Preparing For Calibration
Introduction
The recommended calibration period for the 3000A series calibrators is 12 months.
Extended specifications for 6, 12 and 24 month re-calibration periods are available
from the 3000A extended specifications
Calibration can be achieved using one of two methods:
1. Manual calibration via the front panel controls.
2. Automated closed-loop calibration using ProCal calibration software
In both instances the calibrator should be switched on and allowed to warm up for
the required period as stated in the operator’s manual. Calibration should be
performed in a stable environment where the temperature is stable to /- 1ºC
during the calibration.
Equipment Required
To calibrate the 3000A series calibrators the following equipment is required:
1. High Accuracy precision Multimeter (example Transmille 8081 / Agilent 3458A opt
002 / Fluke 8508A)
2. LCR Bridge (example Agilent
3. DC Voltage Source (example Transmille 3000 series multiproduct calibrator, Fluke
55xx series multiproduct calibrator
4. High Accuracy Frequency Counter / GPS Frequency Reference / Off-Air
Frequency Reference
Between these four pieces of equipment it is possible to calibrate all basic functions
of the 3000 series calibrators. For units fitted with additional options additional
equipment is required
Optional Equipment
To perform a full calibration of a 3000A series multiproduct calibrator additional
equipment may be required dependent upon the capabilities of the multimeter being
used
