2. Safety Information
Please read and understand all safety warnings and operating instructions before using this scale. Failure to do so may result in injury or damage to the equipment.
- Power Source: Use only the supplied AC adapter or approved batteries. Ensure the power outlet matches the adapter's specifications.
- Environment: Operate the scale on a stable, level surface. Avoid extreme temperatures, high humidity, and direct sunlight. While the scale is washdown capable, do not submerge the entire unit in water.
- Handling: Do not drop the scale or subject it to excessive shock. Avoid placing objects heavier than the maximum capacity (6 lb / 3000g) on the platform.
- Cleaning: Disconnect power before cleaning. Use mild detergents and avoid abrasive cleaners or solvents that could damage the finish or internal components.
- Maintenance: Refer all servicing to qualified personnel. Do not attempt to open or repair the scale yourself.
3. Setup
Follow these steps to set up your Rice Lake RLP-6S scale:
- Unpacking: Carefully remove the scale and all accessories from the packaging. Retain the packaging for future transport or storage.
- Placement: Place the scale on a firm, level, and stable surface, free from vibrations. Ensure adequate space around the scale for operation and cleaning.
- Power Connection:
- AC Power: Connect the supplied AC adapter to the power input port on the scale and then plug it into a suitable electrical outlet.
- Battery Power (Optional): If using batteries, ensure they are correctly installed in the battery compartment according to polarity markings.
- Initial Power On: Press the POWER button to turn on the scale. The display will perform a self-test and then show "0.000" or "0.0" depending on the selected unit.
- Leveling: The scale should be level for accurate readings. Check the bubble level (if present) and adjust the feet if necessary.
4. Operating Instructions
This section details the basic functions of your RLP-6S scale.
4.1. Button Functions
- POWER: Turns the scale on or off.
- ZERO / +0+: Sets the display to zero. Use this button to zero out the scale before placing an item, or to re-zero if the display drifts slightly.
- TARE: Used to subtract the weight of a container. Place an empty container on the platform, press TARE, and the display will return to zero. Then add the item to be weighed. The display will show the net weight of the item.
- UNITS: Cycles through available weighing units (e.g., ounces (oz), pounds (lb), grams (g)). The active unit will be indicated on the display.
4.2. Basic Weighing
- Turn on the scale by pressing the POWER button.
- Wait for the display to stabilize at "0.000" or "0.0". If it does not, press the ZERO button.
- Place the item to be weighed gently on the center of the stainless steel platform.
- Read the stable weight displayed on the LED screen.
- To change units, press the UNITS button until the desired unit (oz, lb, or g) is indicated.
4.3. Tare Function
- Turn on the scale and ensure it displays "0.000".
- Place an empty container (e.g., bowl, tray) on the weighing platform. The display will show the container's weight.
- Press the TARE button. The display will return to "0.000" and the "Net" indicator will illuminate, signifying that the container's weight has been tared out.
- Add the substance or item to be weighed into the container. The display will now show only the net weight of the added item.
- To clear the tare, remove the container from the platform. The display will show a negative value equal to the container's weight. Press TARE again to return the display to "0.000".
5. Maintenance
Proper maintenance ensures the longevity and accuracy of your Rice Lake RLP-6S scale.
- Cleaning: The RLP-6S is a washdown scale. Disconnect the AC adapter before cleaning. Use a damp cloth with mild soap or detergent to wipe down the stainless steel platform and housing. Avoid using abrasive pads, harsh chemicals, or solvents. Ensure no liquid enters the display or button areas excessively, despite its washdown design. Allow the scale to air dry completely before reconnecting power.
- Storage: When not in use for extended periods, store the scale in a clean, dry environment, away from direct sunlight and extreme temperatures. If using battery power, remove batteries to prevent leakage.
- Calibration: While the scale is factory calibrated, periodic calibration with certified weights may be necessary to maintain accuracy, especially after significant temperature changes or prolonged use. Refer to the full technical manual or contact Rice Lake support for calibration procedures.
