2000I & 2000M Instrument’s User Guide, Revision B
62
If any errors are detected during the internal calibration and test sequence, the
instrument displays a warning message:
If the error is minor, such as an error not affecting performance, then the
message displays for approximately two seconds and the sequence is con-
tinued.
If the error is major, such as an error that seriously affects the performance
then the message continuously displays and the sequence is suspended at
that stage.
External Calibration
The 2000 instruments require periodic calibration (e.g., physical adjustment)
against external
calibration standards to maintain the published specifications.
The period at which these calibrations are performed is dependant on your accu-
racy requirements, as shown in the accuracy tables in
Appendix A-Power Output
Capacities
Vitrek
recommends calibration intervals of 90 days, 6 months or 1
year to meet your in house accuracy needs. For example: in some applications,
such as, general engineering laboratories and process control envi-ronments, the
1 year accuracies may be excessive. In these cases a 3-year interval may be
satisfactory.
Equipment Required to Recalibrate
High precision DC voltage measuring equipment is required to accurately cali-
brate the 2000 instruments. The objective is an accuracy margin better than those
shown in Tables 2 and 3.
