4. Setup
4.1 Battery Installation
- Locate the battery compartment cover on the back of the device.
- Slide or unclip the cover to open the compartment.
- Insert the required batteries (e.g., 2 x AAA batteries) according to the polarity indicators (+/-) inside the compartment.
- Close the battery compartment cover securely.
4.2 Initial Power-On
Press and hold the Power button (usually marked with ⑂ or ⑂/⑃) for a few seconds until the display illuminates. The device will perform a self-test and then enter measurement mode.
4.3 Calibration
For accurate measurements, it is crucial to calibrate the gauge before first use and periodically thereafter, especially when measuring different materials or after significant temperature changes. The HW-400 supports zero calibration.
- Ensure the gauge is powered on.
- Place the probe firmly on the bare, uncoated metal substrate block (ferrous or non-ferrous, depending on your measurement).
- Press the ZERO CAL button. The display should show "0.00" or a value very close to zero, indicating successful calibration.
- For multi-point calibration (if supported), refer to the specific instructions for using the provided calibration films.
5. Operating Instructions
5.1 Taking a Measurement
- Ensure the measurement surface is clean, dry, and smooth.
- Gently place the probe of the gauge perpendicular to the coated surface.
- Apply slight, steady pressure. The measurement will typically be displayed instantly.
- Lift the gauge from the surface to prepare for the next measurement.
5.2 Understanding Display Modes and Readings
The HW-400 display provides various indicators and measurement units:
- AUTO NFE: Automatic detection of substrate type (Ferrous or Non-Ferrous).
- SNG CNT: Single measurement count.
- um / mils: Measurement units. Press the UNIT button to switch between micrometers (um) and thousandths of an inch (mils).
- MAX / MIN / AVG / DIF: Maximum, Minimum, Average, and Difference readings from a series of measurements. These statistics are typically displayed below the current measurement.
- NUM: Number of measurements taken in the current series.
- ZERO CAL: Indicates the zero calibration status.
- Battery Indicator: Shows the current battery level.
5.3 Button Functions
- Power Button (⑂/⑃): Press and hold to turn the device ON/OFF.
- LIGHT Button (💡): Toggles backlight ON/OFF.
- AUTO OFF Button: Activates or deactivates the automatic power-off feature to conserve battery life.
- UNIT Button: Switches between measurement units (um/mils).
- ZERO CAL Button: Initiates zero calibration.
6. Maintenance
6.1 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.
6.2 Storage
When not in use for extended periods, remove the batteries to prevent leakage. Store the gauge in its protective pouch or case in a cool, dry place, away from direct sunlight and extreme temperatures.
6.3 Battery Replacement
When the battery indicator shows low power, replace the batteries promptly to ensure consistent performance. Refer to Section 4.1 for battery installation instructions.
7. Troubleshooting
If you encounter issues with your HW-400 Coating Thickness Gauge, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Check battery polarity; replace batteries. |
| Inaccurate readings. | Gauge not calibrated; dirty probe tip; unstable surface. | Perform zero calibration; clean probe tip; ensure stable measurement. |
| Display shows "Err" or similar. | Measurement out of range; sensor error. | Ensure measurement is within specified range; restart device. If error persists, contact support. |
| Buttons are unresponsive. | Device frozen; low battery. | Remove and reinsert batteries; replace batteries. |
If the problem persists after attempting these solutions, please contact RIEMRITEMRE customer support.
