Refer to Figure 1 and to the following numbered steps to
familiarize yourself with the meter's front panel controls
and connectors.
1. Digital Display - The digital display has a 3400
counts LCD readout with 65 segments analog bar
graph, auto polarity, decimal point, 「」
AC, LOΩ, RANGE, HOLD and unit annunciators.
2. Rotary Switch - Select the Function and Range
desired.
3. COM Input Terminal - Ground input connector.
4. V Ω Input Terminal - Positive input connector for
Volts, Ohms and Diode.
5. HA mA Input Termina - Positive input connector for
Amp measurements (up to 320mA).
6. A Input Terminal - Positive input connector for Amp
measurements (up to 20A).
7. Range Switch, (Manual Range) - "Range" switch is
pushed to select manual ranging and to change
ranges. When "Range" switch is pushed once
"RANGE" anunciator on the LCD is appeared.Push
"RANGE" switch to select appropriate range to be
used. Push "RANGE" switch and hold 2 seconds to
return to Autoranging.
8. AC / DC / / Selection Switch - Push the switch
to measure AC Current or DC Current in the current
mode or to measure continuity or diode in /

The meter will automatically shut itself o after
approximately 10 minutes after power on.
The meter can be turned back on by pushing "Power

This instrument has been designed and tested in
accordance with IEC Publication 1010, Safety Require-
ments for Electronic Measuring Apparatus and has been
supplied in a safe condition. This instruction
manual contains some information and warnings which
have to be followed by the user to ensure safe
operation and to retain the instrumnent in safe condition.
1, Before measurement, warm up for at least 60
seconds.
2. When the rotary function selector is changed during
measurement , be sure do so only after removing
the test leads from the equipment.
OPERATION
3-1 Preparation and Caution before Measurement
7
97 EN
1. Connect the red test lead to "µAmA" terminal and
the other (black) test lead to "COM" terminal, or use
the "A" and "COM" terminal in the 20A range.
2. Set function selector rotary switch to "µA" or "mA"
or "A".
3. Measurement of AC current can be performed by
pushing the "AC/DC" switch.
4. Connect the test leads to the circuit to be measured.
3-3 Current Measurement
1. Connect the red test lead to the " V Ω " input
terminal and the other (black) test lead to the "COM"
terminal.
2. Set the rotary function to the ACV or DCV position.
3. Connect the test leads to the device to be measured.
3-2 Voltage Measurements
WARNING
TO AVOID ELECTRICAL SHOCK , HAZARD OR
DAMAGE TO METER , DO NOT A ATTEMPT TO
MEASURE VOLTAGE THAT MIGHT EXCEED 1000
VOLT DC OR 750 VOLT AC . DO NOT APPLY MORE
THAN 1000V DC OR AC RMS BETWEEN THE
COMMON INPUT TERMINAL AND EARTH GROUND.
NOTICE : UNSTABLE DISPLAY MAY OCCUR
ESPECIALLY AT 300mV RANGE , EVEN THOUGH YOU
DON'TPUT TESTED LEADS INTO INPUT TERMINALS.
IN THIS CASE , IF AN ERRONEOUS READING IS
SUSPECTED, SHORT THE " V Ω " TERMINAL AND
THE "COM" TERMINAL, AND MAKE SURE
THE ZERO DISPLAY.
3. If the equipment is used near noise generating
equipment, be aware that display may become
unstable or indicate large errors.
4. Maximum rated voltage to earth for voltage and
current measurements terminals is 1000V AC / DC
CAT. II .
8
97 EN
1. Connect the red test lead to the " V Ω " terminal
and the other (black) test lead to the "COM" terminal.
2. Set the rotary function selector to " " position.
3. Connect the test leads to the circuit to be measureu .
The biszzer will sound if the resistance of the circuit
measured is lower than 30g.
1. Set the rotary switch at " " position.
2. Connect black test lead to "COM" terminal and red
lead to " V Ω " input terminal.
3. Connect test leads to the diode normally the forward
voltage drop of good silicon diode is shown between
400V to 900V. If the diode under test is defective .
"000" (short circuit) or "OL" (non-conductance) is
displayed. Reverse check of diode if the diode under
test is defective ''000" or other value are to be
displayed.
3-5 Continuity Check by Buzzer
3-6 Diode Check
TO AVOID ELECTRICAL SHOCK REMOVE TEST LEAD
BEFORE OPENING THE COVER.
MANTENANCE
WARNING
1. Connect the red test lead to the " V Ω " terminal and
the other (black) test lead to the "COM" terminal.
2. Set the rotary function selector to "Ω" position to
measure the resistance.
3. For correct reading , ensure that the device being
tested contains no voltage.
4. Connect the test leads across the resistor to be
measured. In order to ensure the best accuracy in
measurement of low resistance, short the test leads
before measurement and memory the test probe
resistance in mind. This necessary to subtract for the
resistance of the test leads themselves.
