3 D oes the LED on the electronics module light briefly?
Y
es: existing pressure was accepted as position adjustment
N o: Existing pressure for position adjustment was not accepted,
note the adjustment limits
Set lower pressure value:
1 R equested pressure for lower pressure value (EMPTY PRES-
SURE) is on the instrument
2 P ush "-" key at least for 3 s
3 D oes the LED on the electronics module light briefly?
Y es: Existing pressure was saved as lower pressure value
(EMPTY PRESSURE) and assigned to the lower level value
(EMPTY CALIB.)
N o: Existing pressure was not saved as lower pressure value
(EMPTY PRESSURE). T ake note of the adjustment limits
Set upper pressure value:
1 R
equested pressure for upper pressure value (FULL PRESSURE)
is acting on the instrument
2 P
ush "+" key at least for 3 s
3 D oes the LED on the electronics module light briefly?
Y es: Existing pressure was saved as upper pressure value (FULL
PRESSURE)
and assigned to the upper level value (FULL CALIB.)
N o: Existing pressure was not saved as upper pressure value
(FULL PRESSURE). N ote the adjustment limits.
I f no local indication is connected, the following functions will be
possible via the three keys on the electronics module or outside on the
instrument:
l P osition adjustment (zero point correction)
l S
et the max. pressure value and assign it to the max. flow value
l I nstrument reset, see chart in chapter "Operating elements"
Information:
T
he adjustment must be unlocked, see chapter "Lock/Unlock adjust-
ment".
B y default, the instrument is set to mode Pressure. The mode can be
changed via the parameter "Measuring Mode", see chapter "Select
language and measuring mode".
T he "-" key is without function
T he existing pressure must be within the nominal pressure limits of the
sensor, see specifications on the "Type label".
S ee also "Quick setup menu" in chapter "Flow measurement".
Carry out position adjustment:
1 P ressure on the instrument
