Like all other indicators this unit

cannot detect common earth and

neutral or earth neutral reversal.

This is the first socket tester that gives a measurement

of the earth loop impedance. This is the only safe

solution for socket testing, as other testers can indicate

as “safe” a socket with a dangerously high earth

resistance.

Conventional indicators have the weakness that they

only tell if the earth is connected, they don’t indicate

how safe it is.

Martindale’s new T-Safe™ Technology gives safe,

earth loop impedance checking within carefully

selected bands, without tripping the RCDs.

• Non-trip earth loop test

• Voltage test

• Socket test for open termination and correct wires

• T-Safe™ technology

• Identifies faults other checkers can’t

• Patented technology

Professional kit

EZ650

EZ150 Specification: see above

TL88 Specification: see page 63

Includes: mains lead (EX332 13A)

& 3 way fused leads (TL88)

The E-Ze Check™ Pro Kit has an IEC socket with an

interchangeable 3 pin adaptor and TL88 3 way fused

leads with croc clips.

This allows testing at light fittings, distribution boards

and terminals using the same technology as the

E-Ze Check™ described above.

The kit is contained in a custom designed lightweight

protective plastic case complete with carry handle.

• Everything needed for socket testing in one kit

• Comes in a robust, easy to carry case
