OPERATING INSTRUCTIONS
WARNING: Risk of electrocution. High-voltage circuits, both AC and DC,
are very dangerous and should be measured with great care.
1. ALWAYS turn the function switch to the OFF position when the meter is
not in use.
2. If “OL” appears in the display during a measurement, the value exceeds
the range you have selected. Change to a higher range.
NOTE: 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
stabilize and give a proper measurement when connected to a circuit.
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.
1. Set the function switch to the highest V DC
position.
2. Insert the black test lead banana plug into the
negative (COM) jack.
Insert the red test lead banana plug into the
positive (V) jack.
3. Touch the black test probe tip to the negative side
of the circuit.
Touch the red test probe tip to the positive side of
the circuit.
4. Read the voltage in the display. Reset the
function switch to successively lower V DC
positions to obtain a higher resolution reading.
The display will indicate the proper decimal point and value. If the
polarity is reversed, the display will show (-) minus before the value.

11
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 highest V AC position.
2. Insert the black test lead banana plug into the
negative (COM) jack.
Insert red test lead banana plug into the positive (V)
jack.
3. Touch the black test probe tip to the negative side of
the circuit.
Touch the red test probe tip to the positive side of
the circuit.
4. Read the voltage in the display. Reset the function
switch to successively lower V AC positions to obtain
a higher resolution reading. The display will indicate
the proper decimal point and value.

12
DC CURRENT MEASUREMENTS
CAUTION: Do not make current measurements on the 10A scale for
longer than 30 seconds. Exceeding 30 seconds may cause damage to
the meter and/or the test leads.
1. Insert the black test lead banana plug into the negative
(COM) jack.
2. For current measurements up to 200mA DC, set the
function switch to the highest DC mA position and
insert the red test lead banana plug into the (mA) jack.
3. For current measurements up to 10A DC, set the
function switch to the 10A range and insert the red test
lead banana plug into the (10A) jack.
4. Remove power from the circuit under test, then open
up the circuit at the point where you wish to measure
current.
5. Touch the black test probe tip to the negative side of the circuit.
Touch the red test probe tip to the positive side of the circuit.
6. Apply power to the circuit.
7. Read the current in the display. For mA DC measurements, reset the
function switch to successively lower mA DC positions to obtain a
higher resolution reading. The display will indicate the proper decimal
point and value.

13
RESISTANCE MEASUREMENTS
WARNING: To avoid electric shock, disconnect power to the unit under
test and discharge all capacitors before taking any resistance
measurements. Remove the batteries and unplug the line cords.
1. Set the function switch to the highest $# position.
2. Insert the black test lead banana plug into the
negative (COM) jack
Insert the red test lead banana plug into the
positive $ jack.
3. Touch the test probe tips across the circuit or
part under test. It is best to disconnect one side
of the part under test so the rest of the circuit will
not interfere with the resistance reading.
4. Read the resistance in the display and then set
the function switch to the lowest $ position that is
greater than the actual or any anticipated resistance. The display will
indicate the proper decimal point and value.
CONTINUITY CHECK
WARNING: To avoid electric shock, never measure continuity on
circuits or wires that have voltage on them.
1. Set the function switch to the position.
2. Insert the black lead banana plug into the
negative (COM) jack
Insert the red test lead banana plug into the
positive ($) jack.
3. Touch the test probe tips to the circuit or wire
you wish to check.
4. If the resistance is less than approximately 30$,
the audible signal will sound. If the circuit is
open, the display will indicate “1”.
