Like all our scales, the Pearl S is intended for indoor use. We recommend not storing the scale near any equipment/instrument which contains magnets and to avoid places where room temperatures are unstable.
Even when the scale is off, there should be nothing heavier than the heatpad on top. This can engage the load beam and shorten its lifespan or over-capacitate it even when the scale is off.
When traveling, we recommend using our Pearl traveling case.
