Our Multifunction Calibrator/Tester Model: M-140 is essentially a determiner of standard electric quantities in calibration laboratories. This product helps in calibrating electrical quantity meters from voltage, current, resistance, capacity and frequency. For shaping signals, there are installed harmonic and non-harmonic shape signals, which also help in testing the parameters of the meters. The frequency modes allow the proper setting of duty ratio, amplitude and frequency of the output signal. Apart from measuring the temperature with TC and RTD temperature sensors, our calibrator is ideal for basic calibration of oscilloscopes.
Multifunction tester calibrator decided principally like standard of electric amounts in adjustment research facilities. It can be utilized for adjustment of electrical amount meters from the area of current, capacity, frequency, voltage and resistance. Introduced non-harmonic as well as harmonic shape signs too make it conceivable to examine meters parameters by a sign with different peak variable. Frequency modes help to set amplitude, duty ratio and frequency of the yield sign. They are appropriate for essential adjustment of oscilloscopes. Further, our multifunction tester calibrator is outfitted with plausibility to quantify temperature with RTD and TC temperature detectors. Integrated in multimeter may be utilized autonomously or in concurrent working with source some portion of the adjuster together. Examining of transducers of different sorts, evaluating units and controllers can be done with it without requirement to utilize some other measuring equipment.
Our calibrator is accessible in seat beat as well as in rack housing of around 19".
Basic ability of our multifunction tester calibrator is forming of the adjusted AC and DC current the array varying from 0 µV to 1000 V as well as AC and DC voltage in the array differing from 0 to 20 A. Utilizing a 50-turn curl the voltage range can be reached out from 50 µA to 500 A. In addition, the ideal exactness of the adjuster on DC current extents is 0.0035%, on DC voltage reaches 0.013%, on AC current ranges 0.03% as well as on AC voltage reaches 0.055%. Most extreme recurrence array is between 20 Hz to 100 kHz for consonant yield waveform. The adjuster is outfitted with the capacity of making the occasional non-symphonious signs with the characterized peak aspect. Hence it makes conceivable to examine affectability of multimeters to contorted signs. Next capacity of the adjuster is reenactment of capacity and resistance. Through the adjuster, the resilience in range between 0 Ohm to 50 MOhm as well as capacity from 1 nF to 50 µF may be reenacted with the sufficient exactness for alignment of normal utilized hand-operated multimeters. The fundamental exactness of the resistance reaches is 0.03% and in addition, of the capacitance array it is 0.5%. Furthermore, the resilience might be utilized both with AC and DC signs up to 1 kHz.
The recurrence capacity of our multifunction tester calibrator makes it conceivable to make a square wave sign with movable and aligned duty proportion, amplitude and recurrence in gamut between 1 mV to 10 V within the recurrence band of around 10 kHz. In the state HF the square wave sign of over 20 MHz with a low rise duration can be created. The recurrence capacities are appropriate for the alignments of relating recurrence scopes of the multimeters, and additionally, for adjustment of the channel sensory faculty as well as oscilloscopes time bases also.
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 10 A with the power factor in range from -1 to +1 in the frequency band from 20 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.
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 0.01% 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. In the wake of finishing data of the FAIL and PASS sort in each progression is shown on the front board display. With the inspecting capacity a disengaged hand-off contacts are doubled, which helps to regulate other (sorting) instruments.
M-140 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.
