62 2000I & 2000M Instrument’s User Guide, Revision B 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 continued. 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 accuracy requirements, as shown in the accuracy tables in Appendix A-Power Output Capacities. Xitron Technologies 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 environments, 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 calibrate the 2000 instruments. The objective is an accuracy margin better than those shown in Tables 2 and 3.
