ON position. Press the Class I test button to start a Class I test sequence. The PAC3760 plus II will now test the continuity of the protective earth. If the measured value is greater than the 1 ohm pass/fail threshold, the measured value is displayed and the unit indicates a fail result as shown below.
Visually inspect the appliance as per requirements of AS/NZS 3760:2010. If the appliance passes a visual inspection proceed with the electrical tests. Plug the mains lead into the PAC3760 plus II and a mains supply socket. When plugging the mains lead into the PAC3760 plus II ensure that the polarity orientation of the connector is correct.

PAC3760 plus II Operating Instructions Battery Check The PAC3760 plus II is powered from a 6 AA cells which are checked before a test is performed. When the battery voltage is low the enunciator is illuminated. The unit will continue to perform within specification for a limited number of tests, dependent upon the type of the batteries fitted.
Fuse The unit is protected by a fuse. If the fuse should blow then the mains tests will not be allowed to start and the PAC3760 plus II will indicate that the mains connection is incorrect. Fuse Replacement Before opening the PAC3760 plus II ensure that all test leads are disconnected.
PAC3760 plus II Operating Instructions Service and Calibration To maintain the specified accuracy of the measurement results, the instrument must be recalibrated at regular intervals by either the manufacturer, Emona Instruments or by Electrotest Ltd. We recommend a recalibration period of one year.
