 Differential pressure indicator has been adjusted at the factory, the differential pressure value 0.5Bar. An adjustment screw on the side of the low pressure on the connection side of the differential pressure indicator, this screw adjustment screw for the pressure value. Clockwise direction (ie screws to the inside to tighten the direction) adjustment screw circle, the pressure difference increases. 
 06Bar; each counterclockwise (ie, the screw out loosen direction) to adjust the nail circle, the pressure difference decreases. 
 06Bar. If the current differential pressure value 0.5Bar To adjust for 0.2Bar counterclockwise adjustment screw 5 turns; if the current differential pressure value 0.2Bar To adjust for 0.5Bar, you need a clockwise adjustment screw 5 ring; this and so on. 


 Indicate the calibration of differential pressure: If you want to calibrated differential pressure indication meter differential pressure value can be removed from the machine, the high-voltage side connection on the pressurization equipment, and pressure gauges, open the terminal box cover to observe the action of the relay (to keep quiet, there was a noise when the relay). To pressurize the high pressure side to the calibration of differential pressure value, such as calibration 0.5Bar When the pressure gauge readings for 0.5Bar, rotate the adjustment screw when the screw position when the relay is a differential pressure value 0.5bar the position to calibrate the other values. 

 Divided into units of time to filter up to 9999 minutes; the sewerage time in seconds as a unit, the maximum time to 99.99 seconds. Power on the machine, use the selector switch into automatic state, the first filter, the filter time timer starts timing, pressure switch is the actual pressure and set pressure to compare, if you set the filter to the, while the pressure difference not arrived, the machine also open the drain valve for cleaning sewage, filtration time to stop counting
