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 III or CAT IV rated test leads.
• Ensure meter leads are fully seated, and keep fingers away from the
metal probe contacts when making measurements.
• 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.
• To avoid risk of electric shock, disconnect leads from any voltage source
before removing battery door.
• To avoid risk of electric shock, do not operate meter while battery door is removed.

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 10 minutes of inactivity.
If the meter automatically powers-OFF while in a measurement
setting, press any button to power the meter ON, or rotate Function
Selector
2
switch to OFF, then power ON the meter. To deactivate
the power OFF functionality press and hold the "SELECT" button
12
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.
SEL / NCV BUTTON (FOR NCV TESTING)
Press and hold the SEL/NCV button
12
to enter Non-contact Voltage
Testing (NCV) mode to test for presence of AC voltage. The NCV
icon and "EF" will be present on the display. Approach the conductor
under test leading with the sensing antenna
14
. In the presence of AC
voltage, the red NCV light
13
will flash, audible signals (beeps) will
sound, and dashes will appear on the display.
As the NCV sensing
antenna
14
approaches the voltage source, more dashes will be
presented on the display and the frequency of the audible sound will
increase. Release the SEL/NCV button to exit NCV testing mode.
NOTE: Only voltages of 40V AC or greater will be detected.
BACKLIGHT
Press Backlight button symbol
6
to turn ON or OFF the backlight.
The backlight does not automatically power OFF.
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 two seconds ( is reactivated).

8
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), the Minimum value (MIN), and the
difference between Maximum and Minimum (MAX-MIN) values.
If a new maximum or minimum occurs the display updates with
that new value.
2. Press "MAX/MIN" button
8
for more than two seconds to return
to normal measuring mode.
DATA HOLD
Press HOLD
9
to hold the measurement on the display. Press

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 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.

OPERATING INSTRUCTIONS
AC CURRENT (LESS THAN 400A)
AC Current is measured by pressing the clamp trigger
10
to open
the clamp and placing it around a current-carrying wire. When
measuring, care should be taken to ensure that the clamp is
completely closed with trigger
10
fully released, and that the wire
passes perpendicularly through the center of the clamp in line with
the arrow markings
11
.
To measure current:
1. Rotate the Function Selector switch
2
to the 40/400 A setting.
2. Place clamp around wire. The current measurement will be shown
in the display.
NOTE: If the measurement is less than 40A, rotate the Function
Selector switch
2
to the 4A setting for improved resolution. If the
measurement is less than 4A, the meter will auto-range to the 4A
range.
Disconnect test leads when measuring with the clamp.

The meter will auto-range to display the measurement in the most
appropriate range.
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.
