HZ3125 Three-Phase Power Energy Meter Field Calibration Device

Adopt the new hardware and software design, HZ3125 Three-Phase Power Energy Meter Field Calibration Device is small in size & light.

It can simultaneously measure single and three-phase AC voltage, current, frequency, phase, active power, active electric energy etc electrical parameters, compatible with calibrating deviation of various mechanical & electronic electricity meters, testing deviation of voltage meter, current meter, frequency meter and phase meter etc.

Key Features of HZ3125 Three-Phase Power Energy Meter Field Calibration Device

  • Multi-channel Design: The double error test channel can verifythe error of active and reactive power or the error of main and secondary meters simultaneously. Support to measure harmonic of 6 channels 51 times current and voltage of simultaneously.
  • High Stability Measurement: Built-in excellent algorithm that ensures value stability of measuring electric energy deviation under the field harmonic or fluctuation load.
  • Multi-functionDesign: Support word reading error test of power energy meter and replenishment rate test calculation. Small current (0.5mA) can also be real-time hexagonal diagram display and line check. Support TA and TV secondary load test. Support data reading of multi-function meter (such as: Periodic electricity, peak, sharp, flat, valley, etc.). Adaptive Baud rate communicates and the protocol can be upgraded.
  • Miniaturize Design: The deviceand its accessories (clamp transformer, cable, photoelectric  sampler) are miniaturized and easy to carry.
  • Strong Protection Design: Corrosionfree, dust-proof, moisture-proof and electromagnetic shielding design that ensures long-term stability.
  • Remote Control: Remote control or obtain online help through mobile phone / panel computer and other mobile devices.
  • Communication Interface: A variety of communication interfaces (RS232, USB, RJ 45, optional WIFI) enables to communicate with the upper computer management software or marketing system interface, realizing paperless measurement verification management.
  • Super Long Voyage: The instrument has a built-in large-capacity lithium battery which can support the power supply for more than 8 hours.
  • Functional Extension: Could connect to external scanner, keyboard and other devices.
  • Friendly Interaction: Large touch screen design displaysall three-phase electrical parameters, total harmonic content, deviation, hexagonal diagram, parameter settings, line check discrimination. At the same time, support handwritten input in Chinese or English character, graphical interface, it’s easy to operate and provide language customization
  • Large Storage: Support maximumstorage capacity up to 32GB and it can save a variety of electrical measurement data
