1 Safety ! 1.1 Representations and symbols ! ! ! !! Important instructions, which involve safety, are highlighted with the appropriate mark: 1.2 Safety recommendations ! ! ! ! ! ! ! When using the weighing equipment in surroundings with increased safety requirements, the corresponding regulations must be observed. The weighing machine may only be used with the power adapter supplied exclusively for use with the weighing machine.
! Your Weigh Bar weighing machine is rated to IP65. The IP rating system • IP stands for Ingress Protection • The rating’s first digit e.g. IP65 relates to the ingress protection against dust (6 means dust tight, see the table below) • The second digit e.g.

3 Getting started with your weighing machine ! 3.1 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 re-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.
! ! !! The weighing machine is delivered in partly dismantled condition. Assemble the individual components in the following sequence: − − Place the unit holder in position. Insert the power adapter cable plug into the socket at the rear of the balance. 3.4 Choice of a suitable location ! The environment in which your weighing machine is used is very important. Air movement, temperature changes, vibrations, direct sunlight, etc. all influence the performance of high precision weighing machines.
!! !! !! Step1: Connect the cable to the load cell and plug the metal connectors under power off condition. ! ! ! ! ! Step 2: Adjust the four scale feet horizontally. ! ! ! ! ! ! ! ! ! ! ! ! 3.6 Calibrating the weighing machine ! Since the Earth’s gravity is not the same everywhere, each balance must be adjusted to compensate for the gravity differences at each location in accordance with the underlying physical weighing principles.
! In order to ensure exact measurements, it is recommended that the balance should be calibrated regularly using a known external calibration weight (see Section 5 below).

! 5 Calibration - Using an External Calibration Weight Calibration is generally required when the weighing machine is initially installed or if the weighing machine is moved to a substantial distance from the original location. 30 minutes of warming up of the scale is always needed before initial calibration. A reminder when operating our larger capacity scales: ! The WB series are calibrated at the factory. Usually no recalibration is necessary unless major inaccuracies are observed.
6 Maintenance and 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. ! ! ! See Section 1.3 above regarding IP65. The scale may be washed down.
7 Transport, storage ! 7.1 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). 7.
