ALARM OUTPUT
Isolated rear-panel open-collector output signal. User can select output to be activated for either
OVP, OCP, Overtemperature or Sense miswiring, or for any of those four faults.
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.
INTERFACES (XDL 35-5P & XDL 56-4P only)
Full remote control facilities are available through the optional RS232, GPIB and USB interfaces.
Setting and readback resolutions are the same as for the Output and Meter specifications
respectively.
