1. INTRODUCTION
1.1 Inspection
Examine the shipping carton for any sign of damage. Inspect the
unit and any accessories for damage. If there is any damage then
consult your distributor immediately.
1.2 Description
The E-Ze Check™ Xtra 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 the earth loop impedance test is not performed.
The E-Ze Check™ Xtra will also indicate if the mains voltage is below
195V or above 270V.
The 'T Safe' technology employed by the E-Ze Check™ Xtra allows
the earth loop impedance to be measured with a 30mA or higher
RCD in circuit without it tripping.
The E-Ze Check™ Xtra Professional Kit is supplied with both a 13A
3 pin adaptor and a flying lead with croc clips which can be used at
junction boxes and terminals where there is only access to bare wires.
1.3 Earth Loop Impedance
Health and Safety regulations require that electrical installations be
periodically checked for satisfactory operation, and for electricians to
work to the British Standard BS7671, which lays down a schedule
for such testing.
