WARNING: USE EXTREME CAUTION IN THE USE OF THIS DEVICE.
Improper use of this device can result in injury or death. Follow all
safeguards suggested in this manual. In addition to the normal safety
precautions used in working with electrical circuits. DO NOT service this
device if you are not qualified to do so.
Thismeterhasbeendesignedforsafeuse,butmustbeoperatedwith

2. USE EXTREME CAUTION when working with high voltages.
3. DO NOT measure voltage if the voltage on the "COM" input jack
exceeds 500V above earth ground.
4. NEVER connect the meter leads across a voltage source while the
function switch is in the current, resistance, or diode mode. Doing so
can damage the meter.
5. ALWAYS discharge filter capacitors in power supplies and disconnect
the power when making resistance or diode tests.
6. ALWAYS turn off the power and disconnect the test leads before
opening the doors to replace the fuse or batteries.
7. NEVER operate the meter unless the back cover and the battery and
fuse doors are in place and fastened securely.

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
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) 500 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.
This symbol indicates that a device is protected
throughout by double insulation or reinforced insulation.

I WARNING: To avoid electric shock, disconnect the test leads from any I
source of voltage before removing the battery door. I
1.

4.
Disconnect the test leads from the meter.
Remove the protective rubber holster (if installed)_._t _
Open the battery door by loosening the screw using a
Phillips head screwdriver.
Insert the battery into battery holder, observing the
correct polarity.
Put the battery door back in place. Secure with the
screw.
I WARNING: To avoid electric shock, do not operate the meter until the I
battery door is in place and fastened securely.
I
NOTE: If your meter does not work properly, check the fuses and batteries
to make sure that they are still good and that they are properly inserted.
JWARNING: Risk of electrocution. High-voltage circuits, both AC and DC, J
are very dangerous and should be measured with great care.
I
1. ALWAYS turn the function switch to the OFF position when the meter is
not in use.
2. If "1" 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
J AUTION: 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.
I

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.
I 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
Idamage 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.
