is not accurate, to effect experimental results.
4. If you do blank test, open the protective cover, then the oil
sample test should also open the protective cover, keep the test
ambient light consistent.
5. The cup into the cup tray, must ensure that the bottom of the
cup is completely into the tray, ensure light detection is not affected.
6. Each finished experiment cup must be removed from the
cup tray, so as not to affect the experiment positioning.
7. At the end of the experiment, the neutralizing liquid and the
extraction liquid bottle should be placed in the shade to avoid
deterioration.
IX. Troubleshooting
1. Neutralization liquid droplet, slow or little.
①
It maybe liquid bottle cap not tighten, air leakage. Tighten
the cap.
②
Cleaning not enough, neutralization liquid needle blocked.
Solution:
Replace 4.5# needle, adjust the needle angle, the droplet
number detection accuracy.
2. Low acid value oil test results 0.0001mgKOH/g or big error
phenomenon.
