Manual Operation
Main Outputs
New users should first read the Initial Operation chapter which describes the operating principles
of the keypad and rotary jog control. The following paragraphs describe the independent
operation of either Main Output. To select which output is to be controlled by the keypad/Jog
controls it is first necessary to select that output by pressing the appropriate CONTROL key
(1 or 2); the key lights to show that it is the selected output.

The additional features available in LINK mode (both Main Outputs selected) are described in the
Main Outputs – Link Mode section later in this manual.

Set Voltage
The left-hand display shows the set voltage to a resolution of 1mV, except when the instrument is
in constant current (CI) mode. In CI mode the actual output voltage (which will be less than the
set voltage) is shown and the display resolution is 10mV; the least significant digit (1mV
resolution) is always displayed as a zero.
in constant current (CI) mode. In CI mode the actual output voltage (which will be less than the
set voltage) is shown and the display resolution is 10mV; the least significant digit (1mV
resolution) is always displayed as a zero.
The voltage can be set directly from the numeric keypad: press the NUMERIC SET V key, enter
the new value using the numeric keys and confirm by pressing OK. The broad principles of
keypad entry are explained in the Initial Operation chapter, which should be read by new users.

keypad entry are explained in the Initial Operation chapter, which should be read by new users.
When SET V is pressed the display shows 0·000; a new voltage is then entered (e.g. 12·345V is
entered as 1, 2, ·, 3, 4, 5) and confirmed by OK. The position of the decimal point in the display is
fixed to reduce the risk of entering a wrong value. As a consequence, and to avoid the need to
enter leading zeroes (e.g. 2·345V is entered as 2, ·, 3, 4, 5, OK), numbers to the left of the
decimal point are shown slightly differently to the numbers to the right of the decimal point during
number entry; this is self-evident during number entry.

The minimum voltage setting is 0·000V; the maximum setting is 35·000V (15·000V on the 15V/5A
range).
range).
Pressing OK at any point will set the voltage entered with any remaining digits set to zero,
e.g. 1, 2, ·, 3, OK will set 12·300V; 1, OK will set 1·000V; pressing OK immediately after SET V
(while the display shows 0·000V) will set 0·000V.
e.g. 1, 2, ·, 3, OK will set 12·300V; 1, OK will set 1·000V; pressing OK immediately after SET V
(while the display shows 0·000V) will set 0·000V.
Pressing ESCAPE at any time during the sequence, or making no further key press within
10 seconds of the previous one will cause the display to return to its original reading before
SET V was pressed.

key entry will be ignored.
The voltage can also be set using the Jog control. Pressing JOG SET V will illuminate the V key
and the JOG indicator under the digit that was last jogged will flash. Whilst the V key is lit, each
further press will move the JOG indicator one digit to the left; the selection 'wraps round' such that
when the largest value of jog increment has been reached the next press returns it to the lowest.
The default position at power-up is under the LSD, i.e. the lowest jog increment is selected. The
jog steps that can be selected are 1mV, 10mV and 100mV.

With jog enabled the output voltage can be incremented or decremented with the rotary jog
control with a step resolution indicated by the position of the flashing JOG indicator. The output
immediately follows the setting, i.e. no OK is required. If the output goes into constant current
mode (indicated by the CI indicator flashing) the left-hand display shows actual voltage not set
voltage. If JOG SET V is selected the JOG indicator under the selected digit will flash at half
speed ('lazy' flash). To observe the effect of jogging the set voltage it will be necessary to either
turn the output off (so that the display permanently shows the set voltage) or to press
VIEW V/I LIMITS which causes the set voltage to be displayed until 3 seconds after movement of
the jog control ceases.
