• Only use the meter as specied in this user
manual.
• Never use this meter on a circuit with volt-
ages greater than 600Vrms @ 50/60Hz.
• Never measure current while the test leads
are connected to the input jacks.
• Do not operate the meter if the case or
tests leads look damaged.
• Only use factory supplied leads.

CHAPTER 2
PRODUCT FEATURES
2.1 Description
The TRMS Clamp-on Meter Model 566 is designed to
measure low AC currents, which are typically leakage
currents in ground conductors. Low currents are
measured in the 60mA and 600mA ranges. Note the high
sensitivity of the probe: 1uA, 10uA, and 100uA resolution
when measuring mA. This is possible through special
jaw construction and in particular critical shielding 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
conductor and through the vector sum on multi-
conductors. On a grounded system, clamp around the
two or three conducting legs (not the ground conductor).
The vector sum of the load currents will cancel out,
leaving the leakage current measured.
You can also use the Model 566 as a standard clamp-on
meter to 60Arms, plus standard VAC, VDC ranges,
resistance and continuity with a buzzer. In mAAC and
AAC, the user can activate a low-pass lter (LPF) to
ignore all currents other than 50/60Hz. In this mode, only
the fundamental signal is measured.
The Model 566 is ergonomic in design and ts 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 0.91" (23mm) in diameter.

2.4 Button Functions
2.4.1 HOLD / LPF Button
This button has two functions, HOLD and LPF (Low
Pass Filter).
HOLD
This function locks (holds) the measurement currently
displayed on the LCD.
1. To activate, press the HOLD button during the
measurement. The HOLD symbol appears and the
measurement is locked.
2. To deactivate, press the HOLD button again.
LPF (Low Pass Filter)
The cut-o󰀨 frequency of the low pass lter is approxi-
mately 60Hz with an attenuation characteristic of
approximately -24dB/octave.
1. To activate the LPF feature, press and hold down the
HOLD button for approximately 2 seconds until the
symbol appears on the LCD.
2. To deactivate, press and hold down the button again
for approximately 2 seconds. The meter will return to
normal operation mode.
Note: This feature is active when the rotary switch is set
to AAC or mAAC.
2.4.2 PEAK / Ω Button
1. Press the PEAK button to enter PEAK mode. In this
mode the instrument records the peak maximum
value. Press PEAK again to return to normal mode.
2. With the rotary switch set to Ω, press PEAK to
enter resistance measurement mode. Press PEAK a
second time to enter continuity test mode.

Clamp-on Meter Model 566 7
2.4.3 ZERO (Relative) Button
This function can be used to compare two voltage
measurements (e.g. to determine a voltage drop) or to
compensate for the resistance of the leads when making
low resistance measurements.
1. Press the ZERO button to enter Zero mode. The
ZERO symbol appears on the display. The reading
is stored as a reference value for subsequent
measurements.
2. To exit Zero mode, press the ZERO button again.
2.4.4 Backlight Button
Press the button to turn the backlight on. Press it
again to turn it o󰀨. When the backlight is on, the meter
will automatically turn it o󰀨 after about 30 seconds.
2.4.5 Auto-OFF
The Model 566 will automatically shut down if there is no
activity for approximately 30 minutes.
1. To disable the Auto-OFF function, turn the rotary
switch to OFF.
2. Press and hold down the HOLD button and set the
rotary switch to any position other than OFF.
3. The symbol disappears and the Auto-OFF
feature is deactivated.

4.2 AC Current Measurement
Remove test leads before measuring current.
1. T urn the rotary switch to the
A
or
mA
setting.
The current to be measured should fall within the
selected range .
2. To make a normal current measurement, press
the jaw trigger to open the clamp meter jaws and
close them over one conductor only. The measured
current value appears on the LCD. Earth leakage
current or any small AC current that ows through a
ground wire can also be measured by this method.
3. To freeze the reading, push the HOLD button. Push
the button again to release.
Immediately unclamp the meter from the
conductor if " " is displayed.
