M-142 Multifunction Calibrator 15 ppm

Calibratore multifunzione M-142

Multifunction calibrator M-142 is calibrator of electric quantities for application in calibration laboratories and in production lines where meters are manufatured. It can be used for calibration and adjustment of meters from the field of voltage, current, resistance, capacity and frequency. Installed harmonic and non-harmonic shape signals as well make it possible to test parameters of the meters by a signal with various crest factor. Frequency modes enable to set frequency, amplitude and duty ratio of the output signal. They are suitable for basic calibration of oscilloscopes. The calibrator is equipped with possibility to measure temperature with TC and RTD temperature sensors. Built-in multimeter can be used independently or in simultaneous operation with source part of the calibrator together. Testing of transducers of various types, regulators and evaluating units can be perform with it without necessity to use any other measuring instrument.

M-142 multifunction calibrator is available in bench-top and in 19" rack housings.

Basic parameters

Basic function of the calibrator is generating of the calibrated DC/AC voltage in the range from 0 µV to 1000 V and DC/AC current in the range from 0 to 30 A . Using a 50-turn coil the current range can be extended to 1500 A. The best accuracy of the calibrator on DC voltage ranges is 15 ppm, on AC voltage ranges 250 ppm, on DC current ranges 130 ppm and on AC current ranges 550 ppm. Maximum frequency range is from 20 Hz to 100 kHz for harmonic output waveform. The calibrator is equipped with the function of generation the periodic non-harmonic signals with the defined crest factor. Thus it makes possible to test sensitivity of multimeters to distorted signals. Next function of the calibrator is simulation of resistance and capacity. With the calibrator, the resistance in range from 0 Ohm to 1000 MOhm and capacitance from 1 nF to 100 µF can be simulated with the enough precision for calibration of common used hand-held multimeters. Basic accuracy of the resistance ranges is 150 ppm%, of the capacitance ranges it is 0.1%.

Frequency function of the calibrator makes it possible to generate a square wave signal with adjustable and calibrated duty ratio, frequency and amplitude in range from 1 mV to 10 V in the frequency band up to 10 kHz. In the mode HF the square wave signal up to 20 MHz with a very low risetime can be generated. The frequency functions are suitable for the calibrations of corresponding frequency ranges of the multimeters, and for calibration of the channel sensitivities and time bases of the oscilloscopes as well.

For calibrations of DC and one-phase AC power-meters and energy meters, the power – energy mode is determined. Output voltage can be set up to 240 V and output current up to 20 A with the power factor in range from -1 to +1 in the frequency band from 40 Hz to 400 Hz. Current capability of the voltage output is 30 mA. It allows to calibrate also analogue power-meters which has usually higher consumption. For calibrations of the thermometers and temperature regulators, the function of simulation of temperature sensors is determined. Calibrator is able to simulate all common used Pt and Ni resistance sensors and TC sensors of the R, S, B, J, T, E, K and N types as well. Compensation of the TC cold junction is made either by entering value from the keyboard, or automatically by measuring the ambient temperature with Pt-100 sensor. The precision of the simulated resistance and TC sensors depends on set value and type of the sensor. For resistance sensors uncertainty band is in the range from 0.04 °C to 0.5 °C, for TC sensors from 0.4 °C to 4.0 °C.

Build-in multimeter

Internal multimeter with basic capability to measure DC current to 20 mA,DC voltage to 10 V, resistance to 2 kOhm and frequency to 15 kHz is standard part of the calibrator. With accuracy of 100 ppm it enables to measure output signals of various types of transducers. With external TC or resistance temperature sensor temperature can be scan and similarly, with external strange gauge sensorspressure, torsion, strength, etc. can be measured and displayed.

Calibrator – Tester

Calibrator can be used in simultaneous mode, i.e. selected output signal is generated and the response of the device under test is measured at the same time by internal multimeter. Programmable capability of the calibrator enables setting of 10 steps defined by output signal function and output value on source side and awaiting response of DUT measured by internal multimeter including allowed limits of the DUT. The testing can run automatically.

User comfort

M-142 Calibrator is equipped with a number of other functions which make its use easier. Among them belong possibility to set relative deviations from the actual value of the selected output signal, displaying of the output signal uncertainty, internal calibration procedure and others. Concept of the calibrator's control and indication uses a large area luminescence display on which all necessary information is concentrated. The control is perform by selection from the menu. Moreover, frequently used functions have firmly assigned keys with direct control. Normally, the calibrator is equipped with the GPIB bus and with the RS-232 serial port making it possible to be controlled by personal computer.

The calibrator can be included into MEATEST WinQbase/CALIBER software calibration systems.

M-142 calibrator is derived from previous successful model M-140. Against M-140 model the M-142 new one offers extended ranges and higher accuracy.
