CHAPTER 9
CALIBRATION
9.1 CALIBRATION INTERVAL
Periodic re-calibration of the ADC-16 is necessary for accuracy, with the interval of recalibration based
on
type
of service. For example, an environment with frequent large changes of temperature and/or
vibration would call for a 3-month re-calibration interval, while laboratory or office conditions would
call for six months to one year.
9.2 CALIBRATION PROGRAM
Your Distribution Software contains the calibration program ADCZ6CAL.EXE is provided to step you
through the calibration process. To run ADClGCAL.EXE, log to the ADC-16 directory and type
ADC16CAL
.
From the opening menu, select as follows:
