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.
Calibration Utilities
NI-FGEN supports several calibration utilities that allow you to retrieve
information about adjustments performed on the NI 5421/5441, restore an
external calibration, change the external calibration password, and store
small amounts of information in the onboard EEPROM. You can retrieve
some data using MAX or the FGEN SFP; however, you can retrieve all
the data using NI-FGEN.
MAX
To retrieve data using MAX, complete the following steps:
1.
Launch MAX.
2.
Select the device from which you want to retrieve information from
My System»Devices and Interfaces»NI-DAQmx Devices
.
3.
Select the
Calibration Tab
on the lower right corner.
You should see information about the last dates and temperature for
both external and self-calibration.
FGEN SFP
To retrieve data using the FGEN SFP, complete the following steps:
1.
Launch the FGEN SFP.
2.
Select the device from which you want to retrieve information using
the Device Configuration dialog box (
Edit»Device Configuration
).
3.
Open the Calibration dialog box (
Utility»Calibration
).
You should see information about the last dates for both external and
self-calibration.
