Getting started Unpacking the equipment The machine is delivered in an environmentally-friendly carton, specifically developed for this precision instrument, which provides optimum protection for the balance during transportation. We suggest that you retain the original packaging in order to avoid transportation damage if shipping or transporting the balance and to allow the unit to be stored in the best conditions if it is out of operation for an extended period.

Assembling your weighing machine The weighing machine is delivered in partly dismantled condition. Assemble the individual components in the following sequence: − Place the unit holder in position and add the weighing pan − Insert the power adapter cable plug into the socket at the rear of the balance. Choice of a suitable location The environment in which your weighing machine is used is very important.

Leveling the weighing machine To function properly, the balance must be precisely horizontal. The balance is fitted with one bubble level. and adjustable feet for level-control, with the aid of which it is possible to compensate for small height differences and / or any unevenness in the surface on which the balance is positioned.

Calibration Using an External Calibration Weight Calibration is required when the weighing machine is initially installed or if the balance is moved to a substantial distance from the original location or if ambient conditions change considerably. 30 minutes’ warm-up of the balance is always needed before weighing and calibration.
Maintenance & Service The weighing machine must be treated carefully and cleaned regularly. It is a precision instrument. For maintenance-work, the balance must be separated from the power supply (remove power adapter plug from socket). Also ensure that the balance cannot be reconnected to the power supply during the work by a third party.
Transport & Storage Transportation and shipping of the weighing machine Your weighing machine is a precision instrument. Treat it carefully. Avoid shaking, severe impacts and vibration during the transportation. Take care that there are no marked temperature fluctuations during the transportation and that the weighing machine does not become damp (condensation).
