Portable Three Phase Meter Test Equipment UTI-SR01

In-built Standard Reference Meter (SRM): accuracy class 0.05.

Error test, start test, creep test, dial test..etc.

Measurement of volts, current, p.f., power, frequency, phase angle, harmonic..etc.

Power Source (PS): output 0-360V/phase & 1mA-120A/phase, or depend on client requirement

Linear amplifier.

Can be independent set & output of each phase voltage & current.

Can set phase angle independently.

Meter Rack: three positions are optional.

Automatic control by PC software.

Manual control by touch screen/keypad.
