Conductivity failed

[Crackem]

I keep getting a calibration failed message and it goes back to default.
Can someone please give me a step by step and don't say read the guide cause I did. I even printed it. Unofficial and official. I also could not get the temp working in the pm2 so for now it's in the base. I bought a conductivity solution packet which I tried using the 1st time it's by Milwaukee and says 1413 us/cm standard conductivity solution.
M10031. This did not work it failed every time.
Than I tried a 53.0 ms pinpoint salinity monitor calibration fluid that I bought for my refractometer which seemed to work, but I'm not getting a reading still. Any help would be greatly appreciated. Also I installed the probe in my sump and not sure what color it was since I had a friend helping me. If I have to recalibrate I don't want to pull out the wrong probe.

If I go to module menu and module name I have a pm2_5

I also keep getting emails and text even tho my temp is with normal range.
This is my email alarm program
EmailAlm_15
Set ON
If Temp > 82.0 Then ON
If Temp < 76.5 Then ON

Change to Set OFF

Thx Russ now I am going to attempt to calibrate temp and conductivity on pm2

 

[Crackem]

I didn't get a fail message this time and i got a reading of about 31.0 but now I can't access the apex all of sudden and sorry if I sounded ****ed but this thing is frustrating sometimes.

You need to have this to Set OFF not Set ON, you want it off unless one of your lines turn the Email Alarm ON.

As far as the temp is conserned, just make it what ever it read plugged into the apex base unit.

Example:

If it read 76.0 on the base unit and it now reads 79.0 on the PM2 just calibrate the temp sensor to what it read on the base unit of 76.0

 

[Crackem]

For some reason when I go to modules it shows I have a pm2_5
And a pm2_6. Also the first time I tried to hook temp probe to pm2 it didn't read a temp at all.

I finally have conductivity probe calibrated when I take it out of my tank or sump and I put it in 53.0 solution I get a reading around 34. When its in my tank it reads .5-.9??? I don't know what else to do. I'm going to fill a cup of water from my tank and see what it reads.

 

[Crackem]

Ok It works when I tested it in a cup but it does not work in the sump or in the tank.

Shut down everything electrical in the tank setup (except for the Apex of course). See if the reading is normal. If so, turn things on one at a time while you observe the conductivity reading. The goal is to see if anything is causing interference or is causing stray electricity in the tank/sump,

 

[Crackem]

You are good Russ Thank You it's my lighting! I'll have to do some tidying up behind the tank ASAP thx again. I do have another question about how to test my float switch emails but I'm trying to keep my threads separate in case anyone else has similar problems. I'll bump that thread later thx

I isolated the interference to my power compacts and metal halides so today I separated all the wires from my lighting from my probes. Ballast wires are now on the opposite side of the tank from probe wires. Conductivity readings still drop from 33 down to 11 or lower. So I went out and bought a ground probe and still no luck. Whenever I turn power compacts on or halides I get a huge drop. I'm out of ideas for now.

 

[Crackem]

I'd rather not send my probe and module back to Neptune because it does work when I put the probe in a cup of tank water or calibration fluid. Is there anything like insulation that I can put on my ballast wires to stop them from interfering with my conductivity probe? Would duct tape or electrical tape do anything?

 

[RussM]

What happens if the lighting is plugged directly into the wall instead of the EnergyBar?

 

[Crackem]

Ill test that asap

It drops from 30.0 to 11.0:headwalls:

 

[Crackem]

Anyone have any ideas or should I send it back to Neptune for testing? As far as I know my other probes are working fine even tho orp is around 250-280, it might be affected but it doesn't drop like conductivity.

 

[RussM]

Call or email Neptune and ask, but it sounds to me like EMI from the ballasts.
