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.

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

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 A~ setting.

2. Place clamp around wire. The current

measurement will be shown in the display.

Disconnect test leads when

measuring with the clamp.

NOTE: Current

measurement can be

made by clamping

around single

conductors, but not

cables containing

both live and neutral

wires. In this case a

OPERATING INSTRUCTIONS

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: To access mV range for V AC , the 'RANGE' button

7

must

be used.

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.

INRUSH CURRENT

The Inrush feature captures starting current of a motor or transformer.

Starting current can assist in diagnosing a motor before it fails.

To measure inrush current:

1. Rotate the Function Selector switch

2

to the AC current A setting.

2. Place clamp

3

around wire. The current measurement will be

shown in the main display.

3. Press the InRush button

17

to enter the Inrush mode and manually

select 60A or 600A range

by pressing the RANGE button
