E.1 Procedure Description

 • Verication-TestingCalibration - Certied weights are applied in tension

and compression to determine if the FDX can be certied and if the calibration

procedure is necessary.

 • Calibration - The FDX has Auto-Calibration enabling the gage to be calibrated

by one full capacity test weight.

E.2 Verication-TestingCalibration

Warm-up FDX for 2-3 minutes after power-on to stabilize the electronics.

To verify, a ve-point tension and compression test is recommended with weights

equal to 20%, 40%, 60%,80%, and 100% of FDX capacity. If the displayed weight

differs more than ±0.3% of full scale ±1 least signicant digit, FDX is out of tolerance.

Accuracy verication requires testing xtures: a test stand capable of supporting

weights equal to the FDX capacity, and xtures for applying test weights in tension

and compression. Testing xtures are available from Wagner Instruments.

E.3 Auto-Calibration (L CAL)

Auto-Calibration is used to return the FDX to its specied accuracy after verication

indicates the FDX is out of tolerance, or if obvious that readings are incorrect.

Certied NIST traceable test weights are recommended, resulting in an NIST

Calibration Certicate. Test weights are available from Wagner Instruments.

Unless FDX is tested with E.2 verication and an NIST Calibration Certicate

issued, FDX is not certied to NIST standards. If certication is not required,

Auto-Calibration is adequate in returning FDX to specied accuracy.

E.2Verication.

E.3.1 Auto-Calibration (LCAL) Procedure

Test weights must match the Force Cell Module capacity to be tested.

Set UNITS to lbf - all calibrations are performed in pounds (lbf).

Attach FDX to the calibration test stand, and stop all movement.

Enter the set-up menu:

• Turn FDX off.

• Push / Hold ZERO; push ON/OFF.

• Release ON/OFF, then ZERO, AoFF is displayed.

Gage set-up:

• SCROLL to L CAL option.

• Push SELECT - FDX displays null.

• Push SELECT - FDX displays a force cell capacity after zero ashes.

If the capacity shown is not that of the attached Force Cell Module, SCROLL

to the correct Force Cell Module capacity and proceed.
