Technical data

The selection of the input mode DIRECT and the activation of the outputs with the OUT A/B
button [15] causes the previously set voltage and current values to appear on the display [5].
Now the cursor blinks at the previously input position. Using the V button, [11], I button [11],
A/B button [12] and the cursor buttons [13] the parameters can be consecutively set on the
display [5] and at the outputs of sources A [2] and B [3].
The actual output parameters which the instrument internally measures can be called by using
the ESC button [20]. Here, no inputs can be made and the cursor does not appear. Only after
actuating the V button [11] or I button [11] values can be changed again.
Parameter setting for the input mode INDIRECT is described in the following chapters 6.4.2
and 6.4.3.
6.4.2 Voltage Setting
On pressing the V button [11] the voltage can be set and the following message appears on
the display [5]:
VOLTAGE_A
SET :[ ]
or
VOLTAGE_A
LIM :[ ]
SET is displayed if the current source is used as a constant voltage source. If LIM is displayed,
the source works as a constant current source.
The voltage value is indicated in brackets [ ]. It can be changed using the cursor buttons
[13]. The new setting is saved with the ENTER button [12]. If the former state is to be kept,
the ESC button [12] has to be pressed. In both cases the unit reverts to the starting state.
The letter A or B behind VOLTAGE_ indicates the previously set source. Sources A and B can
individually be addressed using a A/B button [12] in independent operating mode.
6.4.3 Current Setting
On pressing the I button [11] the current can be set and the following message appears on the
display [5]:
CURRENT_A
SET :[ ]
or
CURRENT_A
LIM :[ ]
SET is indicated if the current source is used as constant current source. In case LIM is
indicated, the source works as constant voltage source.
The current value is indicated in brackets [ ]. It can be changed using the cursor buttons
[13]. The new setting is saved with the ENTER button [12]. If the former state is to be kept,
the ESC button [12] has to be pressed. In both cases the unit reverts to the starting state.
The character A or B behind CURRENT_ indicates the previously set source. Sources A and B
can individually be addressed using a A/B button [12] in independent operating mode.
