CALIBRATION
This chapter explains how to calibrate the 6243/44 to ensure that the 6243/44 is used within the specified
accuracy ranges.
In order to use the 6243/44 with the specified accuracy, periodic calibration at least once a year is recom-
mended.
Contact an ADC CORPORATION sales representative for the calibration service.

*1: Use the 6581 under the following conditions.
Integration time: 20 PLC. Auto ZERO: ON. Within 24 hours following INT CAL.
*2: Use 1A for 2 A range full-scale calibration.
*3: When much externally induced noise exists, use shielded cables like A01001, etc.
