4.Feature Advantage:
Leading Intelligent Pump Controller features: Parameter Calibration by single button pressing

1.what is Parameter Calibration?
pump manufacturer, pump users etc all know that during the practical operation, there are two major pump running parameters: voltage & ampere, Leading intelligent pump controller can memorize these two major running parameters during the pump operation and protect the pump reliably according to these two major parameters;

Traditional pump controller can not memorize pump running parameters, so it can not protect the pump reliably.

2.how to do Parameter Calibration? ( two easy simple steps)
Step 1: once the pump and Leading pump controller installation completed, run the pump under manual state, check the whole pump system work normal including the voltage, ampere and pump running state
Step 2: press STORE button, Leading pump controller will memorize all the running parameters of pump and protect the pump according the memorized running parameters

3.The purpose of Parameter Calibration
The main purpose of Parameter Calibration is to give more reliable protection against pump and motor, additionally, all the running parameters can be adjusted according to the pump supplier/users special technical request, so it can give the pump supplier/user more customized application

4.Basic Parameter Calibration item list

Because Leading pump controller adopts microchip processing technology, we can add parameter item according to pump supplier/user customized technical request
