Select the type of calibration to be performed, i.e., Nameplate, Two-Point, or Shunt. Then

edit the Application Parameters, if applicable. A brief description of the three calibration

methods follows. When done, click the <Continue> button.

•

Nameplate calibration provides a way to enter parameters for your strain gage

and its application. The final step of the procedure includes attaching the strain

gage (load cell).

•

Two-Point calibration provides a way to calibrate a DBK16, DBK43,

DBK43A, or DBK43B that is using a strain gage with unknown specifications.

In this method, the user enters two points of transducer output [milli-volts] vs.

engineering units, e.g., pounds. GageCal provides set up instructions based on

the parameters entered. The final step of the procedure includes attaching the

strain gage (load cell).

•

Shunt calibration provides a means calibrating channels with use of user-

supplied shunts to simulate a physical load. With this method, 1 or 2 shunt

resistors (Rn00D and Rn00H) are added for each of the 8 channels to be

calibrated. You must set J3 to the position closest to TP9 for the shunt

calibration to work correctly. Shunt calibration is performed with the load-cell

attached.

Follow GageCal’s screen prompts to complete the calibration.

Note: You can use GageCal’s “Diagnostics” feature to view a graphic representation

of the strain gage and the card’s gain stages.

After completion, go to DaqView and convert ±5 V to engineering units using mx+b.
