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. In this
case go to menu and select “Span” and then “Reset”. This resets the span adjustment.
To adjust the span you need an accurate reference meter.
Follow these steps to correctly adjust the span
1. Set the zero point *
2. Connect the input pressure
3. From the menu select “Span” and then “Adjust”
4. Adjust the display or 0…10V value to match the reference meter’s value using the arrow buttons and
confirm by pressing OK
*see section “Zero point adjustment”
