1. SAFETY INFORMATION

This multimeter has been designed according to IEC-1010 concerning electronic measuring
instruments with an overvoltage category (CAT II) and pollution 2.
Follow all safety and operating instructions to ensure that the meter is used safely and is kept in
good operating condition.

1.1 INTRODUCTION

• When using the meter, the user must observe all normal safety rules concerning:

- Protection against the dangers of electrical current.

- Protection of the meter against misuse.

• Full compliance with safety standards can be guaranteed only if used with test leads supplied. If
necessary, they must be replaced with the same model or same electric ratings. Measuring leads
must be in good condition.

-1-

1.2 USAGE

• Never exceed the protection limit values indicated in specifications for each range of
measurement.

• When the meter is linked to a measurement circuit, do not touch unused terminals.

• When the value scale to be measured is unknown beforehand, set the range selector at the
highest position.

• Before rotating the range selector to change functions, disconnect test leads from the circuit under
test.

• When carrying out measurements on TV or switching power circuits, always remember that there
may be high amplitude voltage pulses at test points which can damage the meter.

• Never perform resistance measurements on live circuits.

• Always be careful when working with voltages above 60V dc or 30V ac rms. Keep fingers behind
the probe barriers while measuring.

current.

• For continue protection against fire, replace fuse only with the specified voltage and current
ratings:
F1: F 500mA/250V F2: F 10A/250A

• If any faults or abnormalities are observed, the meter cannot be used and it has to be checked out.

• Never use the meter unless the back cover is in place and fastened fully.

• To clean the meter, use a damp cloth and mild detergent only, do not use abrasives or solvents on it.

3. OPERATING INSTRUCTIONS

3.1 MEASURING VOLTAGE

1. Connect the black test to the COM jack and the red test lead to the V/Ω jack.

2. Set the function switch at V or V ~ range to be used and connect test leads across the source
or load under measurement.

3. Read LCD display. The polarity of red connection will be indicated when making a DC
measurement.

3.2 MEASURING CURRENT

1. Connect the black test lead to the COM jack and the red test lead to the mA jack for a maximum
of 500mA. For a maximum of 10A, move the red lead to the A jack.

2. Set the function switch at µA, mA or A range to be used and push / ~ button to select DCA of
ACA measuring mode.

-11-

3. Connect test leads in series with the load in which the current is to be measured.

4. Read LCD display. The polarity of red lead connection will be indicated when making a DC
measurement.

3.3 MEASURING RESISTANCE

1. Connect the black test lead to the COM jack and the red test lead to the V/Ω jack. (NOTE: The
polarity of the red lead connection is positive “+”)

2. Set the function switch at Ω range to be used and connect test leads across the resistance under
measurement.

NOTE:

1. For resistance above 1MΩ, the meter may take a few seconds to stabilize reading. This is
normal for high resistance measuring.

2. When the input is not connected, i.e. at open circuit, the figure “OL” will be displayed for the over
range condition.

-12-

3. When checking in-circuit resistance, be sure the circuit under test has all power removed and all
capacitors fully discharged.

3.4 CONTINUITY TEST

1. Connect the black test lead to the COM jack and the red test lead to the V/Ω jack. (NOTE: The
polarity of red lead connection is positive “+”)

2. Set the function switch at i position and connect test leads to two points of the circuit under
measurement. If continuity exists (i.e., the resistance is lower than 50Ω), built-in buzzer will
sound.

3.5 TESTING DIODES

1. Connect the black test lead to the COM jack and the red test lead to the V/Ω JACK. (NOTE: The
polarity of the red lead connection is positive “+”)

2. Set the function switch at position.

-13-

3. Connect the red lead to the anode of the diode to be tested and the black lead to the cathode.
Read LCD display to get the forward voltage drop of the diode under testing.

3.6 TESTING TRANSISTORS

1. Set the function switch at hFE position.

2. Identify whether the transistor NPN or PNP type and locate emitter, base and collector lead.
Insert Ieads of the transistor to be tested into proper holes of the testing socket on the front panel.

3. LCD display will show the approximate hFE value.

6. BATTERY AND FUSE REPLACEMENT

If the sign “BATT” appears on the LCD display, it indicates that the battery should be replaced.
Remove screws on the back cover and open the case. Replace the exhausted battery with a new
battery.
Fuses rarely need replacement and blow usually as a result of incorrect use. Open the case as
mentioned above and take the Printed Circuit Board assembly out of the case. Replace the blown
fuse with a proper rated fuse below.
