Introduction
The MC 75.2 is a multifunction calibrator. It is specially designed for calibration and mainte-
nance and can measure and simulate physical and electrical quantities, either on site or in
the laboratory.
It can perform all the following functions:
•
Measure DC voltage and current, resistance and frequency / counts and pressure.
•
Measure temperatures using thermocouples and resistive probes.
•
Supply power and measure a current loop which is compatible with the HART
®
protocol.
•
Generate DC voltages and currents.
•
Simulate resistance, thermocouples and resistive probes.
•
Recording of measurements and their display as a table or trend curve.
•
Calibration and generation of the calibration report.
•
Possibility of using calibrated sensors with memorisation of the calibration factors.
Measurement and transmission can take place simultaneously, with a double display.
In particular, it can calibrate air conditioning systems or transmitters by generating a signal
at the input to simulate a sensor and measuring the conversion current or voltage. Internal
software facilitates this operation, but it is also useful in other applications, notably in moni-
toring changes in physical quantities during processing, transformation phenomena, heat ex-
change, etc., either in development or quality testing.
The MC 75.2 has many associated functions that extend its range of application:
•
Relative measurement.
•
Results displayed based on a linear or other conversion law.
•
Generation of increments and simple or cyclic ramps.
•
Synthesis of curves.
A number of improvements have provided it with:
•
Rapid access to all its functions.
•
Intuitive user interface.
•
Advanced on-line help system.
•
Multi-functions keys defined step-by-step on the display.
•
Connections which can be made with 4 mm safety plugs.
•
Protection against overloads.
•
Powered by a rechargeable battery with rapid internal charger.
The unit is enclosed in an ABS case with rubber sheath.
