ORP Calibration - Core Balance Control
CORE BALANCE CONTROL Chemical Automation Platform | App-Enabled | Full Package With Wi-Fi
Hi, The ORP calibration setting in the app won't go below 550 mV. I press the (-) button and it just stops at 550 mV. The ORP calibration packet I received with the unit is below that 550 mV value. What should I do to calibrate the unit?
