DURING USE

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

When the meter is linked to measurement circuit, do not touch unused terminals

Never use the meter to measure voltages that might exceed 600V above earth ground in category Ⅱ

installations

When the value scale to be measured in unknown before hand, 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 remembers that there may be

high amplitude voltages pulses at test points, which can damage the meter.

Always careful when working with voltages above 60V dc or 30V ac rms. Keep fingers behind the probe

barriers while measuring.

Before attempting to insert transistors for testing, always be sure that test leads have been disconnected

from any measurement circuits.

Components should not be connected to the hFE socket when making voltage measurements with test

leads. Never perform resistance measurements on live circuits.’

OPERATING INSTRUCTIONS

DC VOLTAGE MEASUREMENT’

1. Connect the red test lead to the “V.Ω.mA” jack and the black lead to the “COM” jack

2. Set rotary switch at desired DCV position, if the voltage to be measured is not known beforehand, set range

switch at the highest range position and then reduce it until satisfactory resolution is obtained.

3. Connect test leads across the source or load being measured.

4. Read voltage value on the LCD display along with the polarity of the red lead connection.

DC CURRENT MEASUREMENT

1. Connect the red test lead to the “V.Ω.mA” jack and the black test to”COM” jack.(For measurement between

200mAand 10A,remove red lead to”10A” jack)

2. Set the rotary switch at desired DCAposition.

3. Open the circuit in which the current is to be measured and connect test leads in series with the circuit.

4. Read current value on LCD display along with the polarity of red lead connection.

AC VOLTAGE MEASUREMENT

1. Connect the red test lead to the “V.Ω.mA” jack and the back test lead to“COM” jack.

2. Set the rotary switch at desired ACV position.

3. Connect test lead across the source or load being measured.

4. Read voltage value on the LCD display.

RESISTANCE MEASUREMENT

1. Connect the red lead to the “V.Ω.mA” jack and the black test lead to the “COM” jack.(The polarity of red lead

is positive“+”)

2. Set the rotary switch at desired ACV range position.

3. Connect test leads across the resistor to be measured and read LCD display.

4. If the resistance being measured is connected to a circuit, turn off power and discharge all capacitors before

applying test probes.

DIODE TEST

1. Connect the red test lead to the “V.Ω.mA” jack and the black test lead to“COM” jack.(The polarity of red

lead is positive“+”)

2. Set the rotary switch at “＋”position.

3. Connect the red test lead to the anode of the diode to be tested and the black test lead to the cathode of the

diode .The approx, forward voltage drop of the diode will be diode splayed. If the connection is reversed,

only figure“1”will be shown.

TRANSISTOR TEST

1. Set the rotary switch at “hFE”, position.

2. Determine whether the transistor under testing is NPN or PNP and locate the emitter, base and collector

leads. Insert the leads into proper holes of the hEF socket on the front panel.

3. Read the approximate hFE value at the test condition of base current 10μAand Vce 3V.

AUDIBLE CONTINUITY TEST

1. Connect red test lead to the “V.Ω.mA”, black test lead to “COM”.

2. Set range switch to “ ” position.

3. Connect test lead to two points of circuit to be tested. If continuity exists. built-in buzzer will sound.

TEMPERATURE MEASUREMENT

1. Range switch to TEMP position and the current room temperature appears on the display with the

character °C.

2. Connect the k type thermoelectric couple to “V.Ω.mA” and “COM” jacks.

3. Connect the object under measurement with the thermoelectric couple carefully.

4. Read the temperature °C on the display.

TEST SIGNAL USE

1. Range switch to position.

2. Atest signal(50Hz or 1000Hz depending on the model of mulita-meter ) appears between “V.Ω.mA” and “COM”

jack. The output voltage is approx. 5Vpp with a certain DC component, so additional insulating capacitor should be

used.

BATTERY &FUSE REPLACEMENT

If “”appears on display, it indicates that the battery should be replaced.

Fuses rarely need replacement and blow almost always as a result of operator’s error.

To replace battery & fuse (200mA/250V) remove the 2 screws in the bottom of the case. Simply remove the old and

replace with a new one.

Be careful to observe battery polarity.

WARNING

Before attempting to open the case, always be sure that test leads have been disconnected from measurement

circuits. Close case and tighten screws completely before using the meter to avoid electrical shock hazard.
