3 Fix the weighing plunger in place
￭ Once the height of the weighing plunger has been adjusted cor-
rectly, raise the sample rack.
￭ Secure the position of the weighing plunger with the fixing nut.
Tighten the nut with either a wrench or an adjustable wrench.
Note
The tightening of the fixing nut is important, because the weigh-
ing plunger could become loose as a result of the rotational move-
ments of the rack and change its height. This could lead to weigh-
ing errors, the origins of which would not be readily recognizable.
Check the position of the weighing plunger at regular intervals.
4 Connect the mains cable
￭ Reconnect the mains cable of the Sample Processor.
