NI PXIe-4322

 

Calibration Procedure

e.

Measure the current using the DMM.

f.

Call the 4322 instance of the DAQmx Adjust SC Express Calibration function and 
configure it as follows:

g.

For each adjustment point from the first to the tenth, repeat steps d to f.

h.

For the eleventh point, change the DMM input range to 100 µA then repeat 
steps d to f.

i.

Repeat steps b to h for every channel.

j.

Close the calibration session.

4.

Disconnect the DMM from the terminal block.

EEPROM Update

When an adjustment procedure is completed, the NI PXIe-4322 internal calibration memory 
(EEPROM) is immediately updated.

If you do not want to perform an adjustment, you can update the calibration date and onboard 
calibration temperature without making any adjustments by initializing an external calibration

,

 

and closing the external calibration.

Re-Verification

Repeat the 

Verification

 section to determine the As-Left status of the device.

Note

If any test fails Re-Verification after performing an adjustment, verify that 

you have met the 

Test Conditions

 before returning your device to NI. Refer to 

Where 

to Go for Support

 for assistance in returning the device to NI.

Specifications

Refer to the 

NI PXIe-4322 Specifications

 for detailed specification information.
