4.1. 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.

4.2. 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 on

the display).

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

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

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).

Read the voltage on the display. The display will indicate the

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

display will show (-) minus before the value.

4.3. 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 0V 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.

Set the function switch to the V AC position.

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

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

Touch the test probe tips to the circuit under test

Read the voltage on the display. The display will indicate the

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