Installation Notes when using high voltage for relays (115VAC…250VAC)! The supply cable and control cable for relays should be separate if high voltage (115…250VAC) is used in relay contacts. Both of the cables have their own cable entry. Electrical connection diagram The settings are done according to the instructions below:...
Zero point adjustment Note! Supply voltage must be connected one hour before the 0-point adjustment is carried out. 1) Disconnect both tubes from the pressure inlets + and – 2) Push both arrow buttons or select “Zero” from the menu green led turns off and “Zero”...

High point adjustment (span) Note! Supply voltage should be connected one hour before the span point adjustment is carried out. Note! Span point must not be adjusted without input pressure. If the span point is adjusted with 0 Pa or close to 0 Pa input pressure the device may lose its accuracy and will not give out correct readings.
