NI PXIe-4353 Calibration Procedure
6.
Perform an external calibration adjustment by selecting the DAQmx Adjust 4353 Calibration VI,
from the DAQmx Adjust SC Express Calibration polymorphic VI. Set the physical channels
to
Dev1/ai0:1
. The reference value parameter is the actual output of the calibrator, 70 mV.
7.
Set the calibrator to output –70 mV and wait for the calibrator output to settle.
8.
Perform an external calibration adjustment by selecting the DAQmx Adjust 4353 Calibration VI,
from the DAQmx Adjust SC Express Calibration polymorphic VI. Set the physical channels
to
Dev1/ai0:1
. The reference value parameter is the actual output of the calibrator, –70 mV.
9.
Disable the calibrator output.
10. Set the resistance calibrator to 2-wire compensation mode.
11. Configure the CAL-4353 using the DAQmx Connect SC Express Calibration Accessory
Channels VI. Set the connection to
_cjc_calibration
and the physical channels
to
Dev1/_cjtemp0
.
12. Set the calibrator to resistance mode. Set the calibrator resistance to 32.4 k
Ω
and wait for the
calibrator output to settle.
