4.4. Care & Maintenance
Please read all operating instructions carefully before use. Scales are precision instruments and should
always be handled with proper care. To ensure years of reliable service, keep these simple tips in mind:
• Do not exceed the scales maximum capacity. Overloading your scale can permanently damage it!
• Avoid exposure to extreme heat or cold. Scales perform best at normal room temperature. If temperatures
have changed dramatically, recalibration may be necessary.
• Allow your scale to warm up for three hours before performing initial calibration.
• Store your scale in a clean, dry location. Dust, dirt, and moisture can accumulate on the weighing sensors
and electronics causing inacuracy or malfunction.
• Avoid static electricity sources, as they can have an adverse effect on the weighing sensors.
• Always weigh on a flat and level surface, free from vibrations and drafts. The corner of a room is usually the
most stable.
• Gently apply all items to be weighed. Do not drop items onto the weighing platform.
• Avoid dropping your scale. The warranty does not cover damage due to rough treatment or overload.
• Keep the weighing pan clean using a soft cloth. Do not use harsh chemicals.
4.5. Troubleshooting
Problem:
The display shows “F - - -”
Solution:
1. The weight on the scale is in excess of the rated capacity. Remove the excess weight.
2. The balance may be improperly calibrated. Try recalibration (Section 3.7)
Problem:
The display fluctuates.
Solution:
1. Vibration or wind is interfering with the measurement. Try using the balance in a more
stable location.
2. Electronic balances can be affected by static electricity and radio waves. Make sure the
area is static free and away from any radio wave emitting devices such as cordless phones
and computers.
3. The item on the platform is in motion. Wait for it to stabilize or try supporting it with
whatever means is convenient.
Problem:
The scale is weighing inaccurately.
Solution:
1. The scale requires recalibration. Follow the steps in Section 3.7.
2. The TARE feature has been used improperly. Remove the items and try again.
3. The balance is not level. Adjust the leveling feet until the bubble level is centered.
4. Battery power may be low (the “ ” symbol will appear). Replace the batteries.
