Setup
1. Battery Installation
- Locate the battery compartment on the underside of the scale.
- Open the battery compartment cover.
- Insert the two included AAA Lithium batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
2. Placement
Place the scale on a hard, flat, and stable surface to ensure accurate readings. Uneven surfaces can lead to measurement inaccuracies.
Operating Instructions
Power On/Off
- To turn the scale ON, press the ON/OFF button. The display will show "88888" and then "0.0g" (or the last used unit).
- To turn the scale OFF, press and hold the ON/OFF button for a few seconds until the display turns off. The scale will also automatically shut off after a period of inactivity to conserve battery life.
Changing Weighing Units (MODE)
- With the scale powered on, press the MODE button to cycle through the available weighing units: grams (g), ounces (oz), pennyweight (dwt), and troy ounces (ozt).
- The selected unit will be indicated on the LCD display.
Tare Function
- To weigh items in a container, first place the empty container on the weighing platform.
- Press the TARE button. The display will reset to "0.0g" (or the current unit).
- Now, place the items to be weighed into the container. The display will show the net weight of the items.
LCD Backlight
- Press the LIGHT button to toggle the LCD backlight on or off. This feature is useful in low-light conditions.
Calibration
For optimal accuracy, digital scales may require periodic calibration. The ProScale LC-300 scale can be calibrated using a 300g calibration weight (not included with the scale). Refer to the manufacturer's specific calibration procedure if you wish to perform this operation.
Maintenance
Cleaning
To clean the scale, wipe it with a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water. Ensure no liquids enter the internal components. The design of the scale minimizes deep crevices, making it easy to clean.
Storage
Store the scale in a cool, dry place, away from dust and direct sunlight. If storing for extended periods, it is recommended to remove the batteries to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate readings | Low batteries; unstable surface; scale overload; need for calibration. | Replace batteries; place on a flat, stable surface; ensure weight is within 300g capacity; consider calibration with a 300g weight. |
| Scale does not turn on | Dead or incorrectly installed batteries. | Check battery polarity; replace batteries with new AAA Lithium batteries. |
| Display shows "EEEE" or "O_Ld" | Scale is overloaded. | Remove excess weight immediately. Do not exceed 300g capacity. |
| Plastic cover interferes with weighing | Cover not properly aligned or removed. | Ensure the protective plastic cover is fully removed or correctly positioned so it does not press on the weighing platform. |
