Calibration
The subsequent information describes how to calibrate the Product to external
standards. Substitute either manual or automated equivalent equipment and
methods for these calibration procedures, after taking in consideration product
specifications and substituted measurement equipment uncertainty. During
calibration, select the fast, medium, or slow filter.
Calibrating (Calibration Adjustment) the Main Input
Calibrate INPUT1 or INPUT2 by using the following sequence of procedures:
1. Characterize the dc source.
2. Perform dc calibration adjustment.
3. Perform ac calibration adjustment.
Throughout the dc and ac calibration adjustment, the control display prompts you
with the next step and informs you about the progress of calibration. The cable
connections for the dc and ac calibration are kept as similar as possible so that a
minimum number of mechanical changes are required during the procedure.
INPUT 1 and INPUT 2 are equivalent. Calibration adjustment of INPUT 1 or
INPUT 2 will result in adjustment of the product for use of either INPUT.
