8. CALIBRATION
This chapter describes how to calibrate the 6240B to perform within the specified accuracy ranges.
In order to use the 6240B in the specified accuracies, periodic calibration at least once a year is recom-
mended.
Contact an ADC CORPORATION sales representative for the calibration service.
