OPERATION
NOTE: Before continuity test, disconnect all power to the
circuit to be tested, and discharge all capacitors fully.
Connect the black test lead to the COM jack and the

built-in buzzer will sound.
DIODE TEST
(See Figure 11.)
NOTE: Before diode test, disconnect all power to the
circuit to be tested, and discharge all capacitors fully.
Q Connect the black test lead to the COM jack and the
red test lead to the
NOTE: The polarity of the red lead is positive ( + ).
Set the mode selection dial to

Connect the red test lead to the anode of the diode
Q
to be tested, and the black test lead to the cathode of
the diode .
Q Read the approximate forward voltage drop of the
diode on the display.
If the connection is reversed, OL will be shown on the
Q
display.
MEASURING CAPACITANCE
NOTE: Before measurement, make sure that the
capacitor to be measured has been discharged fully.
Connect the black test lead to the COM jack and the

measured.
Q Wait until the reading is stable, then take the reading.
For high capacitance measurements, it may take
about 30 seconds for reading to be stable.
AUTOMATIC POWER OFF
Q The display will go blank and the meter will go into
Sleep mode if you do not turn the mode selection dial
or press any button for about 15 minutes. Pressing
any button arouses the meter from Sleep.
To disable the automatic power-off feature, press and hold down
any button while rotating the mode selection dial from OFF position.

MAINTENANCE
WARNING
When servicing, use only identical RYOBI
replacement parts. Use of any other parts may
create a hazard or cause product damage.
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
, the
Use clean cloths to remove dirt, dust, oil, grease, etc.
WARNING
Do not at any time let brake fluids, gasoline,
petroleumbased products, penetrating oils, etc.,
come in contact with plastic parts. Chemicals can
damage, weaken or destroy plastic which may
result in serious personal injury.
Do not abuse battery products. Abusive practices can
damage tool as well as workpiece.
WARNING
Do not attempt to modify this tool or create
accessories not recommended for use with this
tool. Any such alteration or modification is misuse
and could result in a hazardous condition leading
to possible serious personal injury.
CLEANING THE TERMINALS
Dirt or moisture in the terminals can affect readings.
To clean the terminals:
Set the mode selection dial to OFF position and
Q
remove the test leads from the meter.
Remove battery cover and the battery pack. Reinstall
Q
the battery cover.
Q Shake out any dirt which may exist in the terminals.
Q Soak a new swab with alcohol.
Q Work the swab around in each terminal.
REPLACING THE FUSE
To prevent damage or injury, install only replacement
fuses with the specified amperage, voltage, and interrupt
ratings.
This meter uses two fuses:
Fuse 1:
F 400mA 690V, Fast, Min. Interrupt Rating 10000A, ø10
x 38mm
Fuse 2:
F 10A, 600V/690V, Fast, Min. Interrupt Rating 10000A,
ø10 x 38 mm
