I .SAFETY INFORMATION

• Read the following safety information carefully before

attempting to operate or service the meter.

• To avoid damages to the instrument, do not exceed the

maximum limits of the input values shown in the technical

specification tables.

• Never measure current while the test leads are inserted

into the input jacks.

• Do not use the meter or test leads if they lock damaged.

Use with extreme caution when working around bare

conductors or bus bars.

• Accidental contact with the conductor could result in

electric shock.

• Use the meter only as specified in this manual; otherwise,

the protection provided by the meter may be impaired.

• Read the operating instructions before use and follow all

safety information.

• Be cautious when working with voltages above 6OVDc or

4-7 Diode test / Continuity Measurement

WARNING

Before taking any in circuit resistance

measurement, remove power from the circuit

being tested and discharge all capacitors.

(I) Diodes test

1. Connect red test lead to the "+" terminal and black test

lead to the "COM" terminal.

2. Set range switch to the diode test position " ".

3. Connect the red test to the anode side and black test

lead to the cathode side of the diode being tested.

4. Read forward voltage (V ) value on LCD.

If the test lead is connected rather than procedure (3),

the digital reading should nearly equal to the reading in

the open circuit condition. This can be used for

distinguishing anode and cathode poles of a diode.

IV .OPERATING INSTRUCTION

4-1Measurement Procedure operating instructions

1) Make sure that the selected range is suitable for the

measurement to be taken.

2) If the current under measurement is higher than the

selected value for a long period, overheating may take

place, compromising the safety and operation of inner

circuits.

3) Do not measure currents on high voltage conductors

(>1000VDC or 750VAC) to avoid risks of discharge

and/or incorrect readings.

4-2 AC Current measurements

WARNING

Make certain that all test leads are disconnected

from the meter terminals.

1. Set the function/range switch to the A range.(40 — A .

400—A or 1000—A)

2. Clamp the sensor jaw around one of the conductors

under test. Make sure that the clamp jaw be perfectly

closed.

3. Read the displayed value.

4-3 DCmV Voltage Measurements

1. Set the function switch to the DCmV range.

2. Connect the black and red test leads to the COM and +

terminals respectively.
