BAUD
[Factory default = 19,200]
This sets the baud rate for the RS485 and the RS232 serial
communications. The baud rate can be set to various values
through the serial interface or via the front panel soft-keys. The
parity can only be changed through the serial interface command
set. When this occurs, the current setting will be shown in the list
of choices and can be re-selected if changed.
RS485 TYPE
[Factory default = 2 WIRE]
Selects 2-wire or 4-wire configuration for RS485 interface.
ANALOG TYPE
[Factory default = LOG 1-8 ]
Select one of the following analog output types based on your
system requirements (See section 7.0 for details).
a) LOG 1-8. This selection provides a 1 to 8 V (dc) log-linear
analog output with 1 V/decade.
b) LOG 0-7. This selection provides a 0 to 7 V (dc) log-linear
analog output with 1 V/decade.
c) NONLIN 6V. This selection provides a non-linear (S-Curve)
analog output from 0.3751 to 5.6593 V (dc).
d) NONLIN 9V. This selection provides a non-linear (S-Curve)
analog output from 0 to 9 V (dc).
e) LINEAR. This selection provides a 0 to 10 V (dc) linear
analog output with a useful range over 3 decades.
SET LINEAR
[Factory default = 0.01 VOLTS to 10 VOLTS
corresponding to 1
mTORR to 1
TORR]
If you have selected LINEAR in the ANALOG TYPE menu
above, then configure the linear analog output scaling using the
following parameters in the SET LINEAR menu. (See section 7.9
for more details).
a) Set the minimum pressure
b) Set the minimum voltage corresponding to the minimum
pressure
