Analog Output
The XGC-320 provides either a non-linear, log-linear or a 0-10
V (dc) linear analog output signal. These analog output signals
are also compatible with various Granville-Phillips
®
Mini-Con-
vectron
®
modules as well as Convectron® gauge controller se-
ries 375, 475 and the original 1/4 DN 275 Analog Convectron
Gauge Controllers. Please read this section in its entirety to de-
termine which one of the five analog output types to select from.
LOG 1-8; Log-Linear Analog Output
The LOG 1-8 setting selected from the ANALOG TYPE menu
produces a log-linear analog output signal of 1 to 8 V (dc) for
1.0E-4 to 1000 Torr of N
2
. This output, shown below, is a 1 Volt
per decade signal that may be easier to use for data logging /
control than the non-linear analog output.
