CHAPTER 1

INTRODUCTION

Warning

• Read the user manual before operating and

follow all safety information.

• 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.

• 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/over-

load conditions (OL).

• For accurate readings, change the battery

when the symbol appears.

1.1 International Electrical Symbols

This symbol signies 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.

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.
