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.
• 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 the OFF setting. By default,
the meter will automatically power OFF after 15 minutes of inactivity.
If the meter automatically powers-OFF while in a measurement
setting, rotate Function Selector
2
switch to any other setting
(excluding the OFF setting) to 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.
"SELECT" BUTTON (FOR SECONDARY FUNCTIONS)
The "SELECT" button
12
activates the secondary function for each
application accessible by the function selector switch
2
. For voltage,
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, Capacitance and Diode-Test. The default
function for each application is printed on the meter in white; the
secondary function or functions for each setting is printed on the
meter in orange.
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 one second ( 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 one second 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 / 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.

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 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 40 A setting for improved resolution. If the
measurement is less than 4A, rotate the Function Selector switch
2
to the 4 A setting for improved resolution.
Disconnect test leads when measuring with the clamp.

AC/DC VOLTAGE (LESS THAN 600V)
1. Insert RED test lead into VΩ jack
5
, and BLACK test lead into
COM jack

to the
Vsetting for AC or DC measurements. The meter defaults to
AC measurement. To measure DC, press the "SELECT" button
12
to toggle between AC and DC modes. The AC or DC icon on
the LCD indicates which mode is selected. Note "AC" or "DC" on
the display.
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: 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.
