IV. Environment, handling, cleaning and maintenance In this chapter you get information concerning environment, handling, cleaning and maintenance of your R/S Rheometer. IV.1 Operating environment, Storage Find comfortable, convenient working place where you install your R/S Rheometer. It must be enough room for installation of the stand, measuring system, measuring substances and peripheral devices (for example printer, computer and thermostat).
Check that any liquid does not penetrate into the housing (e.g. through the instrument connecting plugs) and into the bearings of the measuring drive. It results in the instrument damage! IV.4 Maintenance The R/S Rheometer is designed for long-term operation. Nevertheless we recommend a regular maintenance in one-year cycle by a service engineer of BROOKFIELD or of corresponding representation.
V. Measuring Systems In this chapter you get information concerning use of the measuring system. At present the following measuring system types are supplied: a) Standard measuring systems MS-CC48...CC8 DIN/RC and DG-DIN/RC for measurement without temperature control device FTK-CC consists of: - measuring cup for R/S Rheometer (MB-CC48...MB-CC8/RC and MB-DG/RC) depending on measuring-system - measuring cup bottom - measuring bob (MK-CC48...
Insert carefully the measuring bob into the measuring bob coupling. Pay attention to insert the measuring bob shaft into the measuring bob coupling without impact. Move down the coupling sleeve of the measuring bob coupling (ring covered). Fasten the measuring cup at the measuring cup mounting flange with the help of measuring cup thread. By moving down the stand, immerse the measuring cup into the substance up to the ring mark or up to the point where diameter of measuring cup increases. Fig. 7.
Temperature range max.: 0°C ... +90°C. The cooling device “KE” is required to expand the temperature range to -20°C ...+180°C The temperature sensor Pt100 may be immersed in medium only at 2/3 of the metal rod length! Cable must be always outside the medium. If you want to measure with temperature control, the thermostat must be pre-set at the desired temperature and you should wait till the necessary temperature of the substance is reached (e.g.
To remove the measuring system after the measurement first open the measuring bob coupling and then unscrew the measuring cup screw of temperature control device. Attention: If you have carried out measurements at higher or very low temperatures please take care: Some accessible surfaces can become very hot or cold. Before removing measuring system please wait till the system-surface-temperature equalized to nearly room temperature and allows you to touch the system without danger.
In order to avoid thread backlash, the height adjustment ring must be now obligatory turn through to “0.4” (turn to the right = lift) and then again return back to the 0/red position. Now screw on the inner hexagon screw at measuring bob shaft finger-tight ; this fixes the measuring bob in this position. After rotating the scale mark from 0-/red position to the 0/0 position the cone/plate measuring device is ready for measurements.
VI. Operation and Menue System In the following chapter you will get overview on operations, menue system of R/S Rheometer and measurements, both in manual and PC controlled modes. The menue-system of R/S Rheometer (firmware-version 4.02) is a dual-language system. Following languages are software selectable: • English • German Desired language can be selected via menue item Configuration→Language (if English language is active) or Konfiguration→Sprache (if German language is active).
VI.1 Keyboard BROOKFIELD - menue: previous menue-entry - input: increment value/letter MAIN-menue - Run Single - Run Program - Remote > START/STOP - back to parent menue - break - start of measurement - break of measurement R/S Rheometer - menue next menue entry - input: decrement value/letter ST OK - one digit to the left OK - enter - select - one digit to the right All user inputs are made with help of 6 keys located below LCD-Display. Some of the keys are of multiple use, i.e.
Key-function dependent to executed operation key operation Function of key example Menue goto previous menue-entry (above active one) increment „Utilities“ → „Remote“ Value-input Selection from List list entry above active entry (previous) Menue goto next menue-entry (below active one) decrement Value-input Selection from List list entry below active entry (next) Menue goto previous menue-entry (above active one) one digit to the right Value-input Selection from List list entry above active

