NI PXI-4110 Calibration Procedure
Adjustment
Adjustment improves the accuracy of the NI 4110 and updates the calibration date and
temperature in the EEPROM. Perform an adjustment once a year or when the accuracy of
NI 4110 is outside the calibration test limits.
Adjustment corrects the following NI 4110 specifications:
•
Voltage programming accuracy
•
Voltage measurement accuracy
•
Current programming accuracy
•
Current measurement accuracy
The adjustment components of the NI-DCPower API require that you program the NI 4110
using the voltage output and current output functions. You must adjust each range with a separate
call to the appropriate niDCPower Cal Adjust VI or function.
Note
If the NI 4110 passes initial verification and is within all calibration
test limits, NI recommends, but does not require, an adjustment to guarantee the
published specifications for the next year.
Perform the adjustment under the following conditions:
•
Adhere to the guidelines listed in the
section.
•
Perform self-calibration prior to starting the adjustment procedure.
•
Ensure that the ambient temperature is 23 °C ± 1 °C.
