Analog Output
When the analog output is set to provide pressure signal, the voltage level
is proportional to pressure level and it is generated by control unit
elaborating the independent input by the active gauge.

Description
Programmable analog output.
Can be related to : frequency,
power, pump temperature
(linear) or pressure read
by the external gauge.
The setting can be done by:
front panel or serial line
(win.111).
0V = 0Hz, 0W, 0°C
10V = 1010Hz, 150W, 100°C
See following chart for more
details
Analog output proportional to
frequency (linear).
0V = 0Hz
10V = 1010Hz
