This function guides you to calibrate the PCI-9113A. The calibration
program serves as a useful test of the PCI-9113A's A/D functions and
can aid in troubleshooting if problems arise.
Note: For an environment with frequently large changes of temperature
and vibration, a 3 months re-calibration interval is recommended.
For laboratory conditions, 6 months to 1 year is acceptable
When you choose the calibration function from the main menu list, a
calibration items menu is displayed on the screen. After you select one of
the calibration items from the calibration items menu, a calibration
window shows. The upper window shows the detailed procedures
which have to be followed when you proceed the calibration. The
instructions will guide you to calibrate each item step by step. The bottom
window shows the layout of PCI-9113A. In addition, the proper Variable
Resister (VR) will blink to indicate the related VR which needs to be
adjusted for the current calibration step.
