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)
