Description

**Computation of the drift rate of calibration constant 72 (will take 1 week to complete):

C = [(A – B) * 1000000] / [A * D] ppm per day

A = the value of the calibration constant 72 (following an ACAL on day 1 of the test)
B = the value of calibration constant 72 (following an ACAL on the last day of the test)
C = the drift rate of calibration constant 72 in ppm per day
D = the number of test days where the instrument was powered on during the test interval
(See Note # 1)
If the absolute value of C is > 0.43 ppm per day, then the A3 assembly in your instrument needs to be
replaced.

Complete an ACAL just prior to obtaining the present value of Calibration Constant 72
