Digital calibration at SX-300 octane tester

Now I am going to tell you how you can perform a digital calibration on SX octane analyzers. So called digital calibration is needed when you have a custom (not regular) type of gasoline that shows a different octane number from what it should be. For this demonstration we are going to use the imitator as a model for a custom type gasoline sample. Let’s assume that we know that the octane number of this sample is 92. Ok. Let’s turn the analyzer on, and switch it to Octane1 mode. We begin our calibration by pushing the [COR] button which is short for “correction”. After that with [SEL] button you choose a needed parameter. In our case it is RON (Research octane number). And we need to make this number smaller. We do it pushing the [S] button until we get the minus “-“ sign here. And after that we start changing the number with the backward arrow until we reach the desired 92 number. To save this correction we push the [COR] button once again. So for this gasoline type we are going to use the corrected Octane1 mode in the future. If we need to cancel the correction, we enter the [COR] mode and with [SEL] button we choose the corrected parameter, with [S] button we make sure that there is “Z” sign over there and with this “Z” sign on we push any of the arrows once. And [COR] to leave the correction mode. The correction is canceled.
