• TOOLTOP ET32 Transmitter Unit
• TOOLTOP ET32 Receiver Unit
• Type-C Charging Cable
• User Manual
• Storage Pouch (may vary by package)

5. Setup and Charging

5.1 Initial Charging

The TOOLTOP ET32 features a rechargeable lithium battery. Before first use, fully charge both the transmitter and receiver units using the provided Type-C charging cable. Connect the cable to a standard USB power adapter (not included) and the charging port on each unit. The charging indicator will show the charging status.

5.2 Powering On/Off

To power on the device, press and hold the power button on both the transmitter and receiver units. To power off, press and hold the power button again. The device also features an auto power-off function to conserve battery life after a period of inactivity.

6. Operating Instructions

6.1 Circuit Breaker Finding (Scan Mode)

This function helps identify the correct circuit breaker for a specific outlet or fixture.

1. Step 1: Learn Mode (Scan Once)

   Plug the transmitter unit into the outlet you wish to test. Turn on the receiver unit. Press the 'SCAN' button on the receiver. Move the receiver along the circuit breakers in the electrical panel. The receiver will emit a sound or visual indication as it learns the circuit. Ignore initial indications during this learning phase.

2. Step 2: Locate Mode (Scan Again)

   After the learning phase, press the 'SCAN' button again. Move the receiver along the circuit breakers. The receiver will now pinpoint the correct circuit breaker with clear flashing lights and beeps, indicating the specific breaker connected to the tested outlet.

6.2 GFCI Testing

The GFCI test function measures the trip time of Ground Fault Circuit Interrupter outlets.

1. Plug the transmitter unit into the GFCI outlet to be tested.
2. Ensure the transmitter is powered on.
3. Press the 'GFCI' button on the transmitter. The LCD will display the time taken for the GFCI to trip in seconds.
4. A 'CORRECT' indication signifies normal operation. Refer to the 'Understanding Display Indications' section for other messages.

6.3 NCV (Non-Contact Voltage) Testing

The NCV function allows for detection of live AC voltage without direct contact.

1. Turn on the receiver unit.
2. Select the NCV mode on the receiver.
3. Bring the tip of the receiver close to the wire, outlet, or electrical component you wish to test.
4. The receiver will indicate the presence of AC voltage through visual (flashing light) and audible (beeping) signals. The intensity of the signal may vary with voltage strength and proximity.

6.4 Wiring Test and Voltage Measurement

When the transmitter is plugged into an outlet, it automatically performs a wiring test and displays the measured voltage on its VA color screen. The display will indicate the wiring status (e.g., CORRECT, OPEN GROUND, HOT/GND REV) and the AC voltage.

6.5 Adjustable Sensitivity

The receiver unit features adjustable sensitivity for the NCV and circuit breaker finding functions. This allows for fine-tuning to avoid false positives or to detect signals in challenging environments. Refer to the receiver's controls for adjusting sensitivity levels.

6.6 Flashlight Function

The receiver unit includes an integrated LED flashlight. Activate the flashlight by pressing the dedicated button (or a combination of buttons, refer to device markings) to illuminate dark work areas.

7. Understanding Display Indications

The VA color screen on the transmitter provides clear indications of wiring status and test results. Below are common messages and their meanings:
