External Voltage Control of Current Output

Background

External voltage control of the current output is
accomplished using the MIL-26 connector on
the rear panel. A voltage of 0~10V is used to
control the full scale current of the instrument,
where:

Output current = full scale current × (external
voltage/10)

Connection

When connecting the external voltage source to
the MIL connectors, use shielded or twisted
paired wiring.
