10.1 Initial Physical Setup

The gauge should be mounted vertically to a test stand or fixture rugged enough to withstand a load
equal to the full capacity of the instrument. Certified deadweights 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

1. Select Calibration from the menu. The display will appear as follows:

2. Press DIRECTION to invert the display, if desired. ENTER to continue. The display will appear as

follows:

The gauge can be calibrated at up to 10 points in each direction. Enter the number of calibration
points for each direction (compression and tension). At least one point must be selected for each
direction.

Note: To achieve the accuracy specification of ±0.1%, it is recommended to calibrate the gauge
at 5 or more even increments in both the tension and compression directions. For example, a
gauge with capacity of 10 lbF should be calibrated at 2, 4, 6, 8, and 10 lb loads in each direction.
