OPERATION AND ADJUSTMENT
ADJUSTMENT OF BALANCE IN ZEROS
1. Verify that the scale is situated on a firm and steady surface. Go
up and down on to the scale several times so that all parts of it are
levelled and aligned.
2. Without any weight on the scale, set both counterweights in their
corresponding zeros (figure 4). The pointer of the scale must move
freely up and down, without touching the upper or the lower part
of the limitative rectangle.
3. If the pointer does not move the same distance up and down wit
respect to the centre of the limitative rectangle, move the mobile
counterweight of the graduated rule (figure 4).
