             This Test Instrument is a combined 3 Phases Presence and Rotation Indicator combined with a 3 Phases Industrial Earth Leakage Tester. When utilized as a 3 Phase Presence and Rotation Indicator, the instrument does not use the batteries and can still be utilized if the batteries are not present or if the batteries are too low.
             The 3 phase Presence and Rotation Indicator which is indise the 6221 EL, takes it's power from the circuit under test. The Earth Leakage can be utilized on a Single Phase (up to 317Vac Line to Earth) or a 3 Phase Powered System (550V line to Lilne or Phase to Phase) with a protective Earth conductor.
             The Earth Leakage requires batteries. When utilized on a single phase ensure correct connection between Line and Earth before using the tester.
             When utilized on a 3 Phase Powered System, the instrument is then utilized as a 3 Phases Presence and Rotation Indicator and a Earth leakage tester (selecting which phase to Earth will be utilized for the ELCB test).
             When utilized on a 3 Phase Powered System, this instrument is a rotary field indicatino instrument which display all three phases by lighting up it's corresponding Lamp. It display the rotation (clockwise or anti-clockwise) on a LED.
             To test the tripping time or the tripping current of a Earth Leakage Circuit Breaker, make sure to connect the earth wire. This instrument represents the quickest and easiest way for servicing, repairing and electrical maintenance of 3 phase system with earth leakage.
             With this equipment, you can, before connecting Load to Supply : on the supply side; Quickly verify the presence of the three Phases on a 3 Phases Power System. Confirm the Phase Rotation on a Powered 3 Phase System. Test the Tripping (disconnection) current and time of the protections.
