How do you use the Cal Tool?
 
All you need is a LP hose with a standard Scuba Quick-Connect on your calibration gas tank, and the tool itself.
 
(Calibration is easiest while the unit is laying down, but can be done standing up if preferred.)
 

*** Be sure to purge your whip before attaching to the Cal tool -       ***
*** To prevent dust, dirt, or water from entering the flow restrictor. ***
 

- With the scrubber cannister removed, Place the Cal tool into the CK head

- The Cal tool will slide into the sensor mounting area
        (The depression/cut-out on the rear area of the internal part of the head)




- With the cal gas on, hold the unit in place for at least 30 Seconds, or until the readings stabilize.
        (This allows the cal gas to displace the ambient air from around the sensors)

- While keeping the Cal tool in place, and the gas flowing, calibrate your computer/PPO2 monitor(s)

- Remove the Cal tool (Don't forget to shut off the gas!!)

- Re-attach your scrubber cannister, perform your standard pre-dive checks, and have fun!

Helpful tips:

While learning to use the Calibration plug, and ideally on every calibration, pre-calculate your expected mA reading for your particular Calibration Gas. This will help ensure you're properly flushing the sensors fully.

Don't be afraid to flush for a longer period of time if you have any doubt that the sensors have been fully flushed - The built in precision flow restrictor will use far less gas than the traditional calibration method.

Be sure to set your computer to 100% O2 as the calibration gas before you start.
 
** Keep your calibration plug Clean! Remember, you are using this with oxygen ** 
       To reduce the risk to people and property, store the plug appropriately.
           Avoid Contact with Oils and other Non-O2 Compatible materials
