3.2.2 Additional Weight of 700 grams
Figure 13: additional weight
It is possible to equip the Vicat needle devices with an additional weight of 700 grams, to increase the
weight of the drop rod to 1 Kilogram. In this case it is recommended to purchase the complete set of drop
rod with additional weight for 1 kg and a harder stoper buffer which stops the drop rod (1 kg) above the
glass plate, whereas the 300 g drop rod then falls onto the glass plate.
To mount the additional weight please put the device into maintenance position, as described in section
Then open the flap, as described in section
The drop rod is lowered, to allow the additional weight to be put on the top of the drop rod.
Leave maintenance position.
Note
If the drop rod is caught by the buffer above the glass plate, the detection of broken
needle no longer works! The zero heights may only be measured with a drop rod
that falls on the glass plate! If the device is used with the drop rod for 1 kg, the soft
standard stopper (rubber buffer) must be replaced by the harder stopper (which is
supplied with the 1 kg drop rod) (
.)! The harder stopper can also be used with
the lighter drop rods (300 and 100g).
Note
Before taking the additional weight into operation, please check the correct fit on the
top of the drop rod.
Take out the drop rod and put the additional weight on it.
Caution!
A wrong position of the additional weight (too high on the drop rod), leads to a jam
of the Y-axis. It is possible that the seat of the drop rod is not adjusted correctly any
more. In this case, it has to be readjusted.
