standard meter test calibration

La description

• Main features:
  • Mainly produced for energy meter manufacturers
  • Suitable for use in product development, product maintenance and debugging of production lines
  • Table source integrated design and built-in 0.*5 standard meter
  • Devices can be hang **6 positions, built-in error processor (3 positions) and can also plug error processor (6 positions)
  • Direct display voltage, current, phase, power factor, power and frequency
  • Power amplifier uses class D amplifier technology with characteristics of high efficiency and low fault output power
  • Perfect protection functions: short-circuit voltage, current open-circuit protection, load overload protection and signal over-voltage protection
  • 6.2 to *1 harmonic test voltage interruptions and drop test and adjustable harmonic amplitude (<*0%)
  • Sub-structure: source and hang rack can be left unattended
  • Single bond can be implemented UL start and stop function
