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.
- 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.
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)
- Insert RED test lead into VΩ jack 5, and BLACK test lead into COM jack 4, and rotate the function selector switch 2 to the highest V AC
setting (600V).
- Measure voltage and rotate the function selector switch to successively lower V AC
settings to obtain higher resolution measurements.
NOTE: Do not attempt to measure more than 600V or 200mA.
DC VOLTAGE (LESS THAN 600V)
- Insert RED test lead into VΩ jack 5, and BLACK test lead into COM jack 4, and rotate the function selector switch 2 to the highest V DC
setting (600V).
- 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: Do not attempt to measure more than 600V or 200mA.
DC CURRENT 200mA to 10A
- For DC currents more than 200mA and less than 10A, insert RED test lead into 10A jack 3, and BLACK test lead into COM jack 4, and rotate function selector switch 2 to the 10A DC setting.
- DC CURRENT LESS THAN 200mA
2. For mA DC currents less than 200mA, insert RED test lead into VΩ jack 5, and BLACK test lead into COM jack 4, and rotate function selector switch 2 to the highest mA DC setting (200mA). - To measure current: Remove power from the circuit, open the circuit at the measurement point, connect the meter in series using the test leads, and apply power to the circuit. The meter will autorange to display the measurement in the most appropriate range.
NOTE: If measuring mA, the function selector switch 2 may be rotated to lower mA DC settings to obtain higher resolution measurements successively.
RESISTANCE MEASUREMENTS
- Insert the RED test lead into VΩ jack 5, and the BLACK test lead into COM jack 4, and rotate the function selector switch 2 to the highest setting (2M).
- Remove power from the circuit.
- Measure resistance by connecting test leads to the circuit and rotating the function selector switch 2 to successively lower 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.
CONTINUITY
- Insert RED test lead into VΩ jack 5 and BLACK test lead into COM jack 4, and rotate the function selector switch 2 to the
setting.
- Remove power from the circuit.
- Test for continuity by connecting the conductor or circuit with test leads. If resistance is measured less than 100, an audible signal will sound and the display will show a resistance value indicating continuity. If the circuit is open, the display will show “OL”.
DIODE TEST
- Insert RED test lead into VΩ jack 5 and BLACK test lead into COM jack 4, and rotate function selector switch 2 to the setting.
- Touch test leads to the 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
- Insert RED test lead into VΩ jack 5 and BLACK test lead into COM jack 4, and rotate the function selector switch 2 to the 1.5V or 9V battery test setting.
- Connect the BLACK lead to the negative, and the RED lead to the positive terminal of the battery.
- Measure voltage on display, batteries in good condition should be within approx. 10% of rated voltage.
DATA HOLD
Press the Data Hold button 6 to hold the measurement on the display. Press again to release the display and return to live measuring.
MAINTENANCE
BATTERY REPLACEMENT
When the indicator is displayed on the LCD, the batteries must be replaced.
- Remove screw from battery door.
- Replace 2 x AAA batteries (note proper polarity).
- Replace battery door and fasten securely with screw.
FUSE REPLACEMENT
A fuse may blow if more than 200mA is applied to the VΩ jack 5, or more than 10A is applied to the 10A jack 3. To access fuses:
- Remove 6 screws from back of meter and remove back housing.
- Replace blown fuse(s) with:
VΩ (μA/mA) jack 5: 200mA/600V fast-blow (Klein Cat. No. 69031) 10A jack 3 : 10A/600V fast-blow (Klein Cat. No. 69032) - Replace back housing and fasten securely with screws.
CLEANING
Be sure the 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 the 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.
WARRANTY
