NI 5105 Calibration Procedure
Adjustment
If the NI 5105 successfully passed each of the verification procedures within the calibration test
limits, an adjustment is recommended but not required to guarantee the published specifications
for the next two years. If the device was not within the calibration test limits for each of the
verification procedures, you can perform the adjustment procedure to improve the accuracy of
the device. Refer to
to determine which procedures to perform.
An adjustment is required only once every two years. Completing the adjustment procedure
automatically updates the calibration date and temperature in the EEPROM of the device.
Complete all of the following steps to externally adjust the NI 5105.
1.
Obtain an instrument session handle using the niScope Cal Start VI.
