(open thread for anyone using Simpool pH or similar Seko or any brand small acid injection / sensor systems)
am always having fun in calibrating the Simpool pH, per the user directions on pg 15 of the manual.
apart from the dearth of english majors at the factory, does anything in the above implies that the "knob" needs to be in a startup pH dial value or it does not matter, ie. for example it could be currently in 6.5 and the directions for calibration are the same ?9.2 pH Regulation
. Dip the pH electrode into a tap water glass
. Dip the electrode into the pH 7.3 buffer solution and share for a few seconds
. Leave electrode into buffer solution, place on plane surface and don't touch cable or electrode
* Rotate a little bit clockwise to the right hand side knob
-- If the right hand side led is green rotare clockwise the know (yes, know, not knob) until the led will become orange colour.
-- If the right had side led is red rotate anticlockwise the know (yes, know, not knob) until the led will became (not becomes) orange colour.
. Assembly the front panel of the pump (-end of directions-)
I've tested this condition and usually the probe would immediately pump small quantity of acid when placed into the tap water for a second and it stops when placed into the buffer solution. It's reaction to the dip (tap) and dip (buffer) depends on start value but the directions are silent as to that aspect.
If I set the dial before the first dip (tap water) into 7.3 it may start to blink green or it may be a solid green. At that point moving clockwise always results in a solid red, unlike the directions which ask for orange colour.
Unit still works fine, I keep dial to a value that maintains 7.4-7.5 despite having fun with the italenglish directions.
