Safety instructions Read the operating instructions in full before starting up and follow the safety instructions. Keep the operating instructions in a place where they can be accessed by everyone. Ensure that only trained staff work with the appliance. The calorimeter C1 may only be used for the determination of calorific value of solid and liquid materials according to national and international standards (eg DIN 51900, BS 1016 T5, ISO 1928, ASTM 5468, ASTM 5865 and ASTM 4809).
We recommend that you send the C1 calorimeter system to our factory for inspection, and if necessary, repair after 1000 tests or after one year or sooner depending on use. For the purposes of these operating instructions a technical expert is someone 1. who guarantees to conduct the tests properly on the basis of his training, knowledge and experience gained through practical work, 2. who is suffi ciently reliable, 3. who is not subject to any instructions in terms of the test activity, 4.
Transportation, Storage Transport and Storage conditions The system must be protected against mechanical impact, vibrations, dust deposits and corrosive ambient air during transportation and storage. It is also important to ensure that the relative humidity does not exceed 80%. The appliance must be completely emptied before storing and transportation. In case of repair the device has to be cleaned and free from any materials which may constitute a health hazard.

System start Switching on the system (in the open state) After switching on the calorimeter, first the initial screen with the IKA ® logo, the calorimeter-type and the software and firmware version. INFO: Upon initial system start, the menu language must be selected.
Pressure test A pressure test must be performed after a decomposition vessel has reached or exceeded the recommended number of ignition cycles. Once the pressure test has been performed a release code can be entered to enable the unit to be used for further measurements. The warning message will then disappear. The enable code can be in the following screen, by pressing the „Next button“ to be entered. INFO: Using the unit may be further worked.
Heating detected If the use of heating selected C1.20 (accessories) in the Setting menu, but this is not recognized, the following user information is displayed. NOTE: Check that the heater is correctly connected and turned on.. Factory settings As delivered, the C1 calorimeter system is configured as follows: Settings: • • • • • • Menu: Color palette: Key tones: Date device: Time device: Units: animated white on 01.01.
Corrections Fuel sample Heat quantity from: External energy Burning aid Igniter Formation of Formation of sulphuric acid nitric acid As determined by the system, during a combustion experiment, not only is heat generated from the combustion of the sample, but heat also occurs in the form of extraneous energy. This may fl uctuate considerably in proportion to the heat energy of the fuel sample.
• Under the conditions that prevail during calorimetric measurements, sulfur and nitrogen un-dergo combustion and form SO2, SO3 and NOX. Sulfuric and nitric acid arise in combination with the water resulting form combustion. Heat of solution is also generated. This heat of solution is taken into consideration in calculating the gross calorific value.

Input window NEW MEASUREMENT Select and confirm the menu item „Sample weight“. Enter the sample weight with numeric keypad and confirm. INFO: A distinction is made between the use and non disposable cup. Use of disposable crucible can be selected in Settings " Accessories. INFO: For automatic input of the weight may be a connected scale can be used INFO: The inputted weight values are checked for permissibility.
To increase the service life of wearing parts (O-rings, seals, etc.) it is advisable to always work with a water template. Generally, the test sample must be selected so that the temperature elevation during the measurement is below 10 K and the temperature increase of the calibration comes close (max. energy input: 40.000 J). Such exposure may damage the calorimeter. To determine the potential energy initially very small sample weights (approx. 0.2g) must be chosen when working with unknown substances.
Measurement procedure During a measurement, different phases are passed through. These phases are described below • Phase 1: Filling the calorimeter with water NOTE: After switching on the calorimeter C1 or after a break of 2 hours during the filling of the calorimeter C1 is still carried out an intermediate emptying (H2O - purge). Once the water sensor detects water, the stirrer is switched on. After a short waiting period begins phase 2.
• Phase 3: Filling with oxygen • Phase 4: Stabilizing the temperature and preliminary • Phase 5: The system ignites and thereby starts the main test INFO: An ongoing measurement can be stopped by selecting „Cancel“ at any stage • Phase 6: Post test • Phase 7: Venting, result is displayed • Phase 8: Cooling (if option under the main menu " Basic Settings " cooling is enabled) and water emptying NOTE: With the „cooling“ option, the energy is absorbed (by the combustion in the calorimeter entered).
• Result Display Phase 9: The system is completely emptied, and can be opened. The inner vessel can be taken down. Through a visual check is necessary to ensure that the sample in the crucible was combusted completely. Cleaning the inner vessel After each combustion are all parts of the inner vessel that come in contact with the combustion products to clean condensate. It is sufficient to parts with an absorbent, lint-free cloth to wipe off.
Using a scale About Settings " accessories can be selected using a scale. If this option is selected, the displayed on the scale weight is automatically transmitted to the selected weight input field. Depending on type of balance this function may need to be be activated on the scale or the Transfer button must be pressed. This applies both to the initial sample weight of the sample and the weight of the disposable crucible.
Cancel a measurement An ongoing measurement can be canceld at any time. After ignition, the system waits for 1 minute with the emptying, as otherwise there is a risk that the sample is not completely burned. After confirm the cancellation, the system automatically emptied and bring it to a safe state. The calorimeter can be opened and you can return to the main menu.
System test Functional testing of the system Use for the system test one or two benzoic acid tablets. Alternatively, however, for example, an appropriate amount of sugar or an alternative fuel to be used. The system test is used to test the functionality of the overall system. For this purpose all switching operations are carried out, which take place in a normal measurement. If the system test performed without error, the functionality is guaranteed.

E02 COMMUNICATION If no internal communication between the software and firmware are prepared COMMUNICATION ALARM appears.. E03 DRIFT ALARM Drift Alarm In preliminary experiment or or post-experiment the temperature drift criterion is not met. Check the stirring function. E04 MINTEMPDIFF If 30 seconds is no temperature increase of 0.5 ° C takes place after ignition, the alarm is displayed.
E06 EMPTYWATER Occurs when the lower water sensor during the emptying of system after 60 seconds still detects water. Possible causes for this problem are: • the drain hose for sucking the air is in the water. Check the hose laying on the cooler (see page 8). • the pump is defective. Switch the device off and back on and then run a system test. Disconnect the return flow line and let the water drain into a lower lying container..
