I can not find anywhere the steps on how to calibrate my probes.
does anyone have this info?
do i just stick it in the bottle or i use those rubber covers filled with fluid to calibrate?Yes, you have to enter the ph values of the calibration fluids you are going to use.
For freshwater you would use 4 and 7 because the measured value is in this range.
Salt water is somewhere at 8, so you use pH7 and 9 for calibration.
-> the used fluids depend on the value you want to measure, that's why you can change the calibration values
a) I am here quite lazy, I just dip the probe in the calibration fluid bottle, it works
but: it is possible that you pollute the fluid a bit and the next calibration is maybe not as accurate as you wish
-> the professional way is to use an extra container
b) no
I have the redox working. And the ph. But if you read the next step the oxygen sensor thats what im stuck onAre you sure your on a redox port? Below are the steps I had to calibrate mine when was it asking you for the room air?
Redox Probe Calibration: (Steps I took to do it)
From the P4
- Press Any key on the P4, and use the arrow down button and highlight Sensor Setting and press the check mark
- Using the Arrow Key on the P4 highlight the Probe you wish to Calibrate and press the check mark mine was Redox 1
- Using the arrow keys scroll down the list and highlight Calibration and press the check mark
- The display updates on the P4 and is now asking you for to set the calibration Tolerance make sure it is <1> mine was one to begin with and press the check mark
- The display updates on the P4 and is now asking you for the first Tolerance level, I set mine to 220.00 using and press the check mark (it defaulted to this)(To adjust the value use the arrow keys to move left and right and up and down to change the value)
- Insert Null Plug
- Beep Sound
- This display updates on the P4 and is now asking you for the asking you to put the probe now in the 220.00 solution and press the check mark
- Beep Sound
- This display updates on the P4 and is now asking you Save now press the left arrow key to highlight Yes (Box will show around it) and press the check mark
That is an excellent feature!Yes, you have to enter the ph values of the calibration fluids you are going to use.

You have the RESOURCE guide downloaded right? Page 56 is what you need to read for PH Probe calibration. It's pretty cut and dry. The rest of the probes are in that section too.The instructions for this a comically vague:
pH calibration:
Step 1: Connect the pH sensor
Step 2: Set the calibration tolerance
...wut. Set the tolerance? Where!? Digging around forums helps narrow it down, but the fact this thread is from 2017 doesn't exactly inspire confidence. The Programming Guide should have been updated by now and the Manual should have mentioned the Programming Guide. That way people will actually know where to look for the vague calibration instructions.
