Adjusting the Lower Middle Stops
Important note:
The lower middle stop cannot be seen while you are adjusting it; thus you
need to go by sound in checking and finding the correct position.
– Place the scale on a stable surface, so that you can reach both stop
screws (113) from underneath the scale.
– Place a load equal to the maximum capacity of the scale plus 1 kg on
the middle of the weighing pan.
– Unscrew the stop screws (113) until you can hear that the stop is free.
– Turn one of the screws (113) slowly against the stop while checking the
distance by pressing down on the load.
– Continue this procedure until you have found the position in which the
screw (113) touches the stop (the sound of the stop can no longer be
heard).
Important note:
After setting the first screw correctly, turn it back by ¼ turn in order to adjust
the second screw.
- Follow the same procedure to adjust the second screw (113).
- After the second stop screw (113) is in the correct position, readjust the
first screw by ¼ turn so that it is back in the correct position as well.
- Once both screws (113) are adjusted properly, remove the scale from its
raised position.
