Assembly & Installation The weighing scale is delivered in a partly dismantled condition. Assemble the individual components in the following sequence:  Place your machine on a level, clean, and dry surface to obtain accurate readings.  Place the plastic platter on top of the scale, flat side facing up so the platter sits firmly on the machine with the four “legs” inserted into the corresponding four receptacles.  Place the stainless steel platter on top of the plastic platter with the flat side facing up. Connecting the AC Adapter The following Safety recommendations must be observed when connecting the balance The Scale should only be connected to the mains voltage socket with the power adapter supplied. Check before connecting the power adapter to the mains socket, that the operating voltage stated on the power adapter complies with the local mains voltage. If the operating voltage is not the same as the mains voltage, the power adapter must not be connected to the mains socket and contact customer service. Placement of Scale The location in which the scale is placed is very important in order for the scale to work to its full potential. Certain conditions can affect the capabilities of the scale, conditions like: the presence of air flow, variations in temperature, and direct sunlight. Please follow the recommendations given below in choosing a location to place your scale.  Place the scale on a solid, firm and preferably vibration-proof, horizontal base  Make sure that the weighing machine cannot be shaken or knocked over  Protect from direct solar radiation  Avoid drafts and excessive temperature fluctuations  Avoid placing the scale near or on any magnetic surfaces. The scale is fitted with one bubble level, and adjustable feet for level-control that allow for small height differences or any unevenness in the surface on which the balance is placed.

The screw feet must be adjusted so that the air bubble is precisely in the center of the sight glass of the bubble level. Place the scale horizontally and keep the bubble inside the bubble level aligned with the circle (Fig.1). In order to get exact measurements, the balance must be carefully leveled after each re-location. Fig. 1 Correct leveling with the aid of the bubble level and adjusting feet.
