controller indicates the local atmospheric pressure in the pressure units

Convectron Gauge Analog
Output Signal
Repeat this procedure for Convectron Gauge B.
If the Convectron gauge capability is installed, a voltage output signal
proportional to the common logarithm of the pressure indication is
provided on the rear panel of the Convectron gauge module via a standard
1/8 in. miniature phono jack. See Figure 5-13.
If graphed on loglinear axes, the output voltage is linear with respect to the
log of pressure. The analog output is 1 V per decade of pressure with a
factory adjusted output of 0 V at 1.0 x 10–4 Torr. See Figure 5-14.
Offset adjustments are provided on the top edge of the Convectron gauge
module that allow shifting the voltage corresponding to 1 x 10–4 Torr
between –7 V and +1 V.
