1.INTRODUCTION

This meter has been designed and tested
according to CE safety requirements for Electronic
Measuring Apparatus, EN61010-1 and other safety
standards. Follow all warnings to ensure safe
operation.

●Application:

Earth Resistance Tester is used to measure the
ohms(Ω) of an earth grounding installation for
buildings (residential, office, labs, hospitals),
computer server rooms, military installations,
cellular sites, radio and cable towers, etc. It is
used to determine if the earth (or ground) is a
good conductor of electricity.

●Purpose of Earth Groun

(1)Avoid human and animal electrical shock.
(2)Avoid unnecessary property and equipment
damage.
(3)Prevent fire or explosion.
(4)Integrate electrical signal to attain proper
operation or measuring purpose.
(5)Provide a means of dissipation for power
surges cau
and other types of electrical interference.

Warning! Risk of electric shock.

Caution! Refer to this manual
before using the Meter.

3.FEATURES

●Capable of measuring earth voltage.

●2mA measuring current permits earth resistance

tests without tripping earth leakage current
breakers in the circuit under test.

●Battery operated.

●Auto power off function. The timer operates auto-

matically about 3~6 minutes when the "PUSH
BUTTON SWITCH" and "TIMER ON BUTTON"
are pressed at the same time to keep the tester
power on.

●Data hold function.

●Small and light weight.

●Designed to meet EN61010-1 CAT III 200V.

6.MEASURING METHODS

BEFORE PROCEEDING MEASUREMENT, READ
SAFETY NOTES ON PAGE 2.

In proceeding with measurement, if "B"
symbol appears on the display, replace
with new batteries.

●Earth Voltage Measurement:
(1) Connection with test leads:

Connect green, yellow test leads to instrument
terminals E, P with auxiliary earth bars P1,
driven into earth " IN A STRAIGHT
LINE".(Fig.1)

(2) Set the function

press the"PUSH-ON" button and "TIME ON"
button at the same time make certain that the
voltage reading is LESS THAN 10V AC,
otherwise accurate earth resistance
measurement may not be made.

(2) Set the Range Switch to suitable range and
set the function switch to Ω position then press
the PUSH-ON BUTTON and TIME ON BUTTON
at the same time and take the reading on the
display.

WARNING

●When none of E, P and C terminals
connected with test leads, the display shows

7.MAINTENANCE

●Battery Replacement:

When the symbol "B" appears on the display,
replace the batteries as follows :

(1) Disconnect the test leads from the instrument

and turn off the power.

(2) Use a screwdriver to unscrew the screw on

back cover then slide the cover, take out the
batterie
SUM-3.

(3) Place back cover and secure by a screw.

●Cleaning and storage:
(1)
