Product Overview
The Radwag WPT 60H3 is a robust waterproof platform scale designed for use in humid environments and direct contact with water. It features a durable stainless steel construction and an LCD display for clear readings.
- Waterproof Design: Engineered to operate reliably in wet conditions.
- Durable Construction: All structural elements, including the weighing platform, are made from OH18N9 stainless steel.
- Clear Display: Equipped with a backlit LCD indicator (PUE C/31H series) for easy readability.
- Flexible Installation: The indicator can be pillar-mounted or optionally installed on a wall using a cable.
- Power Options: Operates on mains power (100-240V AC) and includes a battery for portable use.
- Connectivity: Features an RS232 communication interface as standard.
Setup Instructions
- Unpacking: Carefully remove all components from the packaging. Inspect for any signs of damage during transit. Retain packaging for future transport or storage.
- Assembly:
- Attach the pillar to the platform base if not already assembled. Ensure it is securely fastened.
- Mount the PUE C/31H indicator onto the pillar. If wall-mounting is preferred, use the provided cable and appropriate wall-mounting hardware (not included) to secure the indicator.
- Placement: Place the scale on a stable, level surface, free from vibrations, drafts, and direct sunlight. Ensure adequate space around the scale for operation and maintenance.
- Power Connection: Connect the scale to a suitable mains power outlet (100-240 V AC, 50/60 Hz) using the provided power cable. The internal battery will charge automatically. The scale can also operate on battery power for approximately 45 hours on average.
- Initial Power On: Press the power button on the indicator. Allow the scale a few minutes to warm up and stabilize before use.

Operating Instructions
- Power On/Off: Press the ON/OFF button to turn the scale on or off.
- Zeroing the Scale: Before placing any item on the weighing pan, ensure the display reads "0.000 kg" (or appropriate unit). If not, press the ZERO button to reset the display to zero.
- Weighing an Item:
- Place the item gently in the center of the stainless steel weighing pan.
- Wait for the reading to stabilize. The weight will be displayed on the LCD.
- Remove the item from the pan.
- Tare Function: To weigh an item in a container:
- Place the empty container on the weighing pan.
- Press the TARE button. The display will reset to "0.000 kg", effectively subtracting the container's weight.
- Add the item to be weighed into the container. The display will show only the net weight of the item.
- To clear the tare value, remove the container and item, then press TARE again.
- Unit Conversion: If your scale supports multiple units, refer to the indicator's specific button layout for unit conversion (e.g., kg to lb). This model primarily uses kilograms.
Maintenance
- Cleaning:
- Due to its IP67/68/69 protection class and stainless steel construction, the scale can be cleaned with water and mild detergents.
- Do not use abrasive cleaners or solvents that could damage the display or surfaces.
- Ensure the scale is disconnected from mains power before thorough cleaning.
- Wipe dry with a soft cloth after cleaning.
- Battery Care:
- To maximize battery life, fully charge the battery periodically, especially if the scale is not used for extended periods.
- Avoid completely draining the battery frequently.
- Calibration: Regular calibration is recommended to maintain accuracy. Refer to the specific calibration procedure for the PUE C/31H indicator, which may require specialized weights and technical knowledge. Contact Radwag support or an authorized service provider for calibration services.
- Storage: When not in use for long periods, store the scale in a dry, clean environment within the specified operating temperature range (-10 °C to +40 °C).
Troubleshooting
- Scale does not power on:
- Check if the power cable is securely connected to both the scale and the mains outlet.
- Ensure the mains outlet is functional.
- If operating on battery, ensure the battery is charged. Connect to mains power and allow time for charging.
- Inaccurate readings:
- Ensure the scale is placed on a stable, level surface.
- Check for any obstructions under or around the weighing pan.
- Verify that the scale has been zeroed before weighing.
- Avoid placing items off-center on the pan.
- Environmental factors like strong air currents or vibrations can affect accuracy.
- Consider if calibration is required.
- Display shows error message:
- Consult the specific error codes in the PUE C/31H indicator's user manual (if available separately).
- Try powering the scale off and on again.
- If the error persists, contact customer support.
