4. Setup
4.1 Battery Installation
The Fluke T5-1000 requires 2 AAA batteries (included). To install, locate the battery compartment on the rear of the device, open it, insert the batteries observing polarity, and close the compartment securely.
4.2 Attaching Test Leads
Connect the red test lead to the 'V' or 'Ω' input and the black test lead to the 'COM' input. Ensure the detachable SlimReach probe tips are securely attached to the test leads.

The detachable SlimReach probe tips provide versatility and access to tight spaces.
5. Operating Instructions
5.1 Power On/Off
Rotate the central dial to the desired measurement function to power on the device. Turn the dial to 'OFF' to power off and conserve battery.
5.2 Voltage Measurement (AC/DC Automatic Selection)
Set the dial to 'V'. The tester automatically detects AC or DC voltage. Connect the probe tips to the circuit points you wish to measure. The reading will appear on the digital display.

The tester's design allows for safe and efficient voltage measurements in complex electrical systems.
5.3 Current Measurement (OpenJaw)
Set the dial to 'A'. Place the open jaw around a single conductor (wire) to measure AC current without breaking the circuit. The current reading will be displayed.

The OpenJaw feature enables non-contact current measurement, enhancing safety and convenience.
5.4 Resistance (Ohms) and Continuity
Set the dial to 'Ω'. For resistance, connect the probes across the component. For continuity, touch the probes to the two points you want to test; a beeper will sound if continuity is present.
5.5 Hold Function
Press the 'HOLD' button to freeze the current reading on the display. This is useful in tight spaces or when you need to record a reading after removing the probes. Press 'HOLD' again to release.

6. Maintenance
6.1 Cleaning
Clean the tester's casing with a damp cloth. Do not use abrasive cleaners or solvents. Keep the display clean and free of debris.
6.2 Battery Replacement
Replace batteries when the low battery indicator appears on the display. Refer to the 'Setup' section for battery installation instructions.
6.3 Probe Inspection
Regularly inspect test leads and probe tips for any signs of damage, such as cuts, cracks, or frayed insulation. Replace damaged components immediately to ensure safety and accurate readings.
7. Troubleshooting
7.1 No Display/Power
- Check battery levels and ensure they are correctly installed.
- If the device has been idle, it might be in auto-off mode; rotate the dial to reactivate.
7.2 Inaccurate Readings
- Ensure probes are making good contact with the circuit.
- Verify the correct function is selected on the dial.
- Check for damaged test leads or probe tips.
7.3 Continuity Beeper Not Sounding
- Ensure the dial is set to the continuity (Ω) function.
- Check for open circuits or high resistance between the test points.
