Calibration - Omega ISA- BUS MULTI-FUNCTIONAL BOARD OME-A822PG Hardware Manual

5.2.2 CALIBRATION

The CALIBRATION menu contains ten submenu items: they are, D/A Reference voltage,
D/A Channel 0 gain, D/A channel 1 gain, A/D Gain, A/D Offset, A/D Bipolar Offset, A/D
Unipolar Offset. These items relate to the calibration of the OME-A-822PGL/PGH. The
CALIBRATION main menu, is a graphic representation of the OME-A-822PGL/PGH board
layout. In order to maintain the specified performance, it may be required to calibrate the
board after working with it for an extended period of time. There are seven variable resistors
(VRs) that need to be adjusted during the calibration process. When you highlight one of the
first seven menu items, the associated VR will begin to blink and a message window will
appear that will instruct you how to adjust the VR. The main menu screen is shown below.
