Preparing For Calibration
Introduction
The recommended calibration period for the 1000 series calibrators is 12 months.
Extended specifications for 6, 12 and 24 month re-calibration periods are available
from the 1000 series 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 (see “Powering up the
calibrator”, p15 of the 100 series operation manual). Calibration should be performed
in a stable environment where the temperature is stable to within +/- 1ºC during the
calibration.
Equipment Required
To calibrate the 1000 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 1000 series calibrators. For units fitted with additional options additional
equipment is required.

TRANSMILLE LTD. Version 1 : Jul 2015 Page 4
Optional Equipment
To perform a full calibration of a 1000 series multiproduct calibrator additional
equipment may be required dependent upon the capabilities of the multimeter being
used.
For multimeters such as the Agilent 3458A with limited maximum current, a selection
of current shunts are required. These current shunts should be suitable for both DC
and AC current up to. Suggested current shunt values are listed below, along with
the current range they will be used for :
0.1 Ohm –1A to 10A AC/DC
1 Ohm –100 mA to 1A AC/DC
10 Ohm –10.2mA to 100mA AC/DC
100 Ohm –1.02mA to 10mA AC/DC
These shunts are also used for multimeters with insufficient current accuracy for low
current calibration.
