Operating Procedures for EFP110 Fully Automatic Closed Flash Point Tester

1Test procedure

1．Cool the bath temperature to below 40 degrees Celsius. If the flash point of the oil sample to be tested is around 40 degrees Celsius, the bath temperature should be lowered to below 25 degrees Celsius;

2．Prepare oil sample: Pour the oil into the engraved line of the sample cup;

3．Place the sample cup into the bath and install the cup lid onto the sample cup, tightening it clockwise;

4．Set experimental preparation parameters, such as tester name, sample number, expected flash point, etc;

5．Click the "Run" button to enter the test interface, and then click the "Start Test" button to start testing the instrument;

6．Automatically stop the test until the flash point is detected or the safe temperature is exceeded.

IIPrecautions

1．When preparing an oil sample, if the flash point value of the oil sample is relatively high, the oil sample will expand at high temperatures, which will cause a high mark on the liquid level of the oil sample at high temperatures, which may penetrate the flash point sensor and ultimately lead to false or no flash point reporting; Therefore, in this situation, when pouring oil, the oil sample can be poured less and the liquid level should be slightly lower than the marking line;

2．When installing the flash point sensor, the exposed part of the flash point sensor should be around 5mm;

3．Before the experiment, it is necessary to check whether the flash point sensor has adhered to the oil sample. The flash point sensor and the bottom of the cup cover should be wiped clean;

4．If there is a false alarm or no alarm for the flash point, in the "Management" ->"System Settings" interface of the software, the threshold for the flash point thermocouple should be between 0.2-0.5, with a default value of 0.4. This value will increase the detection sensitivity and decrease the sensitivity.
