I. Safety Precautions And Procedures

This instrument was designed in compliance with IEC1010-1& IEC1010-2-032
safety guideline relative to electronic equipment.
For your own safety and to avoid damaging the instrument you are
recommended to follow the procedures described in this manual and read
carefully all instructions preceded by this symbol

Before and during measurements keep to the following instructions:

● Do not take current measurements in wet places

● Do not take the measurements in the presence of explosive gas and

combustibles or in dusty places

● Avoid any contact with the circuit under test even though you are not
taking any measurement

● Avoid any contact with exposed metal parts, unused measuring terminals,
circuits etc. Do not take any measurement whenever anomalous conditions
occur such as deformations, breaks, leakages, blind display etc

The herewith symbols are used in this manual and on the meter

CAUTION: refer to the instruction manual. An improper use may

damage the instrument or its components as well as endanger the user.

High voltage danger: risk of electric shock

1. Preliminary Instructions

● This instrument has been designer for use in environments with pollution
degree 2

● It can be used for voltage and current measurements on electrical
installations with overvoltage CAT III 600V

● You are recommended to respect the usual safety regulations aimed at
protecting you against dangerous current and protecting the instrument
against improper use

● Only the original accessories supplied along with the instrument guarantee
compliance with the safety standards in force. They must be in a good
conditions and, if necessary, replaced with identical ones

● Do not test nor connect to any circuit exceeding the specified overload
protection

● Do not take measurements under environmental conditions exceeding the
limits indicated in this manual

● Make sure that batteries are correctly installed

2. During Use

You are recommended to read carefully the following instructions:

CAUTION

Failure to comply with warnings and instructions may damage the
instrument and/or its components as well as injure the operator

● Do not measure in the presence of external voltages. Although the
instrument is protected, an excessive voltage may cause malfunction

● Avoid submitting the instrument to voltage while measuring (i.e. a test lead
slipping off the measuring point accidentally touching an energized point)

-2-

CAUTION

If the “low battery” symbol is displayed during use
interrupt testing, switch off the instrument and replace batteries.

u (Take note of the polarity when replace the battery.)

3. After Use

● Turn off the instrument pressing ON/OFF key after using it

● If you expect not to use the instrument for a long time remove batteries

II. Introduction

ETCR7100 series of Super-large Caliber Leakage Clamp Meter is well
designed and manufactured for measuring AC leakage current, current,
voltage, adopt the latest CT technology and digital integrated technology. Its
large caliber 108mm×148mm can clamp electric cable of 108mm diameter, or
160mm×4mm flat cable and steel earth wires. It is suitable for leakage current
measurement of cable and transformer earth steel. Full automatically and
LCD display, all the data are displayed in the screen, which is very clear and
convenient. The meter is widely used in electric power, communication,
meteorology, railway, oil field, architecture, measuring, teaching research unit,
industrial mining enterprises, etc.

ETCR7100 series of Super-large Caliber Leakage Clamp Meter’s
clamp core is made of special alloy, adopt the latest magnetic shielding
techniques, to ensure the high precision, high stability and high reliability of
perennial uninterrupted measurement. The meter can store 99 sets of data,
with RS232 interface, upload stored data to the computer through the system
software, implementing online real-time monitoring, historical inquires,
