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.

3-4 Resistance Measurement

9

97 EN

The meter is powered by one 9V battery. Refer to Figure

2A and use the following procedure to replace the battery;

1. Disconnect the test leads and turn the meter o.

Remove the test leads from the front terminals.

2. Position the meter face down. Remove the three screws

from the case bottom.

3. Lift the end of the case bottom unit it gently unsnaps

from the case top at the end nearest the LCD.

4. Lift the battery from the case top, and carefully

disconnect the battery connector leads.

5. Snap the battery connector leads to the terminals of a

new battery and reinsert the battery into the case top.

Make sure that the battery leads do not become pinched

between the case bottom and case top.

6. Replace the case top and case bottom. Make sure

that all gaskets are properly seated and the two

snaps on the case top are engaged. Reinstall the

three screws.

4-2 Battery Installation or Replacement

Refer to Figure 2B and the following procedure to examine

or replace the meter's fuse:

1. Perform steps 1 though 3 of the battery replacement

procedure.

2. Lift the circuit board from case top. Do not remove the

screws from the circuit bead.

3. Remove the defective fuse by gentry prying one end of

the fuse loose and sliding the fuse out of the fuse holder.

4. Install a new fuse of sare size and rating. Make sure the

new fuse is centered in the fuse holder.

4-3 Fuse Replacement

1. Repairs or servicing not converted in this manual should

only be performed by qualied personal.

2. Periodically wipe the case with a dry cloth and detergent

do not use abrasives or solvents.

5. Make sure that the case top rotary switch and circuit

board switch both are in the OFF position. Notice the

pointing direction of the case top rotary switch and circuit

board switch are not at same direction.

6. Replace the case top and case bottom. Make sure that

all gaskets are properly seated and the battery leads do

not become pinched between the case halves, and the

two snaps on the case top are engaged. Reinstall the
