Mains supply: 200-250V(30-70Hz)
Power consumption: <1.2W
Temperature range: -10°C to 40°C
60% RH (max)

Like all other socket testers these
units cannot detect common earth
and neutral or earth neutral reversal.
The check plug is a fast and easy way to ensure that
13A sockets are wired correctly, indicated by all three
high brightness, long life, neons illuminating.
Wiring errors are indicated by one or more neons
failing to light, with the pattern of lit neons indicating
the type of fault. This failsafe system means that any
neon not lit indicates a problem.
The unit has a virtually indestructible, flame retardant
ABS case with a sculpted shape for easy removal. The
plug induces less than 5mA of earth leakage, well
below RCD trip thresholds.
As with all socket testers the plug only verifies the
presence of an earth, it does not assess its quality.
See page 39 for the Martindale E-Ze Check™ Xtra
Earth Loop Impedance Socket Tester, which checks
earth quality. Detects 14 different fault types.
Buzz - IT Check Plug with sounderBZ101
Mains supply: 200-250V, (30-70Hz)
Power consumption: <1.5W
Temperature range: -10°C to 40°C
at 60%RH (max)
Earth leakage: <5mA
Overvoltage: CAT II/300 V
Housing: Flame retardant ABS
Dimensions: 65 x 65 x 47mm
This plug is a fast and easy way to ensure 13A sockets
are wired correctly in the same way as the classic
check plug above. The Buzz It gives an audible signal
in addition to the three neons lighting when the wiring
is correct. This allows for awkwardly placed, or not
easily visible, sockets to be checked quickly.
It can also be used as a basic fuse finder - when the
correct fuse is pulled the buzzer stops! (For a more
sophisticated fuse finder, with no hearing distance
limits & no risk of pulling the wrong fuse, see pages 46
& 47). Detects 14 different fault types.
A range of Martindale international
check plugs is also available,
supplied with adaptors allowing use
on a wide range of sockets.
