Manually controlled accessories
Manually controlled accessories may also be connected to the optical unit. These accessor-
ies do not have an automated or manual software control, but will be controlled directly
from the control interface on the accessory itself.
Like the automatic controlled dispersion units, manual accessories are selected from the
SOP Editor:
1.
On the Home ribbon, select New–SOP from within the Documents group rib-
bon. To edit an existing SOP, choose Open–SOP instead.
2. Complete the SOP Editor as described in the Mastersizer 3000 User Manual.
Hydro SM
The Hydro SM is controlled via the speed control on the front of the controller unit.
Dependant upon the sample being measured and the SOP routine that is followed the
speed of the pump can be varied between 350 and 3500 rpm. The monitored speed is
shown on the front panel display.
