2.1 Description
The TRMS Clamp-on Meter Model 565 is designed to
measure low AC currents, which are typically leakage cur-
rents in ground conductors. Low currents are measured
on the 60mA and 600mA ranges. Note the high sensitivity
of the probe: 10µA and 100µA. This is possible through
special jaw construction and in particular critical shield-
ing of the jaws. At low measurement levels, shielding out
noise is critical for low sensitivity, accuracy and stability.
Leakage current may be measured on a ground conduc-
tor and through the vector sum on multi-conductors. On
a grounded system, clamp around the two or three con-
ducting legs (not the ground conductor). The vector sum
of the load currents will cancel out, leaving the leakage
current measured.
The user may also use the Model 565 as a standard
clamp-on meter to 100A

ranges, resistance and continuity with a buzzer. In mA
AC
and A
, the user can activate a low-pass filter to ignore
AC
all currents other than 50/60Hz. In this mode, only the
fundamental signal is measured. The difference between
the full frequency signal (WIDE displayed on LCD) and
Filtered mode (50/60Hz displayed on LCD) essentially
corresponds to the current attributable to Harmonics.
The Model 565 is ergonomic in design and fits well in the
hand. Also, one hand operation is possible. The jaw size
is compact yet designed to accommodate most known
ground conductors up to 1" (26mm) in diameter.
