NI 5412 Calibration Procedure
32. Call
niFgen_SetAttributeViBoolean
to disable the analog output (niFgen property
node:
Basic Operation»Output Enabled
) using the following parameters:
•
vi
: The session handle returned from
niFgen_InitExtCal
•
channelName
:
"0"
•
attributeID
:
NIFGEN_ATTR_OUTPUT_ENABLED
•
value
:
VI_FALSE
33. Call
niFgen_SetAttributeViInt32
to set the calibration ADC input (niFgen
property node:
Calibration»Cal ADC Input
) using the following parameters:
•
vi
: The session handle returned from
niFgen_InitExtCal
•
channelName
:
""
(empty string)
•
attributeID
:
NIFGEN_ATTR_CAL_ADC_INPUT
•
value
:
NIFGEN_VAL_GROUND
34. Call
niFgen_Commit
(niFgen Commit VI) to commit the attribute values to the device
using the following parameter:
•
vi
: The session handle returned from
niFgen_InitExtCal
Closing the External Adjustment Session
When you have completed all the adjustment stages, you must close the external adjustment
session to store the new calibration constants in the onboard EEPROM.
Call
niFgen_CloseExtCal
(niFgen Close Ext Cal VI) using the following parameters:
•
vi
: The session handle returned from
niFgen_InitExtCal
•
action
:
–
If the external adjustment procedure completed without any errors, use
NIFGEN_VAL_EXT_CAL_COMMIT
. This function stores the new calibration
constants, updated calibration dates, updated calibration temperatures in the onboard
EEPROM.
–
If any errors occurred during the external adjustment procedure or if you want to abort
the operation, use
NIFGEN_VAL_EXT_CAL_ABORT
. This function discards
the new calibration constants and does not change any of the calibration data stored in
the onboard EEPROM.
