1. Introduction

This manual provides essential instructions for the safe and effective operation, maintenance, and troubleshooting of your Fluke 362 200A AC/DC Clamp Meter. Please read this manual thoroughly before using the device to ensure proper functionality and safety.

The Fluke 362 is a compact and versatile clamp meter designed for measuring AC and DC current up to 200A, AC and DC voltage up to 600V, resistance up to 3000 Ω, and continuity. Its ergonomic design and robust construction make it suitable for various electrical measurement tasks.

2. Safety Information

WARNING: To prevent possible electrical shock, fire, or personal injury, read all safety information before you use the product.

• Always adhere to local and national safety codes.
• Do not use the meter if it is damaged or operating abnormally.
• Ensure the function switch is in the correct position for the measurement being performed.
• Do not apply more than the rated voltage, as marked on the meter, between the terminals or between any terminal and earth ground.
• The Fluke 362 is rated for CAT III 600 V. This rating indicates suitability for measurements in distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, and socket outlets in the fixed installation, and industrial use equipment.
• Use caution when working with voltages above 30 V AC RMS, 42 V peak, or 60 V DC. These voltages pose a shock hazard.
• Remove test leads from the circuit before opening the battery cover.
• Replace batteries when the low battery indicator appears to ensure accurate readings.

• Large, clear display for easy viewing.
• Compact and lightweight design for one-hand operation.
• CAT III 600 V safety rating.

4. Setup

4.1 Battery Installation

The Fluke 362 is battery-powered. Although batteries are not included with all packages, they are required for operation. To install or replace batteries:

1. Ensure the meter is turned OFF and no test leads are connected.
2. Locate the battery compartment cover on the back of the meter.
3. Use a screwdriver to loosen the screw(s) securing the cover.
4. Remove the cover and insert the required batteries, observing correct polarity (+/-).
5. Replace the battery cover and tighten the screw(s).

4.2 Test Lead Connection

For voltage, resistance, and continuity measurements, connect the test leads to the input terminals:

• Insert the black test lead into the “COM” (common) terminal.
• Insert the red test lead into the “VΩ” (voltage/resistance) terminal.

5. Operating Instructions

5.1 Powering On/Off

Rotate the function dial from the “OFF” position to any desired measurement function to power on the meter. To power off, rotate the dial back to the “OFF” position.

5.2 Function Selection

Use the rotary function dial to select the desired measurement mode (e.g., A∼ for AC current, A— for DC current, V∼ for AC voltage, V— for DC voltage, Ω for resistance, or continuity).

5.3 AC/DC Current Measurement (Clamp)

To measure current using the clamp jaw:

1. Rotate the function dial to A∼ (AC current) or A— (DC current).
2. For DC current measurements, press the “ZERO” button to clear any offset before clamping.
3. Open the clamp jaw by pressing the trigger.
4. Enclose only one conductor within the jaw. Ensure the jaw is fully closed.
5. Read the current value on the display.

5.4 AC/DC Voltage Measurement

To measure voltage:

1. Connect the test leads as described in Section 4.2.
2. Rotate the function dial to V∼ (AC voltage) or V— (DC voltage).
3. Connect the test probes in parallel to the circuit or component you wish to measure.
4. Read the voltage value on the display.

5.5 Resistance Measurement

To measure resistance:

1. Ensure the circuit or component is de-energized before measuring resistance.
2. Connect the test leads as described in Section 4.2.
3. Rotate the function dial to Ω (resistance).
4. Connect the test probes across the component.
5. Read the resistance value on the display.

5.6 Continuity Test

To perform a continuity test:

1. Ensure the circuit or component is de-energized.
2. Connect the test leads as described in Section 4.2.
3. Rotate the function dial to the continuity position (often shared with resistance, indicated by a speaker icon).
4. Connect the test probes across the component or wire.
5. The meter will emit an audible tone if continuity is detected (resistance below a certain threshold).

5.7 Zero Function (DC Measurements)

The “ZERO” button is primarily used for DC current measurements. Before taking a DC current reading, with the clamp jaw open and no conductor inside, press the “ZERO” button to eliminate any residual offset and ensure accurate readings.

5.8 Data Hold Function

Press the “HOLD” button to freeze the current reading on the display. This is useful for taking readings in hard-to-see locations. Press “HOLD” again to release the reading and return to live measurement.

6. Maintenance

6.1 Cleaning

To clean the meter, wipe it with a damp cloth and a mild detergent. Do not use abrasives or solvents. Ensure the meter is completely dry before use.

6.2 Battery Replacement

When the low battery indicator appears on the display, replace the batteries promptly to maintain measurement accuracy. Refer to Section 4.1 for battery installation instructions.

6.3 Storage

If the meter is not used for an extended period, remove the batteries to prevent leakage and damage. Store the meter in a dry, cool environment, away from direct sunlight and extreme temperatures.
