Overview
The Metrel Installation Tester is designed for compliance testing to the AS/NZ3000 standard. This multifunctional device is suitable for testing appliances and installations, combining the capabilities of 12 instruments into one highly specified tester. Specifically built to meet Australian standards, it provides the ultimate all-in-one testing solution.
Clever accessories, such as the optional 3-phase adaptor kit, allow for easy deployment of the tester in various environments. An optional resistor box (not included) can be connected to the switchboard during installation testing, eliminating the need for lengthy trailing earth leads during outlet socket testing. Built-in thresholds deliver clear results with PASS/FAIL indications in accordance with AS3000 specifications, similar to an appliance tester.
