Calibrate_E_Series
Format
status = Calibrate_E_Series (deviceNumber, calOP, setOfCalConst, calRefVolts)
Purpose
Use this function to calibrate your E Series device and to select a set of calibration constants
to be used by NI-DAQ.
Caution Read the calibration chapter in your device user manual before using
Calibrate_E_Series.
Note Analog output channels and the AO and WFM functions do not apply to the AI
ESer ies devices.

Parameter Discussion
The legal ranges for the calOp and setOfCalConst parameters are given in terms of con stants
that are defined in the header file. The header file you should use depends on which of the
following languages you are using:
• C programmers—NIDAQCNS.H (DATAACQ.H for LabWindows/CVI)
• BASIC programmers—NIDAQCNS.INC
• Pascal programmers—NIDAQCNS.PAS
calOP determines the operation to be performed.
Range:
ND_SET_DEFAULT_LOAD_AREA—Make setOfCalConst the default load area; do not
perform calibration.
ND_SELF_CALIBRATE—Self-calibrates the device.
ND_EXTERNAL_CALIBRATE—Externally calibrates the device.
Name Type Description
