should be completed in the following order:
1. PGA Input and Output Offset
2. Sample/Hold Offset
3. A/D Offset and Gain
4. VDC Voltage Reference
5. DAC0 Full-Scale*
6. DAC1 Full-Scale*
7. DAC2 Full-Scale*
8. DAC3 Full-Scale*
*In regard to the various DaqBoard/1000 and /2000 Series boards, DAC applicability is as follows:
DaqBoard/1000 – DAC0 and DAC1 apply
DaqBoard/1005 – No DACs apply
DaqBoard/2000 and /2000c– DAC0 and DAC1 apply
DaqBoard/2001 and /2001c– DAC0, DAC1, DAC2, and DAC3 apply
DaqBoard/2002 and /2002c– No DACs apply
DaqBoard/2003 and /2003c– DAC0, DAC1, DAC2, and DAC3 apply
DaqBoard/2004 and /2004c– DAC0, DAC1, DAC2, and DAC3 apply

A Windows-based program, DaqCal.exe, is used to calibrate Daq systems, including analog expansion
cards. DaqCal.exe is used in conjunction with:
•
a 4.5-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
IOtech 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.
