4. Read the value of the selected ADC reference voltage (+5V, -5V, +10 V
or -10 V) from the DMM and enter it into the software.
5. Review the results in the Status window.
6. (Optional) Check the measured voltage in the Value field for each
reference.
7. (Optional) Save the calibration to a file for later restore, e.g., File | Load
DRA Calibration.
8. (Optional) Update the module to the new calibration factors just obtained
using the Update button. If this step is omitted, the calibration factors will
revert at the next power cycle.
M ADC
The
M ADC
calibration calculates the offset and gain of the monitor to
ADC path for each channel. The Verify button is available for use both before
and after calibration. It is recommended that the calibration be verified before the
Update button is used to store the current M ADC calibration factors. The
Export button can be used to save the calibration factors into a text file for
examination and later restore, e.g., File | Load DRA Calibration.
Select Calibrate Function
Equipment: Basic Setup
Procedure:
1. Place a check mark next the M ADC menu item on the
Calibrate Function menu.
