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