B. Safety procedures against unintended use

To ensure your personal safety, please use the test lead that accompanies

the meter. Before operating this meter, ensure that the test lead is

flawless.

1.1.2 Safety considerations

When the meter is used in the vicinity of the equipment that produces

strong electromagnetic interferences, the reading on the meter will grow

unstable and even produce serious errors.

Don't operate the meter or pen-shaped meter whose appearance is

damaged.

The safety function of the meter will become null if the meter is not

properly operated.

The meter must be operated with great care when working in the vicinity

of an exposed conductor or bus line.

The meter is prohibited from being used in the vicinity of any explosive

gas, vapor or dust.

The measurement must be made with correct input terminals and

functions and within the allowable measuring range.

To prevent the meter from being damaged, the value to be input shall not

exceed the extremes allowed by each measuring range.

When the meter has already been connected to the line being measured,

the operator is prohibited from touching the input terminal that is not in

service.

When the voltage measured exceeds 60Vdc or 30Vac (valid value), the

operator shall be careful enough to avoid electric shock.

When making measurement with a test lead, place your fingers behind its

protective ring.

When switching to another measuring range, be sure that test lead has

already been taken off the measured circuit.

For all DC functions, to prevent potential electric shock as a result of

incorrect reading, please first useAC functions to check the absence of

any AV voltage. Then, select DC voltage measuring range equivalent to or

greater than that for AC voltage.

Before the tests on electric resistance, diode, capacitor or continuity, the

operator must cut off the power supply to the circuit to be measured, and

discharge all high-voltage capacitors within the circuit to be measured.

The electric resistance measurement or continuity test cannot be carried

out in any live electrical circuit.

Before the current measurement, the operator must first examine the

protective tube of the meter. Before connecting the meter to the circuit to

be measured, the operator must first power off the aforesaid circuit.

Before repairing TV sets or measuring power switching circuit, the

operator must be careful enough to prevent high amplitude voltage

impulse from damaging the meter.

This meter uses 4 x 1.5V AA batteries that must be correctly installed into

the battery compartment.

When appears, the batteries must be replaced immediately. The low

level of a battery will result in incorrect reading on the meter, which is

likely to bring electric shock or personal injury to the operator.

In measurement, category III voltage and category IV voltage shall not

exceed 1000V and 600V respectively.

Themetershallnot be in service ifits case(or partof itscase)is dismantled.

3.2 Measurement guidelines

3.2.1 Measurement of AC voltage and DC voltage

To avoid any electric shock and/or damage to the meter, do

not attempt a voltage measurement if the voltage (valid

value) is 1,000V for DC current or 750V for AC current.

To avoid any electric shock and/or damage to the meter,

don't attempt to impose between any public terminal and

ground any voltage whose valid value is over 1,000V for DC

current or 750V for AC current.

The meter provides DC voltage measuring ranges as follows: 600.0mV,

6.000V, 60.00V, 600.0V and 1000V, and AC voltage measuring ranges:

6.000V, 60.00V, 600.0V and 750V.

Measurement of AC voltage or DC voltage

Turn the rotary switch to the position ～V or V.

Connect the test lead in black and test lead in red to COM input socket

and V input socket respectively.

Use another two ends of the test lead to measure the voltage of the

circuit to be measured. (In parallel connection with the circuit to be

measured)

Read the measured voltage value on LCD screen. When DC voltage

measurement is attempted, the display unit will show the voltage

polarity of the circuit connected to the pen-shaped meter in red.

Notes:

Within the measuring range of DC voltage of 600mV and AC voltage of

6V, even if there is no input or no connection to the test lead, the meter

will display some information. In this situation, press short circuit “V－

” and “COM” terminal to reset the meter to zero.

Within theAC voltage function, press the key "SEL" to measure the

frequency of theAC voltage source. Please refer to the relevant part for

frequency measurement.

The value of theAC voltage measured with this meter is True RMS (root

mean square). These measurements are accurate for sine wave and

other waves (without DC offset), square wave, triangular wave and step

wave.

3.2.2 Electric resistance measurement

To avoid the meter or the measured equipment from damage,

do not attempt a resistance measurement unless the operator

has already cut off all power sources for the circuit to be

measured and fully discharged all high-voltage capacitors.

Ohm is the unit of electric resistance ().

The measuring ranges of electric resistance of this meter are 600.0,

6.000k, 60.00k, 600.0k, 6.000Mand 60.00M,

Measurement of electric resistance

1. Turn the rotary switch to the appropriate position.

2. Connect the test lead in black and test lead in red to COM input

socket and V/input socket respectively.

3. Use another two ends of the test lead to measure the electric

resistance of the circuit to be measured.

4. Read the measured electric resistance value on LCD screen.

Notes:

The measured value of the electric resistance of the circuit differs a

bit from the rated value of the electric resistance.

To ensure measurement accuracy, in attempting a low resistance

measurement, first put two pen-shaped meters in short circuit and

capture the resistance reading of these short circuits. Then subtract

the aforesaid reading from the measured resistance.

At 60Mposition, you have to wait a few seconds before the reading

grow stable. This is quite normal for a high resistance

measurement.

When the meter is in open circuit, the display unit will show "OL" that

indicates the measured value is over the measuring range.

3.2.3 Diode test

To avoid the meter or the measured equipment from damage,

do not attempt a diode test unless the operator has already

cut off all power sources for the circuit to be measured and

fully discharged all high-voltage capacitors.

Diode test outside the circuit:

1. Turn the rotary switch to the position .

2. Connect the test leads in black and in red to COM input socket and

V/input socket respectively.

3. Connect the test leads in black and in red to the positive and

negative poles of the diode to be tested respectively.

4. The meter displays the forward bias value of the diode to be tested. If
