Pushbutton
enable/disable
10 --- --- Select 0 = None
LA = All disabled
LO = All disabled except
zero
LS = All disabled except
zero and full scale
L = Write protect; HART
operation disabled
6.2.8
Characteristic, DP
only
11 --- --- Select lin = linear
srlin = square root (linear
to switch point)
sroff = square root
(switched off up to switch
point)
6.2.9
Set square root
switch point
12 Increase Decrease --- Parameter range 5 to 15%
of flow
6.2.9
Measured value
display
13 --- --- Select Unit of pressure (input
value) or output current in
either mA or 0-100%
6.2.10
Unit of pressure 14 --- --- Select See Figure 6-3 for
engineering units
6.2.11
Notes:
1. Press the M pushbutton to change the mode.
2. IMPORTANT: Absolute pressure transmitters - the zero is established in a vacuum! A zero adjustment to a ventilated absolute
transmitter will cause an error!
3. Press both pushbuttons simultaneously.
DP = differential pressure
