instructions
Proportional bands factors of pH and / or ORP can be programmed between 5 and
300 times the minimum band (x1)
For pH « x1 » represents 0,04pH that is for a factor of 5, a band of 0,2pH
For ORP « x1 » represents 1,6mV that is for a factor of 5, a band of 8mV.
« Factory» values are: x20 for pH and x50 for ORP.
For instance, that means that for a differential value of pH of 0,2, the metering pump
runs at 100% of its time; for a difference of 0,1 pH, it runs at 50% of its time.
The basic operating time of the pumps is 240 seconds or: 4 minutes!

Remark: The proportional band can be modified in a functional range of 0,05pH to
3.00pH!
The factory setting is fixed to 0,8pH!
