Martindale EZ165 Socket & Non-Trip Earth Loop Tester

Includes: Martindale EZ165 and user manual.

Reference MAREZ165

Brand Martindale Electric

The Martindale EZ165 is a socket tester that additionally checks the earth loop impedance of the wiring under test and indicates the range that the measured earth loop impedance falls within. If the wiring is faulty or the mains voltage is not within limits the earth loop impedance test is not performed. The EZ165 also indicates if the mains voltage is below 195V or above 270V or if the neutral to earth voltage is greater than 30V.

The EZ165 uses two rows of LED’s to indicate wiring condition, mains voltage level and earth loop impedance. The top row of three tricolour LED’s marked LOOP TEST indicates the range within which the measured earth loop impedance falls.

The bottom row of three tricolour LED’s indicates the condition of the wiring or if the mains supply is <195V or >270V or if the neutral to earth voltage is >30V. The EZ165 must only be used on CAT II installations up to 300V to earth.
