Calibration

In data acquisition process, how to calibrate your measurement devices to maintain its accuracy is very important. Users can calibrate the analog input and analog output channels under the users' operating environment for optimizing the accuracy. This chapter will guide you to calibrate your PCI-9112 to an accuracy condition.

6.1What do you need

Before calibrating your PCI-9112 card, you should prepare some equipment’s for the calibration:

ØCalibration program : Once the program is executed, it will guide you to do the calibration. This program is included in the delivered package.

ØA 5 1/2 digit multimeter (6 1/2 is recommended)

ØA voltage calibrator or a very stable and noise free DC voltage generator.
