Energy meter tester and power network parameter meter

  • Product No:Caltest 10
  • Manufacturer: Calmet Ltd.

Caltest 10 is a single phase portable device designed for electricity meter testing on site. It contains: 

• versatility – verification of network connection, power network parameters measuring, energy meter testing with  load changing possibility, • wide range of currents 0.01…3000A with clamps, without necessity of measured circuit opening, 

 • multi-variant data tracing – digital and graphic display, internal memory, local printing, transmission by the interface and analysis on PC computer. 

 

Powering from measuring circuit makes device independent from necessity of using additional supply and phantom load changing function makes independent of meter testing from site load.

Local printing on miniature printer makes possible reporting of measuring results in customer's presence.
