Appendix D Calibration

The PCI-1724U has been well calibrated at the factory, so it is normally

not necessary to calibrate the PCI-1724U for initial use. However, if some

special conditions have to be met, calibrate the PCI-1724U by the

procedure shown below.

To perform an effective calibration, a standard 4-1/2 digits resolution

measurement meter has to be used.

There are 2 calibration procedures in PCI-1724U. Which procedure to use

depends on what range that is selected:

• Voltage Calibration ( -10 V ~ 10 V)

• Current Calibration ( 0~20 mA, 4~20 mA)
