KH Director PH Probe won't calibrate

[carjeff87]

I posted this on the ghl website forum see below

I originally had an internal leak so I opened up a 4 day old unit and fixed the pin hole leak in the tubing. The board got damaged so GHL wanted a 50 dollar inspection fee, since I opened the unit up and I figured they would deny my warranty anyways so that's why I opened up the unit. So instead of sending the unit in I ordered a new replacement board, this time I applied a protective conformal coating to protect the board from future saltwater damage. Everything went well for 1 whole day. The next day the Ph Probe lost calibration and read 0 and ever since then It's just a fancy Paper weight all other functions work even the unit says calibration was successful except it reads 0? Anybody have any Idea what else I can do before I throw this unit in the trash and go back to another solution?

When you do the calibration of the probe does the Acd1 or acd2 value change.

Not anymore, it did when I was able to calibrate the probe.

I forgot to reply to your post, no It doesn’t change.

oh probe was fried as well is my guess

Maybe an idiotically question - have you test to disconnect the BNC connection and afterwards connect it again? The second idiotically question - have you test to disconnect the KH director from power and after around 30 sec connect it again?

@carjeff87 did you fix the issue? I am in the same boat.

Nope. Went in storage with all the other gear that isn’t worth a dang.
