How to Calibrate a Co2 Regulator
- 1). Turn off the Co2 bottle and turn the main regulator knob counterclockwise until you feel no pressure while turning.
- 2). Go to the needle valve underneath the bubble counter and turn it counterclockwise until you can turn no more.
- 3). Return to the Co2 tank and turn the main regulator knob clockwise, opening the tank completely. No bubbles should enter or come through the bubble counter at this point.
- 4). Slowly turn the large knob on the regulator until bubbles are exiting the regulator bubble counter. Work very, very slowly in order to work the bubble count at a reduced rate.
- 5). Turn the large knob approximately one-eighth to one-quarter of a turn clockwise and wait between 30 and 45 seconds.
- 6). Repeat Step 5 until the bubble count is equivalent to what you're looking for. Use the needle valve as a last resort, in order to finely adjust the bubble count.
