FL XX
Digital filter:
Increase the value with Arrow-Up key, decrease the value with Arrow-Down key.
By increasing the XX value the filter effect increases enabling the operator to find out
the average value of unsteady or pulsang pressures. Selectable values are 0 up to 99.
This funcon also acts on display conversion speed, therefore if PEAKs shall be detected,
it is recommended to decrease the filter effect at its minimum.
r XX
Resoluon:
In this step it is possible to set the resoluon used by the instrument to display the
pressure. Selectable values: 1, 2, 5 and 10.
oFFXX
Time of POWER-OFF funcon:
This parameter defines the me in minutes (from 1 to 30) before the AUTO-POWER OFF
acvates in case of constant pressure. The AUTO-POWER OFF me starts working if
the instrument does not detect pressure changes higher than 10% of full scale rate FS.
ZEroO
Only models with absolute pressure range:
With this parameter it is possible to deacvate the ZERO funcon. This is strongly
recommended for absolute pressure range. ZEroO = Off, ZEro1 = On.
bAUdO
Baud rate of the (oponal) RS232C interface:
The transmission speed of RS232 serial output (if provided) can be programmed
4800, 9600 or 19200. We recommend to disable RS232 if it is not used (bAUd0).
6. RS232 communicaon
Communicaon protocol: 8 data bits, 1 stop bit, no parity. Data transmission zyclic every 100 ms.
To read the value displayed on the instrument, send the string
p000cr
