1. Measurement Probe/Sensor
2. LCD Display
3. um/mm/mils Button: Changes measurement units.
4. AUTO F/NF Button: Toggles between automatic substrate detection and manual selection (Ferrous/Non-Ferrous). Also used for calibration.
5. AUTO OFF Button: Power on/off.
6. ZERO CAL Indicator (on screen)
7. Battery Compartment (on the back)

Setup

1. Battery Installation

1. Locate the battery compartment on the back of the device.
2. Open the battery cover.
3. Insert two (2) 1.5V AAA batteries, ensuring correct polarity (+/-).
4. Close the battery cover securely.

2. Powering On/Off

Press and hold the "AUTO OFF" button to power the device on or off. The LCD display will illuminate upon power-on.

Operating Instructions

1. Basic Measurement

1. Power on the device.
2. Place the measurement probe firmly and perpendicularly onto the coated surface you wish to measure.
3. The device will automatically detect the substrate type (Fe for Ferrous, NFe for Non-Ferrous) and display the coating thickness on the LCD.
4. Lift the device from the surface to take another measurement.

2. Changing Measurement Units

Press the "um/mm/mils" button to cycle through the available measurement units: micrometers (um), millimeters (mm), and mils.

3. Calibration

Regular calibration ensures measurement accuracy. The HW300-MINI supports automatic zero-point calibration and multi-point calibration.

Automatic Zero-Point Calibration

1. Ensure the device is powered on.
2. Place the probe directly onto a bare (uncoated) metal substrate (e.g., the included substrate plate).
3. Press and hold the "AUTO F/NF" button until "ZERO CAL" appears on the screen, then release. The device will calibrate to zero.

Multi-Point Calibration (using calibration films)

1. Perform zero-point calibration first.
2. Place a known thickness calibration film (e.g., 0.50mm) onto the bare metal substrate.
3. Place the probe onto the calibration film.
4. Adjust the displayed value to match the film's thickness using the "um/mm/mils" and "AUTO F/NF" buttons (refer to the on-screen prompts or detailed manual for specific button combinations for adjustment).
5. Repeat for other calibration films if higher accuracy across a range is required.

4. Data Display Interpretation

The LCD displays various information:

• Current Measurement: The largest number on the screen.
• Units: um, mm, or mils.
• Substrate Type: Fe (Ferrous) or NFe (Non-Ferrous).
• AUTO: Indicates automatic substrate detection mode.
• MAX: Maximum recorded thickness.
• MIN: Minimum recorded thickness.
• AVG: Average recorded thickness.
• DIF: Difference between MAX and MIN.
• NUM: Number of measurements taken.

Maintenance

Cleaning

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the probe tip is clean and free of debris for accurate readings.

Storage

When not in use for extended periods, remove the batteries to prevent leakage. Store the device in its original packaging or a protective case in a cool, dry place.

Troubleshooting

• Device does not power on: Check battery installation and ensure batteries are not depleted. Replace if necessary.
• Inaccurate readings: Perform zero-point and multi-point calibration. Ensure the probe is clean and placed firmly on the surface. Verify the substrate is clean and free of rust or debris.
• Display shows "Err": This may indicate a measurement error or an issue with the sensor. Try recalibrating or restarting the device. If the problem persists, contact support.
