Voltage Programming
Maximum time required for output to settle within 1% of its total
excursion (for resistive load). Excludes command processing time.
1V to 6V: 10ms, no load and full load

KEYBOARD & ROTARY CONTROL
All functions, including the selection and set-up of the remote control interfaces, can be set from
the keyboard. The rotary jog control can be used to adjust output voltage and current settings in
a quasi-analogue mode.
