SAFETY INFORMATION
The following safety information must be observed to ensure
maximum personal safety during the operation of this meter:
Do not use the meter if the meter or test leads look
damaged, or if you suspect that the meter is not
operating properly.
Never ground yourself when taking electrical
measurements. Do not touch exposed metal pipes,
outlets, fixtures, etc., which might be at ground potential.
Keep your body isolated from ground by using dry
clothing, rubber shoes, rubber mats, or any approved
insulating material.
Turn off power to the circuit under test before cutting,
unsoldering, or breaking the circuit. Small amounts of
current can be dangerous.
Use caution when working above 60V dc or 30V ac rms.
Such voltages pose a shock hazard.
When using the probes, keep your fingers behind the
finger guards on the probes.
Measuring voltage which exceeds the limits of the
multimeter may damage the meter and expose the
operator to a shock hazard. Always recognize the meter
voltage limits as stated on the front of the meter.
Never apply voltage or current to the meter that
exceedsthe specified maximum:

SAFETY INFORMATION
The following safety information must be observed to ensure maximum personal safety during
the operation of this meter:
• Do not use the meter if the meter or test leads look damaged, or if you suspect that the meter
is not operating properly.
• Never ground yourself when taking electrical measurements. Do not touch exposed metal
pipes, outlets, xtures, etc., which might be at ground potential. Keep your body isolated from
ground by using dry clothing, rubber shoes, rubber mats, or any approved insulating material.
• Turn off power to the circuit under test before cutting, unsoldering, or breaking the circuit.
Small amounts of current can be dangerous.
• Use caution when working above 60V DC or 30V AC rms. Such voltages pose a shock
hazard.
• When using the probes, keep your ngers behind the nger guards on the probes.
• Measuring voltage which exceeds the limits of the multimeter may damage the meter and
expose the operator to a shock hazard. Always recognize the meter voltage limits as stated
on the front of the meter.
• Never apply voltage or current to the meter that exceeds the specied maximum:

SAFETY SYMBOLS
This symbol adjacent to another symbol, terminal or
operating device indicates that the operator must
refer to an explanation in the Operating Instructions
to avoid personal injury or damage to the meter.
This
WARNING symbol indicates a potentially
hazardous situation, which if not avoided, could
result in death or serious injury.
This
CAUTION symbol indicates a potentially
hazardous situation, which if not avoided, may
result in damage to the product.
This symbol advises the user that the terminal(s) so
marked must not be connected to a circuit point at
which the voltage with respect to earth ground
exceeds (in this case) 1000 VAC or VDC.
This symbol adjacent to one or more terminals
identifies them as being associated with ranges
that may, in normal use, be subjected to
particularly hazardous voltages. For maximum
safety, the meter and its test leads should not be
handled when these terminals are energized.

WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very

If “1” appears in the display during a measurement, the value exceeds the range you have
selected. Change to a higher range.
WARNING: On some low AC and DC voltage ranges, with the test leads 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 stabilise and give a proper measurement when
connected to a circuit.
DATA HOLD BUTTON
The Data Hold function allows the Multimeter to “freeze” a measurement for later reference.
1. Press the DATA HOLD button to “freeze” the reading on the Multimeter. The indicators
“HOLD” will 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 turn off automatically within around 3 seconds.
°C/°F BUTTON
The ºC/ºF button is used to select °C or °F function when making temperature measurements.
Set the rotary switch at TEMP position and “°C” is displayed. Push the °C/°F SWITCH, “°F” will be
displayed.
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 Multimeter.
1. Set the function switch to the V DC position (“mV” will appear in 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.

7
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 Multimeter.
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.).
DC CURRENT MEASUREMENTS
CAUTION: Do not make current measurements on the 20A scale for longer than 30 Seconds.
Exceeding 30 seconds may cause damage to the Multimeter and/or the test leads.
1. Insert the black test lead banana plug into the negative (COM) jack.
