Hi, all. Shamefully, I'm asking if there's a quick key to the various codes at the end of the LED display date as they read out.

For example, "conductivity 1.0322 +" and "Ph 8.2 +" Thus far, I've guessed, but some of them have a * and other symbols. This applies to sensor readings.

A key would be great.

not a silly question!

Answer
This is the output state of the assigned (temperature- , pH- ,etc.)controller.
+ means controller wants to increase the current value, - means the controller wants to decrease.
The temperature control uses different symbols because there are other algorithms:
"*" - wants to cool
"~" - bottom heater (if present) should be active
"|" - tube heater should be active

You can read these things in the manual under 3.2.5 and 3.2.6

Many thanks -- and greatful the symbols turn out to be so logical (e.g. "~" for bottom heater makes sense and it memorable).
