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 110 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.
