You have finished adjusting the NI 5122/5124. It is not necessary to adjust
each channel individually. However, you should repeat the entire
verification procedure to verify a successful adjustment.
Calibration Utilities
NI-SCOPE supports several calibration utilities that allow you to retrieve
information about adjustments performed on the NI 5122/5124, change the
external calibration password, and store small amounts of information in
the onboard EEPROM. You can retrieve some data using MAX, however,
you can retrieve all the data programmatically using NI-SCOPE functions.
MAX
To retrieve data using MAX, complete the following steps:
1.
Select the device from which you want to retrieve information from
My System»Devices and Interfaces»NI-DAQmx Devices
.
2.
Select the
Calibration
tab in the lower right corner.
You should see information about the last date and temperature for both
external and self-calibration.
