Calibration Interval
National Instruments recommends a calibration interval of one year for the NI PXIe-4353. You should
adjust the recommended calibration interval based on the measurement accuracy demands of your
application.
Test Equipment
National Instruments recommends that you use the instruments in Table 1 for calibrating an
NI PXIe-4353 module.

Requirements
Voltage calibrator
Fluke 5520A
If this instrument is unavailable for voltage accuracy verification and
adjustment, use a high-precision voltage source with an accuracy of at
least 70 ppm when sourcing up to 50
μ
A.
Resistance calibrator
*
Fluke 5520A
If this instrument is unavailable for resistance accuracy verification and
adjustment, use a high-precision resistance source with an accuracy of
at least 150 ppm 2-wire compensation.
If the resistance source does not have 2-wire compensation, the lead
wire resistance must be included in the total resistance source accuracy.
PXI Express chassis
NI PXIe-1062Q

Calibration accessory
CAL-4353
This accessory is used for module verification and adjustment.
Connecting wires
Banana-jack
terminated copper wire
Copper wire is used for validating the voltage accuracy and adjustment
of the analog input channels. Copper wire is also used for validating the
resistance accuracy and calibration of the CJC resistance input
channels.
*
When connecting the resistance calibrator, keep the lead wires 1.0
Ω
less than the maximum lead compensation specification of the resistance
calibrator. When using the Fluke 5520A, keep the lead wires <1.1
Ω
.
