Safety Information

Follow operating instructions carefully.

Electrical Shock Hazard.

Contact with live circuits will result in severe injury

or death.

A person who has not read and does not understand all

operating instructions is not qualified to operate this

tool.

Failure to read and understand safety instructions may

result in severe injury or death.

• Do not use meter if it is wet or damaged. Electric shock or damage to meter

may result.

• Do not perform any service or maintenance other than that described in

these instructions. Electric shock or damage to meter may result.

• Do not touch probe ends. Electric shock may result.

• Do not attempt to measure uninsulated conductors having a voltage greater

than 600V AC/DC. Electric shock or damage to the meter may result.

• Do not connect a source of voltage with the Range Selector Switch in the Ω

(ohms) position. Personal injury or damage to meter may result.

• Turn meter OFF and remove it from the item being tested before replacing

battery. Do not use meter until the back is in place and fastened securely.

Failure to observe these warnings may result in severe injury or death.

• Replace a weak or discharged battery as soon as it is detected. Incorrect

results may occur.

• Do not use or store this instrument in a high temperature or high humidity

environment. (Operating range: 0°~ 45°C, less than 75% R.H.)

• Do not store the meter in direct sunlight.

• Remove battery before storing meter.

Failure to observe these precautions could result in injury or property

damage.

2 500 2280.6 Carrying Case

3 500 2096.0 Test Lead Set

4 — 9V Battery

Features (Figure 1)

(1) Digital Display — The digital display has a 3-3/4 digit LCD readout

(maximum reading 3999) plus auto polarity, decimal point, over-range

indication (“OL”), low battery indication, AC and unit icons.

(2) Input Terminals — The black test lead is always connected to the “COM”

input terminal and red test lead is always connected to the “V - Ω” input

terminal when measuring ACV and OHMS.

while in use.

(4) Function Switch — Slide switch to turn on meter and select V, A or

Ω, function.

(5) Data Hold Switch — Used to hold measured value for all functions.

(6) Trigger — Press the lever to open the jaws. When the pressure on the lever

is released, the jaws will close again.

(7) Jaws — Senses

the current

flowing through

the conductor

under test.

(8) Hand Guard —

Designed to

protect user.

Operation

AC Current Measurement

Electrical Shock Hazard.

Contact with live circuits will result in severe injury

or death.

1. Set the slide switch to the “A” position.

2. Press the trigger to open the jaws. Clamp around one conductor only.

Make sure that the jaws are firmly closed around the conductor.

3. Read the value from the digital display.

AC Voltage Measurement

Electrical Shock Hazard.

Contact with live circuits will result in severe injury

or death.

1. Set the slide switch to the “V” position.

2. Connect the black test lead to the COM terminal and the red test lead to the

V - Ωterminal.

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

4. Read the value from the digital display.

Resistance Measurement

Never connect a source of voltage with the Range Selector Switch in the

Ω(ohms) position. Personal injury or damage to the tester may result.

Failure to observe this warning can result in severe injury or death.

1. Turn off device to be tested. Discharge any capacitors. Voltage should not

present.

2. Slide switch to the Ωposition.

3. Connect the black test lead to the COM terminal and to red test lead to the

V - Ωterminal.

4. Connect test leads across the resistance being measured. The resistance value

will appear on the display.

Note: Resistance reading should always be taken in parallel with the circuit.

The built-in buzzer sounds if the resistance of the tested circuit is less than 100Ω.
