I just posted about an issue with our Hach Cl17sc with a sc200 controller but after several frustrating days i finnaly fixed the issue but now we have a new one

Info about our plant: small rural city drinking water plant (package plant), only operate for about 16hours a day. The problem meter in question is used to monitor our finished water's free chlorine. The cell light is operating at 38%, buffer and indicator were replaced on the 1st of July, Tubing was replaced less than a week ago, faulty gasket replaced and cell was cleaned yesterday, software appears to be up to date with Hach website.

But this is the situation.

Yesterday i got off shift after fixing the meter and all was fine with it until the night shift shut the plant down for the night and after that the reading has been going from 0.00 to 8.00+ with every other read cycle, continuing even after the plant was started back up this morning and through to now at the time of posting this. it seems to be dispensing everything appropriately and when provided a grab sample it measures it with relative accuracy and after calibrating it several times i can not for the life of me figure out what it is doing and how to fix it, I've tried turning it off and back on, calibrating, cleaning the cell, priming, and I've got nothing else i can think to do other than have the techs come out and mess with again but they've proven to not be the best at solving these issues let alone quickly.

Any ideas why it would do this and how to fix it? I'm so confused.

Update: Well after leaving the analyzer to do its thing for several hours it is no longer jumping between 0.00 and 8.00+ But it refuses to go below 2.30 despite the water it is analyzing coming back in the 1.10 - 1.40 each time we tested it. And after attempting to calibrate it it refuses to read the standard above 0.00 and the one time it did it came back at 5.68 and it said to slope out of range recalibrate (or something similar) and i have given up on messing with it until i know more or have a concrete solution. If something changes i will update again but for now that is all i have.

Hello my plant (DW) for the past few months has been dealing with one of our cl17sc scanners not working and we are lost as to what to do, we've had our equipment service techs come out several times with no solutions, they replaced the cell which was the initial problem but after that was fixed a day later it wouldnt show any chlorine just reading 0.01 they came back out and changed settings, calibrated the machine but nothing it still wouldnt read any chlorine level, well finnaly they said try replacing the tubing and cleaning the strainer so i just did that after the part came in but still nothing after several prime cycles, it'll read something higher 0.45/0.98 for one cycle then it goes back down to 0.01, cleaned the cell nothing, the bottles are about due to be changed but i see no reason they shouldn't still work if the other machine we have is running fine. Any ideas or help would be greatly appreciated as we can't seem to figure this out.

Im looking at turning an old pc i got for stupid cheap from a buddy into primarily a media server and if it can run it id like to have a minecraft server for me and a few friends off it aswell but thats a secondaryand not that important.

But I've got two problems I've never done this before and and the information online is a bit overwhelming.

But the current specs on the PC

Asus P5K-E motherboard

Intel core 2 quad

4gb of ddr2 ram

RADEON R5 220 graphics

Thermaltake Toughpower 650w power supply

And some random hdd/sata drives i had laying around

Could this do what i need for a simple small media server for all of our movies and such or should i just go another route?

Also I'm not worried about power consumption as ive seen people complain about that with older hardware.
