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.

• Probe assemblies to be used for MAINS measurements should

meet EN61010-031 standard, rated CATIII 600V, 10A or better.

• 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.

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.

FUNCTION BUTTONS

ON/OFF

Power-ON: Rotate the Function Selector switch

from the OFF

setting to any measurement setting.

Power-OFF: Rotate the Function Selector switch

to the OFF setting.

Auto Power-OFF: By default, the meter will automatically Power-

OFF after 15 minutes of inactivity. Reactivate meter by pressing any

button. To deactivate the automatic Power OFF feature, power the

meter ON with the "HOLD" button

depressed. When automatic

Power OFF is deactivated, the Auto Power-OFF symbol will not

be visible in the display.

HOLD (DATA HOLD)

Press the "HOLD" button

to hold the measurement on the display.

Press again to release the display and return to live measuring.

BACKLIGHT

Press and hold the Backlight button

for more than one second

to turn the backlight on or off. Backlight automatically turns off

after approximately 3 minutes.

LEAD ALERT LEDs

When the Function Selector switch

is rotated to a measurement

setting, the Lead Alert LEDs

will illuminate green to ensure that

the test leads are inserted into the appropriate jacks. The lights will

automatically turn off after 2 minutes. To disable the Lead Alert LEDs

, power the meter ON while holding the Backlight button

NOTE: Lead Alert function will reactivate by default when the meter

powers OFF or when the Function Selector switch is rotated.

OPERATING INSTRUCTIONS

TESTING IN CAT III / CAT IV MEASUREMENT LOCATIONS

Ensure the test lead shield is pressed firmly in place. Failure to use

the CAT III / CAT IV 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.

AC VOLTAGE (LESS THAN 600V)

1. Insert RED test lead into VΩ jack

, and BLACK test lead into

COM jack

, and rotate Function Selector Switch

to the

highest V AC ( ) setting (600V).

2. Measure voltage and rotate the Function Selector Switch

to successively lower V AC ( ) settings to obtain higher

resolution measurements.

NOTE: The hazardous voltage indicator will appear for voltages >30V.

NOTE: Do not attempt to measure more than 600V or 200mA.

Red leadBlack lead

DC CURRENT 200mA to 10A

1. For DC currents more than 200mA and less than 10A, insert

RED test lead into 10A jack

, and BLACK test lead into COM

jack

, and rotate Function Selector Switch

to the

10A DC setting.

DC VOLTAGE (LESS THAN 600V)

1. Insert RED test lead into VΩ jack

, and BLACK test lead into

COM jack

, and rotate Function Selector Switch

to the

highest V DC ( ) setting (600V).

2. Measure voltage and rotate the Function Selector Switch

to successively lower V DC ( ) settings to obtain higher

resolution measurements.

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.

NOTE: The hazardous voltage indicator will appear for voltages >30V.

NOTE: Do not attempt to measure more than 600V or 200mA.

DC CURRENT LESS THAN 200mA

1. For mA DC currents less than 200mA, insert RED test lead into VΩ

jack

, and BLACK test lead into COM jack

, and rotate Function

Selector Switch

to the highest mA DC setting (200mA).

2. To measure current: Remove power from circuit, open circuit at

measurement point, connect meter in-series in the circuit using

the test leads, and apply power to circuit.

NOTE: If measuring mA, the Function Selector Switch

may

be rotated to successively lower mA DC settings to obtain higher

resolution measurements.

Red leadBlack lead

Do not attempt to measure more than 10A.

When measuring currents greater than 6A, a measurement

time of 30 seconds followed by 10 minutes of recovery time

is recommended.

RESISTANCE MEASUREMENTS

1. Insert RED test lead into VΩ jack

, and BLACK test lead into

COM jack

and rotate Function Selector Switch

to the

highest Ω setting (2MΩ).

2. Remove power from circuit.

3. Measure resistance by connecting test leads to circuit and

rotating the Function Selector Switch

to successively

lower Ω settings to obtain higher resolution measurements.

NOTE: When in a Resistance setting and the test leads are open

(not connected across a resistor), or when a failed resistor is under

test, the display will indicate O.L. This is normal.

DO NOT attempt to measure resistance on a live circuit.

DIODE TEST

1. Insert RED test lead into VΩ jack

and BLACK test lead into COM

jack

, and rotate Function Selector Switch

to the setting.

2. Touch test leads to diode. A reading of 200-700mV on display

indicates forward bias, OL indicates reverse bias. An open

device will show OL in both

polarities. A shorted device

will show approximately 0mV.

BATTERY TEST

1. Insert RED test lead into VΩ jack

and BLACK test lead into

COM jack

, and rotate Function Selector Switch

to the 1.5V

or 9V battery test setting.

2. Connect BLACK lead to negative, and RED lead to positive

terminal of battery.

3. Measure voltage on display,

batteries in good condition

should be within approx. 10%

of rated voltage.

OPERATING INSTRUCTIONS

CONTINUITY

1. Insert RED test lead into VΩ jack

and BLACK test lead into COM

jack

, and rotate Function Selector Switch

to the setting.

2. Remove power from circuit.

3. Test for continuity by connecting conductor or circuit with test

leads. If resistance is measured less than 100Ω, an audible

signal will sound and display will show a resistance value

indicating continuity. If circuit is

open, display will show "OL".

DO NOT attempt to measure continuity on a live circuit.
