          2712 EL   ELCB Testers
          Up To 500mA  
          2712 EL
          FEATURES
           
           2 Lines x 16 characters L.C.D.
           Very low consumption.
           Microprocessor controlled.
           50Hz and 60Hz operation.
           Menu Driven.
           Accurate digital readout of disconnection time.
           Automatic data hold function.
           Over temperature protection.
           Over voltage protection.
           Fuse protection.
           Zero crossing circuitry permit testing at 0 degree or 180 degree.
           Disconnection phase polarity shown on LCD display.
           Auto-off and Off override.
           Polarity trip indicator (positive or negative phase).
           Wiring polarity indicator.
           Measure voltage between line and earth before testing.
           Frequency measurement indication.
            CAT III 300V.
           The 2712 EL is a compact hand held residual current detector, earth leakage circuit breaker or ground fault circuit interrupter tester (designation could be different from country to country), designed to meet international standards of performance and safety.
           This model is used by professioals to obtain accurate values of the protection disconnection time while a selectable fault current is injected to earth (ground).
