POLMANTEO has got a calibration centre with electronic instruments for the generation and measurement of voltage/current (direct and alternating) and resistance.
The history of the Calibration Centre originated in 2005 when technical, military and civil personnel started to provide the basis for the realization of a Metrological room that had to maintain the efficiency of the tools used in electronic and opto-electronic laboratories.
Thanks to techniques and professionals with great experience in the sector, it has been possible to develop growth and updating activities, in terms of personnel and instruments.
The Centre is formed by an instruments room with a metrological cabin with constant temperature and humidity, thanks to a conditioning system electronically controlled.
The present "core" of the metrological cabin is composed of standard calibrators and primary samples.
Primary samples of resistance and direct voltage
The multifunctional calibrator
- FLUKE 5720A model - Multifunctional DC/AC Calibrator

All instruments undergo annual calibration at the Metrological Research National Institute (I.N.RI.M.) in Turin. The routine operations and management are controlled and archived by a computerized system that guarantees the right management of technical data and environmental working conditions.
Here there is an example of an unbroken Chain of reference between the Centre for the dissemination of Units on the national territory and the final customer passing through the Calibration Centre.
The calibration capabilities of the Centre are:
- Calibration of laboratory samples
- Calibrators
- Multifunctional calibrators
- Analogue and numeral multimeters
- Analogue and numeral multifunctional multimeters
- Calibration of DC and AC Generators
- Time basis calibration at 10 MHz of all electronic instruments
- Calibration of analogue and digital Oscilloscopes up to 600 MHz
