PXIe-4310 Calibration Procedure
3.
Initiate self-calibration using one of the following methods:
•
Click
Self-Calibrate
in the upper right corner of MAX.
•
Right-click
NI PXIe-4310
and select
Self-Calibrate
from the drop-down menu.
Note
Once self-calibration is completed, maintain the device temperature within
±1 °C of the self-calibration temperature.
Note
NI recommends self-calibrating using MAX, although you can also
self-calibrate programmatically.
Checking Device Temperature Changes
Device temperature changes (greater than ±10 °C since the previous external calibration or
greater than ±1 °C since the previous self-calibration) can cause you to incorrectly verify and
adjust your device. After self-calibrating your device as described in the
section, complete the following steps to compare the current device temperature to the
temperatures measured during the last self-calibration and external calibration in MAX.
1.
Launch MAX.
2.
Select
My System»Devices and Interfaces»PXIe-4310
.
3.
Click the
Settings
tab. Temperature information is displayed in the Self-Calibration and
External Calibration sections of the
Settings
tab.
Accuracy Verification
This section provides instructions for verifying the PXIe-4310 specifications.
Throughout the verification process, use Table 4 to determine if your device needs to be
adjusted.
Since PXIe-4310 modules have many different ranges, you must check measurements for each
available range. You must perform verification on all ranges of all analog input channels of
PXIe-4310 modules in differential mode.
Note
The test limits used in this document assume a maximum temperature drift of
±10 °C from the last external calibration, and a maximum temperature drift of ±1 °C
from the last self-calibration. Refer to the
Checking Device Temperature Changes
section for more information and instructions on reading your device temperature and
comparing it against the device temperature during the last external calibration.
Complete the following steps to verify the analog input:
Note
The TB-4310 (600V) cannot be used for verification or adjustment of the
PXIe-4310.
1.
Connect the output of the calibrator to the TB-4310 (10V) as shown in Figure 1.
2.
Connect the TB-4310 (10V) to the PXIe-4310.
