Omega OMB-DAQBOARD-3000 Calibration 4

Calibration 4

DaqBoard/3000 Series boards are factory-calibrated. However, if adjustments are needed they should be

completed in the following order:

1. Analog Measurement Path, Offset and Gain

2. Voltage Reference

3. DAC0 Offset and Gain *

4. DAC1 Offset and Gain *

5. DAC2 Offset and Gain *

6. DAC3 Offset and Gain *

*In regard to DAC applicability:

DaqBoard/3000 – DAC0 and DAC1 apply

DaqBoard/3001 – DAC0, DAC1, DAC2, and DAC3 apply

DaqBoard/3005 – No DACs apply

DaqBoard/3006 – No DACs apply

Note: DaqBoard/3006 has one fixed range of ±10V.

A Windows-based program, DaqCal.exe, is used to calibrate Daq systems, including analog expansion

cards. DaqCal.exe is used in conjunction with:

• a 6.5-digit, digital multi-meter

• an adjustable voltage calibrator

• an ambient temperature meter

To use the calibration program:

1. Launch DaqCal.

Note: DaqCal is installed automatically from your data acquisition CD as a part of product

support. This takes place during software installation. DaqCal’s default location is the

Omega DaqX Software folder, in the Programs group.

2. When DaqCal opens you will be prompted to select your device from a list. After doing so,

simply follow the illustrated on-screen instructions.

Reference Note:

We have incorporated a copy of the DaqCal User Calibration Utility Guide

(p/n 457-0931) with this chapter. The guide includes information regarding NIST

(National Institute of Standards and Technology) traceability, and equipment and setup

information. Though far from all encompassing, the general guide should give you a good

understanding as to how DaqCal is used.
