Checking the measuring range (span)
1. Press key (in start screen) to go to the main menu.
2. Select Start-up (1) with or
key and confirm with key.
3. Select Span (1.6) with or key and confirm with key.
The current values for differential pressure, span and maximum differential pressure
(Δp
100
) are displayed.
4. Use a precision regulator to apply a test pressure corresponding to the max. differen -
tial pressure Δp
100
while monitoring the pressure gauge.

When the reading and output signal do not match the indicated Δ p
100
value, readjust
the upper range value (span).
