Display
The displays shows the voltage on the left (5 digits) and the current on the right (4 digits) for both
the main outputs. These 7-segment displays are also used to show prompts during some of the
function settings (e.g. memory store/recall or remote control address setting) using the limited
'character set' that can be achieved with a 7-segment display; these are necessarily a mixture of
upper and lower case letters.
Above and below the 7-segment display are several secret-until-lit annunciators.
To the right, above the current display, are the indicators which show the selected operating
range: 35V/3A, 15V/5A or 35V/500mA (XDL 35-5T & TP) or 56V/2A, 25V/5A or 56V/500mA (XDL
56-4T & TP); the indicators light beneath the range printed immediately above them and, in the
case of the 500mA range, the indicator is marked mA to emphasise that the current display is now
showing mA.
The other annunciators above the displays are:
CI, indicating that the instrument is in constant current mode;
LIM, which flashes when the VIEW V/I LIMITS key is pressed to show the set voltage/set current
limit in the display;
REM, which lights when the instrument is under control from a remote interface (P models only)
and LAN, which indicates the status of the LAN interface connection (P models only).
Below the three least significant digits of both the voltage and current displays are the JOG
indicators; the appropriate indicator flashes when the jog function is being used, see the Jog
Control section above.
The display of Output 1 can alternatively be used to show the voltage and current of the AUX
output (T models only). Full details are given in the Auxiliary Output section.
