6 Calibration
6.1 Calibration Periods
PREMA recommends that the unit be calibrated after one year has elapsed.
Within that year, specification data are guaranteed to be valid.
6.2 PREMA Calibration Service
You can have your unit calibrated by PREMA or by a local calibration lab. Call the
telephone number indicated on the front of the manual, in order to obtain information
about the price and duration of this service. We make every effort to return the unit to
your use as quickly as possible. In addition, when we perform a full calibration, you
receive a factory certificate.
Calibrations with an official certificate can also be obtained from PREMA.
6.3 Necessary Equipment
The following aids should be available to you, in order to be able to carry out a
complete calibration of the unit:
• Multifunction Calibrator for DC Voltage, DC Current, AC Voltage, AC
Current, and Resistance to at least 100MΩ, with a minimum resolution of 6½
digits (e.g. Datron 4800), or
• Voltage Standards (e.g. Fluke 732A, 10V) and Resistance Standards and
• Short-Circuit Terminators (three of them, e.g. PREMA 3016 Short-Circuit
Terminator Set) in order to perform the zero correction.
• Connection cables with gold-plated Banana Plugs (e.g. PREMA 3014 or 3015,
Precision Cable Set)
As an alternative you can also utilize less precise sources with good short-time
stability; the value of the source can be checked with PREMA’s 8½ digit DMM 6048.
You can then enter the DMM 6048’s reading into the 5017 as calibration value.
With this method, even 5½ digit calibrators can be used to calibrate 7½ digit
multimeters.
