not connected to a device, the display may show a random,

changing reading. This is normal and is caused by the high-input

sensitivity. The reading will stabilize and give a proper measurement

when connected to a circuit.

DATA HOLD BUTTON

The Data Hold function allows the meter to "freeze" a measurement

for later reference.

1. Press the DATA HOLD button to "freeze" the reading on the

indicator. The indicators "HOLD" will be appear in the display.

2. Press the DATA HOLD button to return to normal operation.

BACK LIGHT BUTTON

The BACK LIGHT BUTTON is used to turn the back light on Only. To

extend the battery life, The back light will be turned off automatically

within around 3 seconds

DC VOLTAGE MEASUREMENTS

CAUTION:

Do not measure DC voltages if a motor on the

circuit is being switched ON or OFF. Large voltage surges may

occur that can damage the meter.

Set the function switch to the V DC position ("mV" will appear in

function when making

SWITCH , "

" will be

the display).

2. Insert the black test lead banana plug into the negative (COM)

jack and the red test lead banana plug into the positive (V) jack.

3. Touch the test probe tips to the circuit under test. Be sure to

observe the correct polarity (red lead to positive, black lead to

negative).

4. Read the voltage in the display. The display will indicate the

proper decimal point and value. If the polarity is reversed, the

display will show (-) minus before the value.

AC VOLTAGE MEASUREMENTS

WARNING: Risk of Electrocution. The probe tips may not be

long enough to contact the live parts inside some 240V outlets

for appliances because the contacts are recessed deep in the

outlets. As a result, the reading may show 0 volts when the outlet

actually has voltage on it. Make sure the probe tips are touching

the metal contacts inside the outlet before assuming that no

voltage is present.

CAUTION:

Do not measure AC voltages if a motor on the

circuit is being switched ON or OFF. Large voltage surges may

occur that can damage the meter.

1. Set the function switch to the V AC position.

2. Insert the black test lead banana plug into the negative

(COM) jack and the red test lead banana plug into the

positive (V) jack.

3. Touch the test probe tips to the circuit under test.

4. Read the voltage in the display. The display will indicate

the proper decimal point, value and symbol (AC, V, etc.).
