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 either of the OFF settings. By default, the meter will automatically power OFF after 30 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 settings) to power ON the meter. To deactivate the power OFF functionality press and hold the "RANGE" 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.

DATA HOLD
Press either of the Data Hold / Backlight buttons or to hold the measurement on the display. Press again to release the display to return to live measuring.

BACKLIGHT
Press and hold either of the Data Hold / Backlight buttons or 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 . 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 ( 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
When the "MAX/MIN" button is pressed, the meter keeps track of the Maximum and Minimum values and the difference between 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 the Minimum value (MIN).
2. Press "MAX/MIN" button for more than one second to return to normal measuring mode.

NON-CONTACT VOLTAGE TESTING
Press the NCV button to test for AC voltage using the integrated non-contact voltage meter. Approach the conductor under test leading with the sensing antenna . The meter delivers visual warning signals when AC voltage is detected.

TEST LEAD HOLDER
When working with test leads, one test probe may be mounted in the test lead holder to facilitate natural two-handed operation with the clamp in one hand and a single test probe in the other.

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.

AC CURRENT (LESS THAN 600A)
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 switchto the AC current A setting.
2. Place clamp around wire. The current measurement will be shown in the display. The meter will auto-range to display the measurement in the most appropriate range.

Disconnect test leads when measuring with the clamp.

AC VOLTAGE (LESS THAN 1000V)

1. Insert RED test lead into VΩ jack , and BLACK test lead into COM jack , and rotate function selector switch to the AC voltage V setting.
   
2. 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.

DC VOLTAGE (LESS THAN 1000V)

1. Insert RED test lead into VΩ jack , and BLACK test lead into COM jack , and rotate function selector switch to the DC voltage V setting.
   
2. 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: 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.

CONTINUITY

1. Insert RED test lead into VΩ jack , and BLACK test lead into COM jack , and rotate function selector switch to the Continuity setting.
2. Remove power from circuit.
3. Test for continuity by connecting conductor or circuit with test leads. If resistance is measured less than 50Ω, 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.

RESISTANCE MEASUREMENTS

1. Insert RED test lead into VΩ jack , and BLACK test lead into COM jack , and rotate function selector switch to the Resistance setting.
2. Remove power from circuit.
3. Measure resistance by connecting test leads to circuit. The meter will auto-range to display the measurement in the most appropriate range.
   

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 Diode-Test setting.
2. Touch test leads to diode. A reading of 200-800mV 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.
   

MAINTENANCE

BATTERY REPLACEMENT
When indicator is displayed on LCD, batteries must be replaced.

1. Remove screw from battery door.
2. Replace 2 x AAA batteries (note proper polarity).
3. Replace battery door and fasten securely with screw.

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.

CLEANING

Be sure meter is turned off and wipe with a clean, dry lint-free cloth. Do not use abrasive cleaners or solvents.

STORAGE

Remove the batteries when meter is not in use for a prolonged period of time. Do not expose to high temperatures or humidity. After a period of storage in extreme conditions exceeding the limits mentioned in the General Specifications section, allow the meter to return to normal operating conditions before using.

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 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.
• 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.
