Emona Instruments PAC3760 Plus II portable appliance and RCD tester

Emona Instruments has released the PAC3760 Plus II portable appliance and RCD tester. Based on the PAC3760 series, it now also includes an in-built isolation transformer which saves costs and reduces equipment weight by eliminating the need to purchase and carry a separate isolation transformer when testing portable RCDs.

The tester conducts earth bond, insulation and polarity tests, as well as leakage current tests for Class I and Class II appliances and leads, and carries out trip time tests of 10 and 30 mA portable RCDs. When used in conjunction with the optional PAC-TPL 3 phase adaptor, the unit can also carry out three-phase leakage testing of 10, 16, 20 and 32 A three-phase appliances.

The unit operates under mains or battery power and is designed with simple six-button operation: Class I, Class II, leakage, 10 mA RCD, 30 mA RCD and three-phase test buttons. Results are displayed as a pass or fail as well as actual readings. Once the user selects the required test, the tester conducts an automatic sequence of tests, eliminating the need for complicated on-screen menus. Other features include automatic sensing of IEC or extension leads which adds a polarity test to the sequence and automatic detection of whether the appliance is switched ‘On’.

The unit is easy to use and suitable for manual testing and tagging applications requiring compliance with AS/NZS3760.
