III.2.4 Computer Connection
If the R/S-CPS+ Rheometer has to be used in “REMOTE” mode with a PC (Rheo 3000
program package) or with serial data-terminal for data-logging, the RS232 cable needs to
be connected to the 25 pin connector labelled “RS232” on the back of the instrument.
- Turn the R/S-CPS+ Rheometer off with the “POWER” switch at the back of the
instrument.
- Turn the computer system off.
- Connect the rheometer data cable to the 25 pin port labelled “RS232” on the back
of the R/S CPS+ Rheometer.
- Connect the Peltier data cable to the port labelled “RS232/Peltier” on the back of
the P-TS control unit.
- Turn the R/S CPS+ Rheometer and your computer system on again.
You must use the computer cable supplied by Brookfield - other cables will not work!
III.3 Connecting the Temperature Control Device
The following devices are used to provide temperature control:
• A Bath/Circulator for the temperature range -20°C to +250°C.
• The Peltier temperature control device for the temperature range 0°C to +135°C or
+20°C to +180°C.
III.3.1 Connecting a Bath/Circulator
Hose connections are required to connect a bath/circulator to the R/S CPS+ Rheometer. The
hoses for the bath/circulator are connected by means of quick connect couplings. When
viewing the instrument from the front, the supply is at the front connection (connected to
the bath outlet) and the discharge is the rear connection (to be connected to the bath inlet).
In this case, the bath water/oil enters in the middle of the plate and spreads evenly towards
the plate periphery.
To connect the hoses, push the coupling sleeve slightly back, insert the hose connecting piece
and let the coupling go. It will fasten the hose (without screwing and turning) by locking
it in place. Check whether the hose connection is secure by pulling gently.
The R/S CPS+ Rheometer can only be used without additional
cooling at temperatures up to +140°C. For operation with higher
temperatures (+140°C to +250°C), water has to be fed into the cooling
flange!
The water in the Bath Circulator should be changed annually!
