INTRODUCTION
Warning
• Read the user manual before operating and
follow all safety information.
• Only use the meter as specied in this user
manual.
• Never use this meter on a circuit with voltages 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.
• Check the rotary range switch and make
sure it is at the correct position before each
measurement.
• Do not perform resistance and continuity
test on a live circuit.
• Use extreme caution when measuring live
systems with voltages greater than 60VDC
or 30VAC.
• Use extreme care when working around
bus bars and bare conductors.
• Do not use the meter in over range/overload conditions (OL).
• For accurate readings, change the battery
when the symbol appears.

1.1 International Electrical Symbols
This symbol signies that the instrument is
prtected by double or reinforced insulation.
WARNING - refer to this manual for instructions
before operating the instrument. This symbol
indicates that if the instructions are not followed,
bodily injury, installation/sample and product
damage may result.
Risk of electric shock. The voltage at the parts
marked with this symbol may be dangerous.
Do not operate within external low frequency
magnetic elds >30A/m.
1.2 Receiving Your Shipment
Upon receiving your shipment, make sure that the
contents are consistent with the packing list. Notify
your distributor of any missing items. If the equipment
appears to be damaged, le a claim immediately with
the carrier and notify your distributor at once, giving a
detailed description of any damage. Save the damaged
packing container to substantiate your claim.

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 multiconductors. 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.
