I followed step 19 of this thread when I calibrated my pH probe. I should also note that you should be using a 7 and 10 fluids. I was helping someone the other day and they had a 4 and 7 reference solution.... which will make it a little off.
Firmware updating should be done via the GCC windows software. I would do that before calibrating probes and whatnot. While in there, you can also connect it to myGHL, your home wifi, etc. Oh! When updating firmware, your powerbar is up to date already!
Overall, I followed this thread when I setup my GHL system and followed the same steps in the order Ditto did.
Good luck and you have got this
Thanks a bunch! I will look back here to find Ditto’s notes on step 19. I just checked the 2 calibration solutions....you were right: it came with a 4.0 solution in a reddish color and a 7.0 solution in a greenish color. I wonder why they didn’t include the 10.0 solution.
Any 10.0 sample will work, usually your LFS etc should carry the Miluwakee packets.
