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.

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 either of the OFF
settings. By default, the meter will automatically power OFF after 30
minutes of inactivity. If the meter automatically powers OFF while in
a measurement setting, rotate Function Selector switch 2 to any
other setting (excluding the OFF settings) to power ON the meter. To
deactivate the power OFF functionality press and hold the "RANGE"
button 7 before powering ON from the OFF setting. When auto
power OFF is deactivated, the Auto Power Off icon will not be
visible in the display.

DATA HOLD

Press either of the Data Hold / Backlight buttons 6 or 9 to hold
the measurement on the display. Press again to release the display to
return to live measuring.

BACKLIGHT

Press and hold either of the Data Hold / Backlight buttons 6 or 9
for more than one second to turn ON the backlight. The backlight will
automatically power OFF after 3 minutes of inactivity.

RANGE

The meter defaults to auto-ranging mode . This mode
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

MAX/MIN

When the "MAX/MIN" button 8 is pressed, the meter keeps track
of the Maximum and Minimum values and the difference between
the Maximum and Minimum values as the meter continues to take
samples.

1. When measuring, press "MAX/MIN" button 8 to toggle between
the Maximum value (MAX) and the Minimum value (MIN).

2. Press "MAX/MIN" button 8 for more than one second to return to
normal measuring mode.

NON-CONTACT VOLTAGE TESTING

Press the NCV button

to test for AC voltage using the integrated

12

non-contact voltage meter. Approach the conductor under test

14

leading with the sensing antenna

. The meter delivers visual

warning signals when AC voltage is detected.

TEST LEAD HOLDER

When working with test leads, one test probe may be mounted in the
test lead holder

to facilitate natural two-handed operation with the

13

clamp in one hand and a single test probe in the other.

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 CATIII / CATIV 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.
