7. CALIBRATION
This chapter describes how to calibrate the 6146/6156 to perform within the specified accuracy ranges.
In order to use the 6146/6156 in the specified accuracies, periodic calibration at least once a year is recom-
mended. (To secure the 90-day accuracy, execute calibration once every 90 days.)
Contact an ADC CORPORATION sales representative for the calibration service.

dard resistance.
