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.

• Do not hold meter above hand & finger guard during use.

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 aprox. 30 minutes of

inactivity. To deactivate the auto power OFF functionality, press and

hold the "SEL/DC ZERO" 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 (SELECT) / DC ZERO BUTTON (FOR SECONDARY FUNCTIONS)

The SEL/DC ZERO button

activates the secondary function for

each application accessible by the function selector switch

• In Current

and Low Impedance modes, it toggles between

AC and DC measurements.

• In Frequency/Duty Cycle

setting, it toggles between these

measurements

• In Continuity/Resistance/Diode-Test

setting, it toggles

through these measurements in order

• In DC current setting, pressing and holding for more than one

second initiates the DC ZERO function. Subsequent DC current

measurements automatically subtract the measurement that was

present as an offset correction.

The default function for each application is printed on the meter in

white, the secondary functions in orange. An icon on the LCD display

will indicate which function is active.

DATA HOLD

Press the Data Hold / Backlight button

to hold the measurement

on the display. Press again to release the display to return to live

measuring.

BACKLIGHT

Press and hold the Data Hold / Backlight button

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

AUTO

. 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 (AUTO 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 one second (AUTO is reactivated).

ENGLISH

FUNCTION BUTTONS

MAX/MIN

When the "MAX/MIN" button

is pressed, the meter keeps track of

the Maximum and Minimum values as the meter continues to take

samples.

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

to toggle between

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

Maximum or Minimum, the display will update with the new value.

2. Press "MAX/MIN" button

for more than one second to return to

normal measuring mode.

INRUSH CURRENT

Rotate the Function Selector switch

to the Current

setting

and

press INRUSH

prior to an inrush event to test for inrush

current. While the meter monitors current waiting for the inrush

event, "----" will be visible on the display.

NON-CONTACT VOLTAGE TESTING

Press and hold the "NCV" button

to test for AC voltage using the

integrated non-contact voltage tester. Approach the conductor under

test leading with the sensing antenna

. The meter delivers visual

warning signals via the LED indicator

and audible signals (beeps)

when AC voltage is detected. Release the "NCV" button to exit NCV

testing mode.

NOTE: It is not recommended to perform continuity and NCV testing

simultaneously, as both tests utilize the same audible signal, making

it difficult to resolve which test is responsible for the audible alarm.

NOTE: Only voltages of 90V AC or greater will be detected.

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.

INCORRECT

CORRECT

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/DC CURRENT (LESS THAN 2000A)

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

Current

setting

2. The meter defaults to AC measurement.

To measure DC, press the

"SEL/DC ZERO" 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.

3. Place the clamp

around the wire.

When measuring DC current, align the

polarity markings

on the clamp with

the polarity of the wire to avoid negative

readings. The current measurement will be shown in the display.

The meter will auto-range to display the measurement in the

most appropriate range.

To measure inrush current:

1. Rotate the Function Selector switch

to the Current

setting.

Place the clamp

around the wire and press "INRUSH"

. The

Display

will show "----". Initiate the Inrush event and the inrush

current will be captured and presented in the display. A second press of

"INRUSH"

will reset the Inrush measurement, "----" will be presented

on the display and the meter will wait for the next Inrush event.

2. P

ress and hold

"INRUSH"

for more than one second to return to

normal measuring mode.

Disconnect test leads when measuring with the clamp.

NOTE: If non-zero values are displayed prior to measuring in DC

current mode, an offset correction may be required to improve

accuracy. With meter in DC current mode, press and hold the

"SEL/DC ZERO" button

for more than one second to initiate the

DC current ZERO function. Subsequent DC current measurements

automatically subtract the measurement that was initially present as

an offset correction.
