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.

WARNINGS

• 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 test leads are fully seated into jacks, 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. The

Auto-Power Off icon

will be visible in the display. By default, the meter will automatically power OFF after 5 minutes of inactivity. If the meter automatically powers-OFF while in a measurement setting, rotate Function Selector

switch to any other setting (excluding the OFF setting) to power ON the meter. To deactivate Auto-Power OFF functionality press and hold the "SEL/NCV" 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 SECONDARY FUNCTIONS)

Pushing the SEL/NCV button 12 activates the secondary function for each application accessible by the function selector switch

. For voltage and current (excluding DC uA), 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.

SEL / NCV BUTTON (FOR NCV TESTING)

Press and hold the SEL/NCV button 12 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 meter delivers visual warning signals as dashes on the display and audible signals (beeps). As the NCV sensing antenna

approaches the voltage source more dashes will be presented on the display and the frequency of the audible sound will increase. Release the "NCV" button to exit NCV testing mode.

NOTE: Only voltages of 70V AC or greater will be detected.

BACKLIGHT BRIGHTNESS

Press and hold the HOLD/Brightness button

to toggle between high and low brightness for the backlight. By default, the meter will use the low brightness setting.

RANGE

The meter defaults to auto-ranging mode for voltage and resistance measurements. This mode automatically determines the most appropriate measurement range for the testing that is being conducted. The

icon will be visible in the display. To manually force the meter

to measure in a different range, use the "RANGE" button

1. Press the "RANGE" button 6 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 one second ( is reactivated).

MAX/MIN

The "MAX/MIN" function can be used when measuring with voltage, current, resistance, temperature, and DC μA functions. When the "MAX/MIN" button 7 is pressed, the meter keeps track of the Maximum and Minimum values, and the difference between the Maximum and Minimum values while continuing to take samples.

1. When measuring, press "MAX/MIN" button 7 to toggle between

the Maximum value (MAX), the Minimum value (MIN), and the difference between Maximum and Minimum (MAX-MIN) values. "

MAX

", "

MIN

", or "

MAX-MIN

" will appear on the display, indicating the value being shown. If a new maximum or minimum occurs the display updates with that new value.

2. Press "MAX/MIN" button 7 for more than one second to return to normal measuring mode.

RELATIVE MODE REL Measurement: Press REL/ZERO 8 to initiate measurement

relative to the current reading. The REL icon will be present on the display. Subsequent measurements are displayed relative to the original measurement. (Applies to AC/DC Voltage, AC Current, Capacitance, DC μA, and Temperature). Press REL/ZERO 8 again to exit relative mode.

DC ZERO Function: When measuring DC current with the clamp, press REL/ZERO to activate the DC current zero function. This will set the display to zero by subtracting the current value as an offset. The ZERO icon will be present on the display. Press REL/ZERO 8 again to exit DC current zero mode.

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/DC 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 400A setting.

2. Place clamp around wire. The current measurement will be shown in the display.

NOTE: The meter defaults to AC measurement. Press the SEL/NCV button to toggle between AC and DC modes. The AC or DC icon on the display indicates which mode is selected.

NOTE: If the measurement is less than 40A, rotate the Function Selector switch

to the 40A setting for improved resolution.

NOTE: If non-zero values are displayed prior to measuring in DC current mode, a DC zero offset correction is required. With meter in DC current mode, press the REL/ZERO button

to activate the DC

current ZERO function.

ZERO

icon will be present on the display. Subsequent DC current measurements automatically subtract the offset correction for improved accuracy. Press REL/ZERO button

to return to normal measuring mode.

Disconnect test leads when measuring with the clamp.

OPERATING INSTRUCTIONS

AC/DC VOLTAGE (LESS THAN 600V)

1. Insert RED test lead into VΩ jack

, and BLACK test lead into

, and rotate function selector switch 2 to the

setting for AC or DC measurements. The meter defaults to

AC measurement. To measure DC, press the SEL/NCV button

to toggle between AC and DC modes. The AC or DC icon on the LCD indicates which mode is selected.

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, this indicates negative polarity for DC voltage.

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: When voltages in excess of 25V AC or 60V DC are measured the hazardous voltage indicator

will be present on the display.
