External Voltage Control of Voltage Output
Background External voltage control of the voltage output is
accomplished using the analog control
connector on the rear panel. There are two
external voltage control ranges, 0~5V and
0~10V, depending on the F-97 configuration.
See page 108 for details.
For 0~10V:
Output voltage = full scale voltage x (external
voltage/10)
For 0~5V:
Output voltage = full scale voltage x (external
voltage/5)
Connection When connecting the external voltage source to
the analog connector, use shielded or twisted
paired wiring.
