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

from

the OFF setting to any measurement setting. To power OFF the meter,

rotate the Function Selector switch

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

switch to OFF, then power ON the meter.

To deactivate

the power OFF functionality press and hold the "SELECT" button

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

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

In the presence of AC

voltage, the red NCV light

will flash, audible signals (beeps) will

sound.

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

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

1. Press the "RANGE" button

to manually select measurement

range ( is deactivated on the LCD). Repeatedly press the

"RANGE" button

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

for more than two seconds ( is reactivated).

MAX/MIN

When the "MAX/MIN" button

is pressed, the meter keeps track of

the Maximum and Minimum values.

www. .com information@itm.com1.800.561.8187

1. When measuring, press "MAX/MIN" button

to toggle between

the Maximum value (MAX), the Minimum value (MIN). If a new

maximum or minimum occurs, the display updates with that new

value.

2. Press "MAX/MIN" button

for more than two seconds to return

to normal measuring mode.

DATA HOLD

Press HOLD

to hold the measurement on the display. Press

HOLD

again to release the display to return to live measuring.

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 600A)

AC Current is measured by pressing the clamp trigger

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

fully released, and that the wire

passes perpendicularly through the center of the clamp in line with

the arrow markings

To measure current:

1. Rotate the Function Selector switch

to the A~ setting.

2. Place clamp around wire. The current

measurement will be shown in the display.

Disconnect test leads when

measuring with the clamp.

ENGLISH

Red leadBlack lead

NOTE: Current

measurement can be

made by clamping

around single

conductors, but not

cables containing

both live and neutral

wires. In this case a

line splitter is required,

Klein Cat. No. 69409 is

recommended.

AC/DC VOLTAGE (LESS THAN 600V)

1. Insert RED test lead into VΩµA jack

, and BLACK test lead

into COM jack

, and rotate function selector switch

to the

Vsetting for AC or DC measurements. The meter defaults to

AC measurement. To measure DC, press the "SELECT" button

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.
