This section of the manual is a general introduction to the controls and operation of the
instrument and is intended to be read before using the power supply for the first time.
In this manual front panel keys, connections and display indicators are shown in capitals,
e.g. STORE, ESCAPE, OUTPUT, JOG. Messages shown on the 7-segment display are printed in
a different type-font, e.g.
characters as they are shown on the 7-segment display.
Switching On, Output On/Off
The power switch is located at the bottom left of the front panel.
At power-up the default behaviour is for the instrument's settings to be restored to those
automatically saved when it was switched off, but with the Output always off. However, the user
can change this default setting such that the Output is also restored at power-up to its status at
power-down, see the Extra Functions section.
The DC output is switched electronically with the ON/OFF key; the key illuminates when the
output is on.
Keypad
Only the principles of operation are outlined here; the setting of individual parameters is given in
detail in later sections.
The paramount consideration in designing the user interface has been to make changing settings
as 'safe' as possible (i.e. with minimal risk of accidentally applying excessive voltages to a target
system) whilst achieving ease of use. This has been achieved by requiring the user to confirm
(OK) new numeric settings, with the option to ESCAPE at any point or even to simply pause until
the operation times-out and the instrument returns to its orginal settings.
In addition a buzzer, illuminated keys, LED indicators and display messages prompt, guide or
warn the user such that entry or control errors are minimised. Where some of these features (e.g.
beeps or flashing indicators) are considered unnecessary by regular users, the option exists to
disable them, see the Extra Functions section.
Under normal conditions the numeric keypad is disabled; pressing any key will cause the buzzer
to make a double beep, indicating an illegal operation. To set a voltage or current with the
keypad press the V or I NUMERIC SET key; the appropriate display shows 0·000V or 0·000A with
the digit to the left of the decimal point flashing. Digits are entered in response to the flashing
prompt, together with the decimal point at the appropriate time, and the entry is confirmed with
the OK key. If OK is not pressed within 10 seconds of the last numeric key the entry is cancelled
and the display returns to its original setting. If ESCAPE is pressed anywhere in the entry
procedure, entry is cancelled and the display returns to its original setting.
The OK key is used to confirm most keypad entries. At all other times it becomes the VIEW V/I
LIMITS key and pressing it will cause the display to show preset output voltage and current limit
for 3 seconds; during this period the LIM indicator in the display flashes.
Pressing SHIFT illuminates the key and gives the numeric keys the functions marked above them
(e.g. STORE, RECALL, etc.). When a function is selected by pressing one of these keys SHIFT
is cancelled (the SHIFT key is no longer lit). The further key presses required to complete the
selected function are described in detail in the sections that follow; if no key is pressed within 10
seconds to complete the function, the function with terminate as if ESCAPE has been pressed.
SHIFT is a toggle key; pressing SHIFT again when it has been selected will cancel SHIFT.
SHIFT is also cancelled by ESCAPE, or by pressing SET V or SET I.
