Anyone has the Minolat Booster II sensor? If you do do you know each mark of the calibration dial related to. I thought it's 1/3 stop as the number are 3 marks apart but I found that's it's exactly 0.3 stop so 3 marks is only 0.9 stop. I tried on 2 different meters and the result the same so it's not due to the meter calibration drift. But the Booster may drift so I wonder if anyone has it and can find out what it is?
