the low side of the cannister. Undo the thumbscrew holding the canister in position, invert it, then retighten. Note the MCT reading again. Future readings, taken at two weekly or monthly intervals should lie within +/- 0.2* of the initial recorded value, if this isn't the case, the gauge may not be functioning optimally.

* With a span of 25. higher spans will give rise to larger deviations from the initial calcheck readings.

Note: Cal Checks can also be used for an approximate calibration transfer, please see Installation Manual for details.
