NEVA-TEST 9303
NEVA-Test 9303 reference meter can be used independently, in combination with a PC that expands its functionality, as well as as part of specialized and universal verification installations.
NEVA-Test 9303 reference meter is recommended for use in metrological laboratories of large industrial enterprises, power systems and CSM.
The reference meter NEVA-Test 9303 is a wide-range multifunctional electricity meter of accuracy class 0.02 and is intended for calibration and verification of the following reference and working instruments for measuring electric power quantities:
- single-phase and three-phase meters of active and reactive electrical energy;
- single-phase and three-phase wattmeters, varmeters and measuring transducers of active and reactive power;
- phase meters and frequency meters;
- electrical measuring instruments (voltmeters, ammeters) and measuring voltage and current converters in the industrial frequency range;
- means for measuring and recording the parameters of electrical energy in single-phase and three-phase electrical networks.
FEATURES:
- pulse inputs and outputs have a convenient location for use on the front and rear panels;
- error calculation can be carried out simultaneously on 4 pulse inputs;
- the value of the pulse output constant can be set by the user;
- touch screen for control, convenient and intuitive interface;
- external mouse and keyboard can be used for control;
- Availability of communication ports RS-232, USB and Ethernet.
