Earth Leakage Clamp Meter
Multimeters & Clamp Meters
CM67
Display: 4 digit display
AC mA: 0-30-300mA
AC A: 0-30-60A
AC V: 300V, 600V
Accuracy: 2% ± 5 dgts
Dimensions: 212 x 42 x 30mm
Weight: 220g approx
Includes: two 1.5V (AA) batteries,
carrying case, test leads & manual
A very high quality earth leakage clamp meter with
resolution down to 0.01mA and an accuracy of up to
0.05mA. Ideal for identifying appliances or circuits
which are causing RCDs to trip.
Display hold helps use in awkward places. Low pass
filter eliminates frequencies above 150Hz, avoiding
false readings.

The CM50 range of clamps from Martindale combine
outstanding specifications, measuring capabilities and
careful design to provide the most cost effective
clamps available.
The CM54 is a low cost 1000A AC meter with a large
jaw size and voltage and resistance ranges. It is the
ideal basic clamp meter for AC current use and also
has the functions of a standard multimeter.
The Max control allows you to measure the maximum
reading, and the Hold Button freezes the current reading,
which is very useful when working in cramped places.
