NI 5622 Calibration Procedure
Password
A password is required to open an external calibration session. If the
password has not been changed since manufacturing, the password is
NI
.
Calibration Interval
External Calibration
The measurement accuracy requirements of your application determine
how often you should externally calibrate the NI 5622. NI recommends
that you perform a complete external calibration at least once every year.
You can shorten this interval based on the accuracy demands of your
application.
Self-Calibration
You can perform self-calibration whenever necessary to compensate for
environmental changes.
Caution
Although you can repeatedly self-calibrate, self-calibrating the NI 5622 more
than a few times a day may cause excessive wear on the relays over time.
Test Equipment
Table 3 lists the equipment required for externally calibrating the NI 5622.
If you do not have the recommended instruments, use these specifications
to select a substitute calibration standard.
