WARNINGS
To ensure safe operation and service of the meter, follow these
instructions. Failure to observe these warnings can result in
severe injury or death.
• Before each use verify meter operation by measuring a known
voltage or current.
• Never use the meter on a circuit with voltages that exceed the
category based rating of this meter.
• Do not use the meter during electrical storms or in wet weather.
• Do not use the meter or test leads if they appear to be damaged.
• Use only with CAT IV rated test leads.
• Ensure meter leads are fully seated, and keep fingers away
from the metal probe contacts when making measurements.
• Do not open the meter to replace batteries while the probes
are connected.
• Use caution when working with voltages above 25V AC RMS
or 60V DC. Such voltages pose a shock hazard.
• To avoid false readings that can lead to electrical shock,
replace batteries when a low battery indicator appears.
• Do not attempt to measure resistance or continuity on a live
circuit.
• Always adhere to local and national safety codes. Use personal
protective equipment to prevent shock and arc blast injury
where hazardous live conductors are exposed.
• Meter is IP42 dust & water resistant. Following any contact
with water, thoroughly dry meter and test lead jacks prior to
subsequent use.

FUNCTION BUTTONS
ON/OFF
To Power ON the meter rotate the Function Selector switch
2
from
the OFF setting to any measurement setting. To Power OFF the meter
rotate the Function Selector switch
2
to the OFF setting. By default
the meter will automatically Power OFF after 30 minutes of inactivity.
Reactivate meter by pressing any button. To deactivate the automatic
Power OFF feature, power the meter ON with the SEL button
11
depressed. When automatic Power OFF is deactivated, the
symbol will not be visible in the display.
When the Function Selector switch is rotated to a measurement
setting, "LEAD" flashes on the display as a reminder to check that test
leads are inserted into the appropriate jacks.
"SEL" (SELECT) BUTTON (FOR SECONDARY FUNCTIONS)
The "SEL" button
11
activates the secondary functions for each
setting accessible by the Function Selector switch
2
. For Current,
Voltage and Low Z, it toggles between AC and DC. For the other
functions, it switches between °F and °C, between Hz and %
Duty-cycle, and between Continuity, Resistance, and Diode-test.
The default function for each application is printed on the meter in
white; the secondary functions are printed on the meter in orange.
"HOLD" (DATA HOLD / BACKLIGHT) BUTTON
Press HOLD
10
to hold the measurement on the display. Press
again to release the display to return to live measuring.
Press and hold the "HOLD" button
10
for more than one second to
turn on or off the backlight. The backlight will automatically Power
OFF following three minutes of inactivity to conserve battery life.
"RANGE" BUTTON
The meter defaults to auto-ranging measurement mode . This
automatically determines the most appropriate measurement range
for the testing that is being conducted. To manually force the meter
to measure in a different range, use the "RANGE" button
7
.
1. Press the "RANGE" button
7
to manually select measurement
range ( is deactivated on the LCD). Repeatedly press
the "RANGE" button
7
to cycle through the available ranges,
stopping once the desired range is reached.
2. To return to auto-ranging mode, press and hold the "RANGE"
button
7
for more than one second ( is reactivated).

FUNCTION BUTTONS
"REL" (RELATIVE) BUTTON
Relative measurements are available for Voltage, Current,
Resistance, Temperature and Capacitance.
1. Perform first measurement.
2. With test leads connected, press REL
8
to set frame of reference.
3. Perform second measurement. The value displayed is the
difference between first and second measurements.
"MAX/MIN" BUTTON
When the "MAX/MIN" button
9
is pressed, the meter keeps track
of the minimum and maximum value of the measurement as the
meter continues to take samples.
1. When measuring, press MAX/MIN
9
and the meter displays the
maximum value. If a new maximum occurs, the display updates
with that new value. Pressing again reveals the minimum value.
If a new minimum occurs, the display updates with the new
value.
2. Press MAX/MIN
9
and hold for more than one second to return
to normal measuring mode.

OPERATING INSTRUCTIONS
CONNECTING TEST LEADS
Do not test if leads are improperly seated. Results could cause
intermittent display readings. To ensure proper connection, firmly
press leads into the input jack completely.
TESTING IN CAT III / CAT IV MEASUREMENT LOCATIONS
Ensure the test lead shield is pressed firmly in place. Failure to use
the CAT III / CAT IV shield increases arc-flash risk.
TESTING IN CAT II MEASUREMENT LOCATIONS
CAT III / CAT IV shields may be removed for CAT II locations. This
will allow testing on recessed conductors such as standard wall
outlets. Take care not to lose the shields.
