4.1 Calibration and guaranteed values
We recommend that you send in your test sets for calibration at least once a year.
The drift of test equipment, that is, the deterioration of accuracy over time, depends strongly on
environmental conditions and the application field. Excessive use or mechanical and/or thermal stress
may result in the need for shorter calibration intervals.
Moderate working environments, on the other hand, allow you to increase the calibration interval to once
every 2 or even 3 years.
► Particularly in cases of extended calibration intervals, verify the accuracy of the test set by cross-
referencing the measurement results with traceable reference equipment either on a regular basis or
prior to use. You can, for example, use a typical, often-used device under test as a reference, or use
measurement equipment with a certified high accuracy.
Should the test equipment fail, immediately contact OMICRON Support for calibration or repair. Do not
try to use it anymore.
Guaranteed values
• The values apply at 23 °C ± 5 °C (73 °F ± 9 °F), and after a warm-up time greater than 25 minutes.
• Guaranteed values of the generator outputs:
The values are valid in the frequency range from 10 to 100 Hz unless specified otherwise. Given
maximum phase errors relate to the voltage amplifier outputs.
• Accuracy data for analog outputs are valid in the frequency range from 0 to 100 Hz unless specified
otherwise.
• The given input/output accuracy values relate to the range limit value (% of range limit value).
