Operation Manual
Thank you for purchasing the indicator. Please read all operating instructions
carefully before use and keep the following points in mind:
* Avoid lengthy exposure to extreme heat or cold, your scale works best when operated
at normal room temperature. Always allow the scale to acclimate to a normal room
temperature before use
* Allow sufficient warm up time. Turn the scale on and wait for a few minutes if
possible, to give the internal components a chance to stabilize before weighing.
* These electronic scales are precision instruments. Do not operate near an in-use cell
phone, radio, computer or other electronic device. These devices emit RF and can
cause unstable scale readings. If your scale ever performs poorly, try moving the scale
to a different room or location.
* Avoid using in condition of heavy vibration and airflow.
* Read the weight reading in short time after loading. The output signature of load cell
and A/D may be little influenced after weighing for a long time.
