ZERA MT680s Single-phase Test System

Single-phase Test System with Integrated Current Source

Açıklama

OLYMPUS DIGITAL CAMERA

The state of the art test system MT680s consists of a class 0.1 reference meter with built-in current source (up to 120 A). The system is particularly designed for analysis of complete metering installations and local mains conditions. The equipment offers high functionality combined with an excellent menu guided operation via colored 6.5” touch screen or externally via interface.

Features

  • Testing meter installations in two-wire systems
  • Power and energy measurements for active, reactive and apparent power
  • Measuring frequency, phase shift and power factor
  • Harmonic spectrum analysis for voltage and current up to the 40th order
  • Measuring the distortion factor
  • Vector representation of the measuring values
  • Oscilloscope function for curve scanning
  • Energy dosing with built-in current source
