Display elements in menu mode: If you press the Menu (F3) key, a menu will appear in the display which allows you to enter settings.
Menu header: shows the name of the submenu and the currently selected menu line of the total number of menu lines (for example, 2/5: you are in the second of five lines). Set date There are three different menu lines , and : Submenu line: “. . .“ this line indicates that a submenu is called up with OK (F1). “. . . :“ indicates that it is a selection menu. If you press OK (F1) on a selection line in this selection menu, this selection will be confirmed and you will exit the menu.
MENU (F3) UP/DOWN (F2) to "General" OK (F1) Enter the calorific value in the format xxxxx (default: 26460) OK (F1) BACK (F3) Calibration values Once you have calibrated the appliance, you will need to enter the calculated C-values (calibration values) of all the decomposition vessels used.
MENU (F3) UP/DOWN (F2) to "Unit" OK (F1) UP/DOWN (F2) select the desired unit (default: J/g) OK (F1) BACK (F3) Time control Calorimeter C 200 performs the measurement automatically according to a set period of time and calculates the provisional result. The measuring time is set at 14 minutes. Measuring procedure Before using the calorimeter for the first time you must fill the outer vessel with tap water. You can choose between four measuring procedures: 4.
4.8 Switching off the system 4.10 Oxygen station C 248 Standby mode The C 200 does not have an integrated oxygen filling point for the decomposition vessel. You can use oxygen station C 248 for filling. The C 248 oxygen station must be set up at least 1.5 m far away from the calorimeter. For information on how to operate and connect the oxygen station, please see the accompanying operating instructions. In order to switch off the calorimeter system, the start screen must be displayed. Press OFF (F1).
5 Calorimetric measurements 5.1 Determining the calorific value Combustion is carried out in a calorimeter under specific conditions. The decomposition vessel is filled with a weighed fuel sample, the fuel sample is ignited and the temperature increase in the calorimeter system measured.
Note: in all the automatic calculations an extra 100 J have already been included for the electric ignition energy. This value cannot be set. Materials which are diffi cult to ignite or combust are combusted together with a burning aid. The burning aid is first weighed and then put into the crucible with the sample. The additional heat quantity can be determined from the weight of the burning aid and its known specific calorific value. You must correct the test result by this heat quantity.
5.4 Calibration The calorimeter system must be calibrated before accurate measurements are possible. This is done by combusting tablets made of certified benzoic acid (see Accessories) with a known calorific value. The heat quantity required to raise the temperature of the calorimeter system by one Kelvin is used to determine the heat capacity of the socalled "C-value" of the system. For this calculation the formula (1) (see section 5.
6.2 Preparing the decomposition vessel Prepare the decomposition vessel as follows: Cover Union nut Handle Cotton thread Attach a cotton thread to the centre of the ignition wire using a loop. Weigh out the substance directly into the crucible with an accuracy of 0.1 mg. Note the weight or enter directly into the calorimeter. (See section 6.3 "Preparing the measurement"). Insert the crucible into the crucible holder.
Attaching the ignition adaptor Detaching the ignition adaptor 6.3 Preparing the measurement The calorimeter is in ”waiting” mode. 1. 2. Selecting MEASUREMENT (F2) will take you to the "Prepare measurement" menu. Place the decomposition vessel into the inner vessel of calorimeter C 200. The decomposition vessel must be placed between the three locating bolts. Enter the noted weighted sample in the marked "Einwaage" (weighted sample) field with an accuracy of 0.0001 g using the keyboard.
QEXTERNAL2 Correction value for the heat energy from other burning aids e. g. combustible crucible). The default value is 0. TESTNO For each measurement the software automatically assigns a number in the form of yymmddnn, with jj representing the year, mm the month, dd the day and nn a consecutive number. You can also assign your own numbers to the measurements. Example: TestNo = 0509150 represents the first measurement on 15 September 2005 Press OK (F1) to apply your entries.
a) The measurement process is fully automatic for automatic measuring procedures (isoperibol, dynamic and time-controlled, see section 4.6). The result will appear once the measuring process is complete. After the measurement open the cover to automatically empty the inner vessel. Remove the decomposition vessel and the ignition adaptor. To release tension in the decomposition vessel use venting button under a fume hood or venting station C 5030 available in our accessories range.
The combustion residue in the crucible, e.g. soot or ashes, should also be wiped away with an absorbent non-fibrous cloth. 6.6 Errors in the measuring procedure Errors in the measuring procedure are shown in the alarm line of the display and remain there until they are appropriately acknowledged by the user. Message: Cover open! Cause: Sample not combusted. (Cotton thread had no contact to sample) User action: Open cover and remove decomposition vessel.
Message: Fill time exceeded Cause: Start temperature of inner vessel is not in range 22 ± 3 °C. User action: Open cover to cancel measurement, or press CONTINUE (F1) to continue the measurement anyway. Note: A measuring result obtained in this way does not correspond to the standard conditions. Cause: No water in tank. User action: Check the fill level in the tank and top up with water if necessary. Press CONTINUE (F1) to repeat the filling process and continue the measurement.
