5.1 Introduction
Regular calibration checks are important to maintain accuracy in data
acquisition and control applications. To assist users in the A/D
calibration process, we provide one calibration program, ADCAL.EXE,
on the PCI-1713 software CD-ROM.
The ADCAL.EXE program makes A/D calibrations easy. It leads you
through the calibration and setup procedure with a variety of prompts
and graphic displays, showing you all of the correct settings and
adjustments. This chapter offers a brief guide to these calibration
programs.
To perform a satisfactory calibration, you need a 4

multimeter and a voltage calibrator or a stable, noise free D. C. voltage
source.
5.2 VR Assignment
There are four variable resistors (VRs) on the PCL-1713 card. They
help you to make accurate adjustments on all A/D channels. Please
refer to the following figure for VR positions.
