Connect another port of neutralizing liquid (ethanol-KOH) to the interface affixed with a neutral label with a hose;... - Page 8 If there is no sample cup on the sample tray, the instrument enters the following interface: Open the front cover of the instrument and place it in the sample cup (placed in the second cup position). After the sample cup is detected, the instrument starts to extract the extract.
- Page 9 When there is 20 drops, the instrument enters the main interface： Click the time shown on the upper right corner, the instrument enters the following interface and time can reset.
- Page 10 Input the date and time in turn and click the “OK” button，time can reset successfully. Note: Stirring should be placed in the cup for calibration and sample testing. Instrument Calibration If the instrument is used in the first time or the neutralization is being changed , this step is necessary.
- Page 11 According the prompt, inject 20ml BTB aqueous solution accurately in a sample cup (see details in the chapter 3 BTB aqueous solution) and put the cup in the sample tray. Click the “Start” button and a blank titration is beginning. The instrument enters the following interface: When the blank titration is finished, if a re-calibration is in progress, the instrument enters the following interface:...
- Page 12 If verification is in progress, the instrument enters the following interface: Input the volume of the standard acid solution; inject corresponding 0.15mol/L standard acid solution with micro injector (see details in the chapter 3 “Standard acid solution”) in the cup. Click the “Start” button, the neutralization is in progress, the instrument enters the following interface:...
- Page 13 When the neutralization is finished, if a re-calibration is in progress, the instruments update the calibration value and enter the main calibration interface. If verification is in progress the instrument enters the following interface: Click the “Print” button to print the result of verification or go back the main calibration interface.
- Page 14 If there is no enough extract, the instrument warns like the following interface: Add enough extract and press “OK”, after the self-inspected the instrument enters the following interface:...
- Page 15 It should be noted that the extract is subjected to blank titration after the addition of the extract. The specific steps are to put a clean sample cup into the sample tray. Click the “Blank” button to start blank titration of the extract. The instrument enters the following interface: Looking for the sample cup, after this progress the interface will prompt to change the cup, the interface is as following:...
- Page 16 Replace the sample cup with a clean sample cup. Click OK to start extracting 20ml of extract. Then blank titration of the extract is in progress, the interface is as following:...
- Page 17 The number of blank titration drops is automatically saved after the titration is completed. The extract should be blank calibrated in the following cases: replace the extract; Replace the neutralizing solution. Then the instrument enters the following interface: Input the oil density, click the “Turn” button and put cups in turn, click the “Start” button and the instrument enters the following interface:...
