Although the JSR is designed to be extremely durable. It’s important that you never overload or drop/shock the scale. Scales
are delicate instruments and unlike Cellular phones,scales have delicate sensors that determine how much an item weighs. If
you drop or shock your scale, these sensors “feel” the shock and are sometimes destroyed. This happens with all digital scales.
We design our scales to be as resistant to shock or drops as possible. However there is no way for us to protect 100% against
load cell or sensor damage. A well-treated scale will provide years of reliable and accurate weighing. However an abused scale
will only work until it’s sensors are damaged.
