External Voltage Control of Current Output

Background

External voltage control of the current 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 current = full scale current x (external

voltage/10)

For 0~5V:

Output current = full scale current x (external

voltage/5)

Connection

When connecting the external voltage source to

the connectors, use shielded or twisted paired

wiring.
