Ethos Multi Function Tester


Introducing the new Ethos 7920 Multifunction Tester that has been designed and built to the highest standards providing you with a safe and simple solution to your test requirements.

The 7920 tester is used to verify the safety of domestic, commercial, and industrial installations. All testing is required to meet the current IEE 17th edition of the wiring regulations (BS7671). The 7920 covers all aspects of these requirements with ease of use and safety in mind. Test selection is easy to follow with the large rotary selector and easy to read large display. The F1-F4 keys also keep the type of test you require simple by following the screen selection.

Important: The 7920 provides a special safety feature that allows inadvertent connection to a live circuit when performing a “dead” test by operating a warning system on the instrument both visual and audible so the user is made aware of their mistake. In addition to this, a safety cut-out will operate and ensure that no damage is caused both to the instrument and the user.

The following tests are available:

■Voltage and frequency
■Insulation resistance
■Continuity (visual/audible)
■Low ohm resistance
■RCD ramp test
■Phase rotation test
■Earth loop impedance (with no-trip facility)
■RCD testing (with auto test facility)
■Safety cut out if connected to a live circuit on dead testing
■Safety cut out if connected to a 3 phase supply
■Complete with a switch probe
■Rubber protected surround
■Large carry case to hold all the test leads
■Auto testing on loop, RCD, low Ohm, continuity
■3 year warranty
■Full calibration certificate
