Isolated External Voltage Control of Voltage Output
Background Voltage control of the voltage output uses the
isolated voltage option (PSU-ISO-V). A voltage
of 0~5V or 0~10V is used to control the full
scale voltage of the instrument, where:
For 0~5V: Output voltage = full scale voltage ×
(external voltage/5)
For 0~10V: Output voltage = full scale voltage ×
(external voltage/10)
Connection When connecting the external voltage source to
the isolated voltage option, use shielded or
twisted paired wiring.
