PERFORMING CALIBRATION
Calibration always begins by establishing a zero (no-load) reference. A complete calibration also
requires establishing a span (test load) reference. This section details various methods for
obtaining zero and span references.
Establishing Zero
The Model 370/375 provides five methods for obtaining a zero (no load) calibration reference,
First Zero, Last Zero, False Zero, Only Zero, and Cal Reset.
