Calibration of digital calibrators

GEFRAN LAT 011 laboratory issues calibration certificates for digital calibrators.
A digital calibrator is an instrument that simulates and generates different types of signals. A calibrator can be used both to indicate and to generate temperature values corresponding to different types of thermocouples (J, K, R, S, T, B, N) and of resistance thermometers (Pt100).
When it is equipped with a pressure module, it can be used to read the value of the connected transducer.
On the contrary, the reading of a percentage value is available when the calibrator is connected to a humidity sensor.
If the calibrator is set on temperature and the “IN” function (measuring) is selected, it will work as a common digital thermometer, reading the temperature of the sensor to which it is connected. If it is set on “OUT” (simulation), the calibrator will issue an electric signal corresponding to a selected temperature.
The  certificate shows the signal value traceable to the national standard compared with the corresponding value in °C of the calibrator being calibrated. If connected to pressure and humidity sensors, it will show the corresponding humidity and pressure values.
The procedures applied to carry out the calibration, as filed at LAT-IMGC Head Secretary Office of CNR in Turin, are also listed in the certificate.
The certificate is guaranteed to be always traceable (thanks to a filing system that grants the certificate to be traced at any time after being issued), and acknowledged world-wide by the other National Metrological Institutes, since LAT is one of the Signatories of the “EA” (European Co-operation for the Accreditation of Laboratories).
Among its calibration services, GEFRAN offers the “on-site” calibration, where the calibrator is used as a simulator of temperature signals on digital instruments.
Upon customer’s request, our laboratory can issue a TEST REPORT referred to LAT standards for IN/OUT scales of electrical signals, such as mA, mV and V.
