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.

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

• 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.

• Usage of this meter in any way other than that specified by the

manufacturer can impair safe operation, resulting in severe injury or death.

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 ON the

meter. To deactivate the power OFF functionality, press the Display

Brightness button

for more than one second while the meter is

powered on.

"SELECT" BUTTON (FOR SECONDARY FUNCTIONS)

The "SELECT" button

activates the secondary function for each

application accessible by the function selector switch

. 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.

DISPLAY BRIGHTNESS

The OLED display can be operated at three different brightness levels

(low, medium, high). Press the Display Brightness button

to cycle

through and select the desired brightness.

DUAL DISPLAY LINES

The display has a primary and secondary display line. The primary

measurement is always displayed on the primary display line. When

measuring AC voltage, the measurement is displayed on the primary

display line, and the frequency is displayed on the secondary display

line.

NOTE:

When measuring at the lower extremes of a voltage

range (less than 10% of the range maximum, or below 100V for the

600V range), it may not be possible to measure frequency, which

may result in dashes on the display. In MAX/MIN mode, the primary

and secondary display lines are utilized as detailed in the MAX/MIN

section.

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 display). 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).

MAX/MIN

When the "MAX/MIN" button

is pressed, the meter keeps track of

the Maximum, Minimum and Average values as the meter continues

to take samples.

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

to display the

Max value on the primary display line. MAXMIN and Max will

be shown on the display. Pressing "MAX/MIN"

will toggle

between the Maximum (Max), the Minimum (Min), and the

Average (Avg) values. The active measurement continually

updates on the secondary display line in this mode. If a new

maximum or minimum occurs, the display updates with that

new value. The average value continues to update as the meter

continues to take samples.

2. Press "MAX/MIN" button

for more than one second 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 / 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

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 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

to the 40 A setting for improved resolution. If the

measurement is less than 4A, rotate the Function Selector switch

to the 4 A setting for improved resolution.

Disconnect test leads when measuring with the clamp.
