4.6 More About Calibration
The following provides additional information about compensating for environmental factors (Section 4.6.1) and also
provides diagnostic information for
determining expected zero and span coefficients.
4.6.1 Adjusting Final Calibration
Calibration may be affected by environmental factors including wind, vibration, and angular loading. For example,
if the scale is calibrated with 1000 lb, a strain test may determine that at 2000 lb the calibration is 3 lb high. In this
case, final calibration can be adjusted by tweaking WVAL to 998.5 lb. This adjustment provides a linear correction
of 1.5 lb per 1000 lb.
To adjust the final calibration, return to the
WVAL prompt and press TAR E (Enter) to show the test weight value. Press
or to adjust calibration up or down. Press the Calibrate softkey to save the value, and press to return to the
CALIBR menu.
