Adjustment Of The Counter Weight To The Intended Load - Sartorius Stedim Biotech CERTOMAT Tplus Bedienungsanleitung

2.4.2 Adjustment of the Counter Weight to the Intended
Load
Upon delivery the CERTOMAT® Tplus is preadjusted for
a load of 10 kg. If the intended load is different from
this, the counter weight has to be readjusted
correspondingly. Thus the vibrations, which may occur
during operation, can be minimized.
1. Weigh the completely equipped tray with all shaking
containers attached.
2. Switch off the CERTOMAT® Tplus at the main switch.
3. To adjust the counter weight with the variable tool
for the load open the front flap under the glass doors
downwards. The front flap is fixed with magnets.
The variable tool is located behind this flap.
4. Turn the shaking table by hand to its rearmost
position.
5. Block the drive of the shaking table by putting the
delivered hexagon socket screw key through the
boring of the shaking table (Fig. 9 and 10, pos. 4).
Carefully turn the shaking table until the drive has
totally blocked.
