NI PXIe-4353 Calibration Procedure

Verification Procedure

This section provides instructions for verifying the NI PXIe-4353 specifications.

Tables through 7 in the 

Test Limits

 section show all acceptable settings for the module. Throughout 

the verification process, use Tables 4 through 7 to determine if the module is operating within its 
specified range. Perform verification on all analog input and CJC channels.

Analog Input Voltage Accuracy Verification

Complete the following steps to test the voltage accuracy performance of the module.

1.

Using banana-jack terminated copper wire, connect the positive and negative terminals of the 
voltage calibrator to the terminals labeled INPUT V

Ω

HI and LO of the CAL-4353 while referring 

to Figure 1.

2.

Open a DAQmx calibration session on your device.

3.

Call the DAQmx Connect SC Express Calibration Accessory Channels VI. Configure the 
CAL-4353 by setting the connection to 

_tc_calibration

 and the physical channels 

to

Dev1/ai0:31

.

Note

When MAX configures a module, it is assigned a module name. Each function call uses this 

module name to determine the correct module to adjust. This document uses 

Dev1

 when referring to 

the module name. When you calibrate your module, use the module name assigned to it by MAX.

4.

If you are not using a Fluke 5520A, set the calibrator voltage to a Test Point value indicated in 
Table 4.
