Kh director error:taking to long

[Michael Gray]

Noticed my 6pm test failed. It's been really consistent. Currently at barber shop and log in to see it and noticed the error. Manually started another test. Noticed pH is at 8.17 and staying there. Not dropping anymore

Check for bubbles in the line.

Check for bubbles in the line.

I forgot to respond. I went home noticed no reagent in the line at all. I moved the bottle over and I guess didn't realize it was halfway down the bottle not touching bottom. Pushed line down. Bled the reagent line. And ran it. 3 times. Back to reading 7.6

That would produce an air bubble hehe.

Did you enable the virtual container on the dosing pump? You can set it up so next time
It alarms heh.

Every time I've thought that something's gone wrong with the equipment it's been user error.

 

[Ditto]

Trust me we all think that way lol.

 

[Michael Gray]

Woke up and again same error. But nothing looks eierd except when I log in and look at pH levels it's showing like 10.16ph as it's filling but tank is only 8. What the

 

[Michael Gray]

As it's flushing. It's reading 11.12ph. What the

 

[Michael Gray]

Just flushed the system and it's still locked in on showing 11.12ph??????? Inside cell

Now logging in. It's jumping without doing anything. From 8 to 11.12ph. pH probe broken?

Recalibrate the probe.

 

[Michael Gray]

Recalibrate the probe.

I did. And called Vinny. Seems like something in probe just took a poop.

3 different calibrations. Look at adc then the probe is sitting in 7ph fluid after complete and it's all over

 

[Michael Gray]

Calibrated one last time. Same adc and pH reading after inside the 7ph fluid is weird. Then I'm flushing the cell with pH probe in tank and it's just frozen at 7.

 

[Michael Gray]

Got my new probe from Vinny and installed it. 24 hours of running and running at 7.8. Which is close to my 7.6hanna. At work. At my 6pm run. 8.5. I said no way. I clicked test again while at work. And now 12.3. I'm watching the test. pH reading. And it starts to drop. Then up to 10. Then back down to 7 and drops. Flicks to 10. Now that it's done. Says it's 12.3. I'm sitting and watching my pH reading in kh director go from 3 to 8 and all in between. When I first got the machine it held steady after a test like 4 or 5. And when it filled up it was high 7. Flickering. Again. On a new probe.

The khd is officially getting unplugged.

so i got home at 12:15am and started recalibrating pumps.. testing.. calibrated..probes...calibratin probes again this time in GCC not the app. takes SO LONG.like 15min per solution. i put probe back in 4 solution to test if it reads for and it slowly drops and will go up and drop and slowly settles at 4.1 after like 5 min.... its not quick like id think a regular probe? is this normal?

currently trying to calibrate probe again now thats why im up


now it wont even calibrate.... on GCC. im watching the PH actual value change as ADC changes... its reading 10.0 and ADC is 4... and this is the DANG new probe..

 

[Ditto]

When you put the probe in the solution does it go to 4 and when you put it into the 7 solution does it read 7?

 

[Michael Gray]

Step back from that because i can't even get it to calibrate. On gcc watching it try to find ADC it goes up and down so I watch the pH value go up and down and it won't ever go to 4 and stay to lock.in the.adc. It will.even finish calibrating the pH 4 with it saying 10ph so the adc is high like 49000 or it drops to 4 ADC which locks it down to like 3ph. I watch it skim through ADC for 20 min. It will sometimes go to 4.0 like 45000ish ADC but just goes through it. So I gave up hanged the khd out. Opened it open it up to see if any water got in there and it looks clean. I think it's not the probe and maybe the probe port but it looks clean inside. (yes I cut the warranty tape). Cause at this point I can give a hoot at this point.

Just waking up so I'll be at it again if anyone is on to try to trouble shoot with me

It could also be a bad unit, something happen to the electronics inside that we can not see. I would also get a ticket open on it to GHL so if it is bad they can replace it.

 

[Michael Gray]

its to late. i opened the sticker to look inside to see if it was clean inside that says voids warranty...so would just toss it... gonna try to calibrate again

 

[Michael Gray]

just tried to recalibrate and it goes to ADC 3 4 or 5 which is showing the probe at 10 PH again... theres no way its the new probe that i received... so most likely wasnt even my other probe....

 

[Ditto]

Talk to Vinny before saying it is void but if it not calibrating then we need to talk to support.
