ANALOG CONTROL
163
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. 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 analog connector, use shielded or twisted
paired wiring.
