The verification complex ZM3003

It has:
a wide range of calibrated currents and voltages reproduction;
wide frequency range at alternating current 20Hz – 20kHz;
adjustment of the phase shift angle between current and voltage in the range 0 – 360 °;
high accuracy of reproduction of current, voltage, phase shift angle.
Normal operating conditions:

ambient temperature (23 ± 5) ° C;
the relative humidity of the surrounding air is 30-80 %;
atmospheric pressure 84 — 106 kPa (630-795 mmHg);
supply network voltage (220 ± 4.4) V;
supply network frequency 48 — 62 Hz.

Operating conditions:

ambient temperature from 5 to 40 ° C;
relative humidity up to 80 % at temperatures up to 30 ° C;
atmospheric pressure 84 — 106 kPa (630 — 795 mmHg)
supply voltage (220 ± 22) At a frequency of 48 — 62 Hz;

The additional error in reproducing the voltage and strength of direct and alternating current, as well as the power from a change in the mains voltage by ± 10% of the nominal value of 220 V does not exceed half of the corresponding basic error.
The additional error from the change in ambient temperature for every 10 ° C does not exceed half of the basic error.
The electrical insulation resistance between the power supply circuits of the device and the housing is not less than:
under normal conditions of use – 20 Mohm;
at elevated ambient temperature — 5 Mom.
The device can be used as part of automated measuring systems for various purposes with serial interfaces: RS-232C (EIA-2320) or USB.
