4. Calibration
Each module calibrated and finished test before shipment, so usually it is unnecessary to calibrate
the module again, unless the input impedance is changed or the accuracy is lost.
In order to calibrate the module, the following preparations are required:

A single stable calibration source, such as a 3 1/2 digit power supply (or better) or a battery
output.

A single 4 1/2 digit voltage meter (15-bit resolution or better)

A Calibration Program. Please visit ICP DAS website and download demo programs, the
calibration program will be inside.
Tips & Warnings
1. An unstable calibration source will cause calibration errors and will affect the
accuracy of the data acquisition.
2. I-8017HW / I-8017HCW / I-8017DW / I-9017-15 only uses channel 0 to
calibrate every type of range.
3. The gain and offset value of the range of +/- 20 mA for I-8017HW /
I-8017HCW / I-8017DW/I-9017-15 are the same as the range of +/- 2.5V.
If users wish to cal/- 20 mA, cal/- 2.5V will be fine.
4. I-9017 only uses channel 0 to calibrate every voltage range.
5. I-9017 / I-9017C-15 needs to calibrate every channel one by one within the
range of +/- 20mA.
