Product Information

The Klein Tools CL360 is a digital open jaw fork meter that is capable of measuring AC/DC voltage, continuity, resistance, and AC current via the fork. It uses true root mean square (TRMS) measurement technology and has an integrated non-contact voltage (NCV) tester to detect the presence of voltage. The meter has a CAT III 600V and CAT II 1000V rating and comes with test leads and shields for safe usage in different measurement locations.

Product Usage Instructions

Connecting Test Leads

Firmly press the test leads into the input jack completely to ensure proper connection.
Do not test if leads are improperly seated as it may cause intermittent display readings.

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 200A)

Rotate the Function Selector switch to the AC current A setting.
Place the open jaw fork around the wire ensuring that the wire passes perpendicularly through the center of the open jaw fork in line with the arrow markings.
The current measurement will be shown in the display.
Disconnect test leads when measuring with the open-jaw fork.

AC Voltage (Less Than 600V)

Insert the RED test lead into V jack and BLACK test lead into COM jack.
Rotate function selector switch to the AC voltage V setting.
Note AC on the display.
Apply test leads to the circuit to be tested to measure AC voltage.
The measurement will be presented in the display.
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.

DC Voltage (Less Than 1000V)

Insert the RED test lead into V jack and BLACK test lead into COM jack.
Rotate function selector switch to the DC voltage V setting. Note DC on the display.
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.

Continuity

Insert the RED test lead into V jack and BLACK test lead into COM jack.
Rotate function selector switch to the Continuity setting. The Continuity icon will appear on the display.
Remove power from circuit.
Test for continuity by connecting conductor or circuit with test leads.
If resistance is measured less than 10, an audible signal will sound and display will show a resistance value indicating continuity.
If circuit is open display will show OL.

WARNINGS

To ensure the 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 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 the risk of electric shock, disconnect leads from any voltage source before removing the battery door.
To avoid the risk of electric shock, do not operate the meter while the battery door is removed.

WARNINGS – NCV FUNCTION

When NCV Function is initiated, a blinking or steady red glow and an audible beep indicate voltage present. If no indication, the voltage could still be present.
Before and after each use of the NCVT, verify operation by testing a known working circuit that is within the rating of this unit.
Never assume neutral or ground wires are de-energized. Neutrals in multi-wire branch circuits may be energized when disconnected and must be retested before handling.
The NCV tester WILL NOT detect voltage if :
- The wire is shielded.
- The operator is not grounded or is otherwise isolated from effective earth ground.
- The voltage is DC.
The NCV tester MAY NOT detect voltage if:
- The user is not holding the tester.
- The user is insulated from the tester with a glove or other materials.
- The wire is partially buried or in a grounded metal conduit.
- The tester is at a distance from the voltage source.
- The field created by the voltage source is blocked, dampened, or otherwise interfered with.
- The frequency of the voltage is not a perfect sine wave between 50 and 500Hz.
- The tester is outside of operation conditions (listed in the Specifications section).
The operation may be affected by differences in socket design and insulation thickness and type; the tester may not be compatible with some types of standard or tamper-resistant (TR) electrical outlets.
Do not apply to uninsulated hazardous live conductors.
Detection above 50V is specified under “normal” conditions as specified below. The tester may detect at a different threshold at different conditions, or may not detect at all unless:
- The tip of the tester is within 0.25″ of an AC voltage source radiating unimpeded.
- The user is holding the body of the tester with his or her bare hand.
- The user is standing on or connected to earth’s ground.
- The air humidity is nominal (50% relative humidity).
- The tester is held still. 4
