5: Copy the entire calibration table in calibrationArea to driver memory so
NI-DAQ can use the table in subsequent scaling operations in the current
NI-DAQ session (SCXI-1122, SCXI-1124, SCXI-1126, and SCXI-1141 only).
calibrationArea is the location NI-DAQ uses for the calibration constants. Read the
following Using This Function section for an explanation of the calibration table stored in
NI-DAQ memory and the SCXI-1122, SCXI-1124, SCXI-1126, and SCXI-1141 EEPROM
organization.
0: NI-DAQ memory. NI-DAQ maintains a calibration table in memory for use in
scaling operations for the module.
1: Default EEPROM load area. NI-DAQ also updates the calibration table in
memory when you write to the default load area (SCXI-1122, SCXI-1124,
SCXI-1126, and SCXI-1141 only)
2: Factory-set EEPROM area. You cannot write to this area, but you can read or
copy from it (SCXI-1122, SCXI-1124, SCXI-1126, and SCXI-1141 only).
3: User EEPROM area (SCXI-1122, SCXI-1124, SCXI-1126, and SCXI-1141
only).
rangeCode is the voltage or current range of the analog output channel. NI-DAQ only uses
this parameter for SCXI analog output modules.
0: 0 to 1 V.
1: 0 to 5 V.
2: 0 to 10 V.
3: –1 to 1 V.
4: –5 to 5 V.
5: –10 to 10 V.
6: 0 to 20 mA.
SCXIgain is the SCXI module or channel gain/range setting. NI-DAQ only uses this
parameter for analog input modules. Valid SCXIgain values depend on the module type:
SCXI-1100: 1, 2, 5, 10, 20, 50, 100, 200, 500, 1,000, 2,000.
SCXI-1120: 1, 2, 5, 10, 20, 50, 100, 200, 250, 500, 1,000, 2,000.
SCXI-1120D: 0.5, 1, 2.5, 5, 10, 25, 50, 100, 250, 500, 1,000.
SCXI-1121: 1, 2, 5, 10, 20, 50, 100, 200, 250, 500, 1,000, 2,000.
SCXI-1122: 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 100, 200, 500, 1,000, 2,000.
SCXI-1126: 250, 500, 1,000, 2,000, 4,000, 8,000, 16,000, 32,000, 64,000, 128,000.
SCXI-1140: 1, 10, 100, 200, 500.
SCXI-1141: 1, 2, 5, 10, 20, 50, 100.
DAQboard is the DAQ device you are using with this SCXI module. This applies only when
opCode = 0, 1, 2, or 3 and moduleSlot is an analog input module. Otherwise, set to 0.
DAQchan is the analog input channel of DAQboard that you are using with this SCXI
module. If you have only one chassis connected to DAQboard and moduleSlot is in
multiplexed mode, DAQchan should be 0. calConst1 will be scaled by the current input