Menu handling Because LCD display of R/S Rheometer cannot show simultaneously all menue items, only part of the menue (three entries) is always displayed. Two arrows “>“ at the right side of display inform you, if there are still entries in the menue, either above (the arrow in the 2nd line), or below (the arrow in the 4th line). Currently active (but still not selected) entry is marked by blinking black field (cursor) at the left part of LCD.
• • • Selection of a program or a measuring system you want to edit in “Edit Program” and “Meas. systems”; Answering a request “YES” ↔ “NO”. Selection of a program to start in “Run Program” Keys and move cursor (= pre-selected entry) in the list upwards and downwards. Key OK selects the pre-set entry from the list and ST key interrupts selection from the list (only if possible).
Using now and keys you can move cursor leftwards (rightwards). To process the next digit we push key and get: Input Values: Val.[1/s]: 0200.00 Nr. of MP: 010 Time[s]: 0100 Now we can process the next digit. In order to insert here “9” it’s advisable to decrement once current “0”, rather than to increment it nine times. So, we push key and get: Input Values: Val.[1/s]: 0290.00 Nr.
VI.5 Menue entries (MAIN menue) Menue entries (see Menue System in Chapter 6.2) may either contain submenues (e.g. “Utilities” or “Configuration”) or directly executing of one of the Rheometer’s functions. At Tree Chart in Chapter 6.2 all gray fields without further right branches serve to call functions. Those ones with right branches are submenues. Let us remind keyboard layout from Chapter 6.2.
Output of MPs to: -No output device -Memory <^> Menu Start At this point you either can start a measurement by pressing ST key, or return back to Main menue using key. In this example, we see that the measurement data will be saved in Memory only. No other output device is defined. Output devices are printer or serial interface RS232 of the Rheometer. Selection of these devices is described in Chapter ”Configuration -> Set output mode”.
After measurement, or after a break, the display field for Step indicates “END” or “BREAK”. The Display toggles in intervals of about 4 seconds between last displayed measure point and a measuring end information like this: angezeigt: Break reason or end Type / name of executed progr. Duration until break or end Program end Single mode Total time:100s Total #MP:10 Number of measure points measured By pressing OK key you return to the MAIN-Menue.
If you have passed these points, before starting a measurement, the Rheometer will indicate, where the measure points will be written to. Output of MPs to: -Printer -Memory <^> Menue Start At this point you either can start a measurement by pressing ST key, or return back to Main menue using key. In this example we see, that measurement points will be saved in the memory and will be printed at the printer, so be sure that printer is connected to the Rheometer and ready for operation (=output device).
After measurement, or after a break, the display field for Step indicates “END” or “BREAK”. The Display toggles in intervals of about 4 seconds between last displayed measure point and a measuring end information like this: Break reason or end Type / name of executed progr.

Saving of the Program: (2) TEST Press to save If you push OK key now, the Program will be saved. If you push any other key, the entries are abandoned and previous parameters remain (the current ones, before the edit). VI.6.3 Utilities → Print Programs This function prints the parameters of defined programs in memory at the printer. Be sure that printer is connected to the Rheometer and ready for operation.
After selection of the measuring system, you will be requested to input sequentially: its name, tau_prom and k_gamma. Enter Meas. Sys. #4 Name: CP25 tau_prom: 01.1418 k_gamma: 01.2910 The measuring system name is a alpha-numerical entry, factors tau_ prom and k_gamma are input as numerical entries (see Chapter 6.4). When done, a security request follows, if you really want to save new parameters. PRESS to save Name: CC25 tau_prom: 01.1418 k_gamma: 01.
If you have chosen the output device, you have to select the measuring series to transfer. All available data is displayed in a list. Meas. series counter MEASCOUNT Select Program: - 1;17.10;11:20 - 2;17.10;12:30 - 3;17.10;13:40 Date of measurement Time of measurement After selection of a measurement series, the data of the series will be printed as Table or transferred via the serial interface. After completion of data transfer the Rheometer returns to Utilities Menue. VI.6.
VI.7 Menu entries of the CONFIGURATION menu The Entries: • Set output-mode sets output-mode of measuring data at the time of measurement into the printer or into the serial interface. • Set meascount-mode sets the counter mode (if the MEASCOUNT counter of measuring series will be daily cleared or not). • Reset meascount reduces the MEASCOUNT counter of measuring series by 1. • Set time/date Input of date and time • Set RS232 Param.
b) for output to the serial interface (RS232), the receiving device (normally a PC) is set to the data transfer parameters of the Rheometer (see chapter 6.7.5 “RS232 Parameters”) and ready to receive data. If the receiving side is not ready, the data will not be transmitted or will be transmitted to Null. (See also chapter 6.8 “Serial data transfer”). VI.7.2 Configuration → MeasCount mode Measurement series counter MEASCOUNT is a counter, increasing its count by 1 when starting a measurement.
After setting time and date you will be requested if you want to set clock for new time.

These changed transfer settings will be saved into memory and will remain in the memory also after switching off the instrument. VI.7.
3. The receiver is ready for reception and can (due to sufficient PC and memory capacity) receive or save received data at selected baudrate. It is worth to demonstrate reception with the help of Terminal program under Microsoft Windows. 1. Switch off the Rheometer and PC. 2. Connect the Rheometer (connector RS232 at the instrument back side) and one of free serial interface (e.g. COM2) of the PC. Here use only the data link (supplied by BROOKFIELD as an accessory). 3. Switch on the PC and the Rheometer.
14. Start measurement at the Rheometer. Measurement points must now be seen as text at the PC display after a short period of time. 15. After completed data transfer of one or several measurements into the selected text file, break the data transfer and end the Terminal Program. If it is necessary to select some other receiver for serial data transfer (not a PC), pin layout of this receiver must be checked before the connection.
VII. Measurements VII.1 Measuring in manual mode To carry out measurements in manual mode you can act in correspondence with the following brief instructions: Measurement control: • • • • Fasten the R/S Rheometer at stand (see Chapter 3). Connect the AC adaptor (see Chapter 3). Connect, if necessary, the printer (see Chapter 3). Fill and mount the standard measuring system (see Chapter 5).
Point to the fact that any substance or solvent do not ingress into measuring bob coupling, measuring drive or electronics. • • • • • Check the presence of the temperature control liquid. Wait for temperature control till the attainment of the desired temperature in the measuring substance. Start a program or a single measurement (see Chapter 6). After ending of the measurement and switching off of the temperature control wait till the cooling/warming of the medium to room temperature.
