ELR 9000 Series
► How to adjust values with the rotary knobs:
1. First check whether the value to be changed is assigned to one of the rotary knobs. The main
screen displays the assignment:
2. If, as shown in the example, the assignment is voltage (U) left and the current (I) right, and
it is required to change the resistance or power, then the assignments can be changed by
tapping this touch area. A set of selection areas then appears in which the assignments can
be changed.
3. After successful selection, the desired value can be set within the dened limits. Selecting a
digit is done by pushing the rotary knob which shifts the cursor clockwise (digit will be under-
lined):
Changing to R/I assignment is only possible while the DC input is switched off. If it is switched
on, a message will appear in the display which has to be acknowledged The previous assign-
ments remain.
► How to adjust values via direct input:
1. In the main screen, depending on the rotary knob assignment, values
can be set for voltage (U), current (I), power (P) and resistance (R) via
direct input by tapping on the set/actual value display areas, e.g. in the
uppermost area of voltage.
2. Enter the required value using the ten-key pad. Similar to a pocket
calculator the key clears the input.
Decimal values are set by tapping the point key. For example, 54.3V
is set with and .
3. The display reverts to the main page and the set values take effect..
If a value is entered which is higher than the adjustment limit, a message appears and the
entered value is reset to 0 and not accepted.
Direct input of a resistance or current set value in R/I mode is only possible if the DC input is
switched off.
3.3.7 Switching the DC input on or off
The DC input of the device can be manually or remotely switched on and off. This can be restricted in manual
operation by locking the control panel.
► How to manually switch the DC input on or off:
1. As long as the control panel is not fully locked press the pushbutton ON/OFF.
2. This button toggles between on and off, as long as a change is not restricted by an alarm or the device is
locked in “Remote”. The condition is displayed as either “Input ON” or “Input OFF”.
► How to remotely switch the DC input on or off via the analog interface:
1. See section “„3.4.4. Remote control via the analog interface (AI)“.
► How to remotely switch the DC input on or off via the digital interface:
1. See the external documentation “Programming Guide ModBus & SCPI” if you are using custom software,
or refer to the external documentation from LabView VIs or other relevant software provider.
