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.

10
for more than one second
second to manually adjust the backlight. Meter default is automatic
control of backlight based upon an optical sensor. The long presses
will scroll between high backlight, low backlight, and back to
automatic control. In automatic backlight mode, the "A" and
icons will be displayed. For manual backlight mode, the "M" and
icons will be displayed
"RANGE" BUTTON

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.

Resistance, Temperature, Capacitance and LoZ.
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

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.

AC/DC VOLTAGE (LESS THAN 1000V)
1. Insert RED test lead into VΩ jack
5
, and BLACK test lead into
COM jack
4
, and rotate function selector switch
2
to the V
setting.
NOTE: The meter defaults to AC measurement. To measure DC, press
the "SEL" button
11
to toggle between AC and DC modes. The AC or
DC icon on the LCD indicates which mode is selected.
2. Apply test leads to the circuit to be tested to measure voltage.
The meter will auto-range to display the measurement in the
most appropriate range.
NOTE: The hazardous voltage indicator will appear for voltages >30V.
NOTE: If "–" appears on the LCD, the test leads are being applied to
the circuit in reverse. Swap the position of the leads to correct this.
NOTE: When in a voltage setting and the test leads are open,
readings of order mV may appear on the display. This is noise and
is normal. By touching the test leads together to close the circuit
the meter will measure zero volts.
AC/DC LO Z VOLTAGE (LESS THAN 600V)
Voltage measurements in Low Impedance (Lo Z) setting can be used
to identify ghost or stray voltages.
• Follow same procedure for measuring AC/DC Voltage (see above)
with Function Selector switch
2
in the Lo Z setting.
DO NOT attempt to measure voltages greater than 600V in
Lo Z setting.
