Caltest *0 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.*1…***0A 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 customers presence.

Verification of power network connection with measuring of voltage, current, active and reactive power, phase shift, power factor and frequency.

 Energy meter testing on site functions of computing meter error directly in percentages with method of setting time of measurements or number of impulses. S0 standard is used for testing energy meters with impulse output. Miniature photo head CF**1 is used for automatic counting of meter rotor turns for testing Ferrari meters. Photo head CF**0 is used for automatic testing of meters with LED indicator and manual counting of rotor turns with using "start/stop" .

 Energy meter counters testing functions of energy measuring in defined period of time and counters error calculating, directly in percent.
