I've been seeing intermittent bad pH readings a couple of times each day. I'll get a log value of -1, those values show up on the graphs too and I've seen them appear when watching the scrolling readings on the LCD. I'm a bit stumped on how to proceed.
I've swapped the EZO pH stamp and the carrier and the issue persists. I tested it on a second bench setup and the issue persists as well. I have two EZO stamps -- COND and pH -- and they're both connected via I2C since I wasn't able to get a connection using serial.
Haven't yet bought a new pH probe, but thinking that may be the next step... Might try to get the serial mode working, but I don't know if that could cause this issue.
Anyone else experience a similar problem?
