H. CALIBRATION

To ensure accuracy in force measurement, the FDV Digital Force

Gage should be tested periodically to confirm that it is within

tolerance.

H.1 Testing Calibration

The FDV Digital Force Gage is accurate to ±0.3% of the gage's full

scale capacity. To test calibration, a four point test is recommended, at

weights equal to 25%, 50%, 75%, and 100% of the gage capacity. Four

test weights, corresponding to the above percentages, are required. If

the displayed weight should differ from the value of the test weight by

more than 0.3%, the gage is out of calibration. Remember to tare any

attachments prior to testing by pressing ZERO with the FDV shaft and

hook attachment pointing down.

RECOMMENDATION: Warm-up time for the FDV is recommended.

After initial power-on, allow 2-3 minutes for the electronics to stabilize.

This will improve accuracy of reading.

Since the FDV Force Gage consists of two separate parts, the Force

Display Module (FDM) and the Force Cell Module (FCM), the total

accuracy of the gage depends on the tolerance to specifications of

either one or both of the modules. If the FDV does not meet the rated

0.3% accuracy, the gage should be returned to Wagner Instruments for

evaluation and recalibration of the modules. Call Wagner Instruments

for instructions prior to shipping.

H.2 Auto-Calibration

Factory calibration is recommended but in special situations the gage

may be calibrated in the field using the Auto-Calibration feature.

1. If the FDV is used ONLY as a non-interchangeable unit - only one

Force Cell Module is used with only one Force Display Module - then

the unit may be calibrated using the procedure outlined in Section H.3.
