10 CALIBRATION
10.1 Initial Physical Setup
The sensor should be mounted vertically to a test stand or fixture rugged enough to withstand a load
equal to the full capacity of the sensor. Certified deadweights, torque arms/wheels, and/or master load
cells should be used, along with appropriate mounting brackets and fixtures. Caution should be taken
while handling such equipment.
10.2 Calibration Procedure
In the interests of simplicity and brevity, the following instructions use force terminology only. Such
wording is displayed only when a force sensor is being calibrated. When a torque sensor is being
calibrated, the terms
COMPRESSION and TENSION are replaced by CLOCKWISE and COUNTER-
CLOCKWISE , respectively.
1. Select Calibration from the menu. The display appears as follows:
