ഇലക്ട്രിക്കൽ സ്കീമാറ്റിക് ഡയഗ്രം
The electric circuit of the instrument is composed of a single-chip circuit, a temperature sampling circuit, a heating drive circuit, a stirring circuit, and an uncap circuit.
The electrical schematic diagram is shown in Figure 3.

Usage of the instrument
ഉപയോഗിക്കുന്നതിന് മുമ്പ് തയ്യാറാക്കൽ

1. Please read the operation manual carefully before using the instrument.
2. Read the standard ASTM D93 “Test Methods for Flash Point of Petroleum Products (Pensky-Martens Closed Cup Methods)” carefully to know well the test method, test procedure, and test requirements.
3. Prepare all kinds of test tools and materials as per the requirements of ASTM D93. The instrument should be put in a dark and sheltered place for the operator to observe the flash fire easily.
4. Check the instrument’s working condition to make sure that it is in accordance with the environment and conditions required in the operation manual.
5. Check the outer shell of the instrument to make sure it is in a good ground state.
6. Pour the quantitative sample into the oil cup and then put it in the heating furnace. The stirrer will be moved by a stirring motor via a driving flexible shaft. It should be installed well.

Display interface and keyboard operation method

1. The display interface will be shown as Figure 4 after switching on or pressing the Reset key:
   • At this time, the operator can press ▼ the key to move the cursor and press ▲the key to change the parameters and set states.
   • The set step is divided into A and B.
   • Automatic ignition has an Open and Close.
   • Automatic heating has an Open and Close.
   • The preset range of flash point is 0°C – 400°C.
   • The instrument will automatically store the set parameters after all the parameters have been set up.
2. After switching on or resetting, press the Record key, and the operator can get the interface shown in Figure 5.
   • TC is the modified value. It means the difference between the actual temperature and the measuring temperature.
   • PC is the Parameter value of PID adjustment.
   • IC is the I parameter value of PID adjustment.
   • DC is the D parameter value of PID adjustment

The operator can set the parameters above at this interface.

1. Press the Record key to move the cursor. Then press ▲the key to increase the parameter or press ▼the key to decrease the parameter. The parameter will increase or decrease rapidly if the operator keeps pressing the ▲key or ▼keys.
2. Under general conditions, the three parameters of PC, IC, and DC have been set up when leaving the factory, and do not need to be revised casually.
3. Under the condition of Reset, press the Start key, and the working interface will be shown as Figure 5.
   The Temp. means the location temperature of the temperature sensor. The Power means heating power. The heating power increases as the value grows. The Time means the relative time when working. At this time, the instrument does not really work. Press the Start key again, the instrument starts to go into work condition, and the time value begins to change.

Work pattern of step A

1. Set the step to be A state. Automatic ignition and automatic heating should be on.
2. Press the Start key to make the instrument go into the initial working condition of step A.
3. Press the Start key again to make the instrument go into the actual work condition of step A.
4. Under the condition of step A, the stirring rate is 90(r/min) – 120(r/min), and the heating rate is 5(°C/min) – 6(°C/min).
5. Begin to ignite under the expected flash point 23(±5°C). Ignite once every increase of 1°C and stop stirring when igniting.

Work pattern of step B

1. Set the step to be the B state. Automatic ignition and automatic heating should be on.
2. Press the Start key to make the instrument go into the initial working condition of step B.
3. Press the Start key again to make the instrument go into the actual work condition of step B.
4. Under the condition of step A, the stirring rate is 250(±10r/min), and the heating rate is 1.0(°C/min) – 1.5(°C/min).
5. Others are the same as step A.
   Attention: The operator must use the instrument strictly according to the requirements of ASTM D93.

The automatic ignition is in the off state
After the instrument goes into the actual working state, manually (press ▲a key or ▼key) change the heating power to control the heating rate.

Record the flash point
If the flash fire occurs in the actual working process, immediately press the Record key to record the flash point of this test. The stirring and heating will stop at this time.
