Test
NOTE
The wiring between the power supplies drives the accuracy of
measurements in series operation. Ensure that wire sizes are
sufficient, wires are short, and connections are tightened to
maximize accuracy.
Combine
You can combine the outputs of the channels in series or
in parallel. Series operation mode is only available for CH1
and CH2 of the 2230-30-3 and 2230-30-6. Parallel operation
mode is available for CH1 and CH2, CH2 and CH3, or all
three channels.
Example: Combine V1 and V2 in series
To combine channel 1 and channel 2 when the outputs
are wired in series:
1.
Connect the outputs in series, as shown in the figure.
2. Press the
Menu
key.
3. Use the arrow keys to select
Combine
.
4. Press the
Enter
key.
5. Press the down arrow key to select
V1+V2 Series
.
6. Press the
Enter
key. The screen returns to meter mode.
Verify that the Series indicator is displayed, replacing the
channel 2 voltage and current readings. This indicates
that the power supply is in the V1+V2 series state. The
total output voltage is displayed on Channel 1.
7. Set the channel 1 voltage to the value you want.
