This meter has been designed for safe use, but must be operated with
caution. The rules listed below must be carefully followed for safe operation.
1. NEVER apply voltage or current to the meter that exceeds the
specified maximum:

V DC or V AC
mA DC/AC
A DC/AC
Frequency, Resistance, Capacitance,
Duty Cycle, Diode test, Continuity
Temperature
Input Limits

2. USEEXTREMECAUTIONwhen 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.

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.
I ARNING: 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. This meter has Auto OFF that automatically shuts the meter
OFF if 15 minutes elapse between uses.
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.
AUTORANGING / MANUALRANGING SELECTION
When the meter is first turned on, it automatically goes into AutoRanging.
This automatically selects the best range for the measurements being
made and is generally the best mode for most measurements. For
measurement situations requiring that a range be manually selected,
perform the following:
1. Press the RANGE button. The "AUTO" display indicator will turn off.
2. Press the RANGE button to step through the available ranges until you
select the range you want.
3. Press and hold the RANGE button for 2 seconds to exit the
ManualRanging mode and return to AutoRanging.
DATA HOLD
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 indicator "HOLD" will appear in the display.
2. Press the DATA HOLD button to return to normal operation.
NOTE: The DATA HOLD function works in the FREQUENCY mode only
when a signal is present.
10
RELATIVE
The relative measurement feature allows you to make measurements
relative to a stored reference value. A reference voltage, current, etc. can
be stored and measurements made in comparison to that value. The
displayed value is the difference between the reference value and the
measured value.
1. Perform any measurement as described in the operating instructions.
2. Press the RELATIVE button to store the reading in the display and the
"REL" indicator will appear on the display.
3. The display will now indicate the difference between the stored value
and the measured value.
4. Press the RELATIVE button to return to normal operation.
DC VOLTAGE MEASUREMENTS
I AUTION: Do not measure DC voltages if a motor on the circuit is I
being switched ON or OFF. Large voltage surges may occur that can
I
damage the meter.
1. Set the function switch to the V DC position CmV" 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.
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 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
I CAUTION: DO not make current measurements on the 10A scale for I
I
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 4000!_A DC, set the
function switch to the !_A position and insert the red test
lead banana plug into the (!_A)jack.
3. For current measurements up to 400mA DC, set the
function switch to the mA range and insert the red test lead
banana plug into the (mA) jack.
4. For current measurements up to 10A DC, set the function switch to the
A position and insert the red test lead banana plug into the 10A jack.
5. Press the AC/DC button until "DC" appears in the display.
