error. If the voltage source is floating with respect to the computer and
you have not connected the calibrator GND to ACH0GND, you
receive an error.
8. Call
Copy_Const
to enable and copy the new calibration constants to
the protected factory portion of the EEPROM and to update the
calibration date. This function is also included in the
niECal.dll
.
9. Call
Calibrate_E_Series
to set the factory-calibration constants as
the default constants. Set the following parameters:
• deviceNumber —The value obtained from MAX
• calOP —
ND_SET_DEFAULT_LOAD_AREA
• setOfCalConst —
ND_FACTORY_EEPROM_AREA
• calRefVolts —
0
10. Disconnect the calibrator from the device.
The device is now calibrated with respect to the external source.
Reverifying the Device
After the device is calibrated, you may want to reverify the analog input
and output operation. To do this, repeat the procedure in the
Verifying the
Performance of the NI 6110/6111/6115/6120 section.
NI 6110/6111/6115/6120 Specifications
The tables in this section contain the specifications for the
NI 6110/6111/6115/6120. The specifications include analog input, analog
output, and counter/timer values. NI 6110/6111 devices share one set of
tables. The NI 6115 and NI 6120 each have a set of tables.
The tables display the specifications for 1-year and 24-hour calibration
intervals. The 1-year ranges display the specifications that the device
should meet if it has been one year since it was calibrated, but after a device
has been calibrated with an external source, the values shown in the
24-hour tables are the valid specifications.
Using the Tables
The following sections describe how to use the specification information.
Range
Range refers to the maximum allowable voltage range of an input or output
signal. For example, if a device is configured in bipolar mode with a range
of 20 V, the device can read signals b10 and –10 V.
