Operation Procedure — Open Cup Flash Point Tester
1. Pre-test Preparation
- Place the instrument on a stable workbench without obvious airflow.
- Clean the test cup thoroughly with solvent and dry completely; no residual oil or impurities left.
- Connect AC 220V power supply. Link liquefied gas source and check for gas leakage.
- Pour sample into the test cup up to the marked level, avoid bubbles and overflow.
- Put the test cup into the heating chamber steadily.
2. Parameter Setting
- Switch on the instrument, the large LCD screen lights up.
- Select test standard GB267-88 / GB3536-83.
- Input expected flash point, sample number and operator information.
- Confirm printer status if printed report is required.
3. Start Automatic Test
- Press Start button; the test arm descends automatically.
- The instrument starts heating according to standard temperature rise curve.
- When approaching the expected flash point, the igniter automatically ignites and performs flame scanning.
- Once flash vapor ignition is detected, the tester automatically locks the flash point value, stops heating, extinguishes flame and cuts off gas source.
- The result can be displayed on screen and printed automatically.
4. Post-test Operations
- Wait until the heating chamber cools down. Take out the test cup carefully.
- Clean test cup, temperature sensor and ignition assembly.
- Close gas cylinder valve first, then shut down instrument power.
- Store the instrument in dry and ventilated environment.
