does anyone have a video of a IV test being preformed?

I cant seem to get my IV testing properly. ive narrowed it down to either a reagent problem, or a pill stirrer problem. im not sure how the pill is supposed to turn, mine turns real slow, im not sure what "right" looks like. does anyone have a video i could see of what a proper test looks like? i keep getting same error, unable to achieve terminal ph. i know there is no air bubbles, and i know the ph probe is calibrated correctly. it tells me the correct 8.3ph. i even bought a second bottle of reagent and im still having same problem. so i think its the pill maybe?

The test last about 30 minutes. All but the first 10 minutes is actual alkalinity test after the initial drain and fills and the pH and salinity readings.

I was able catch mine in the middle of the test. I did not get the initial drain. The video starts during the inital fill and runs until the actual alkalinity testing starts. It is about 9 minutes. The set of the test is the same as it is in the end of the video until the actual testing is over and then it does a drain and fill at the end. Here is a link to to the video on youtube

. Not sure how helpful it will be. Your water levels in the beaker will be lower since mine has a temp sensor and a suction cup in the beaker taking up some room.
