Below this are the instructions, to complete the calibration, follow these steps and press OK after waiting 2+ minutes.
There is no limit how long it takes to complete a step, you can leave the probe in the solution for 20 minutes if you like, and
press OK, just be sure to leave it in the buffer solution for more than 2 minutes.
When calibration is complete, press OK and you'll see a screen verifying this.
If you selected 2 point or more you'll be taken to step 2 or 3 after pressing OK. The screen will confirm the calibration
solution you selected, at the beginning. Simply repeat the above steps, using the other solutions, until it tells you the
calibration is complete.
For the 2 Point calibration, you will need both the Mid point and the Low point solutions, which you selected at the
beginning.
For the 3 Point calibration, you will need all 3 solutions, the Mid point, the Low point and the High point solutions, you
selected at the beginning
*Remember: always rinse your glass container with RO or distilled water before adding the solution, and only pour
out enough to just cover the probe tip, and swirl the probe around to ensure full contact with the solution and to
get rid of any trapped air.
