I2+I3 parallel
The wiring between the power supply output terminals affects the accuracy of measurements in this
mode. Make sure that wire sizes are sufficient, wires are short, and connections are tightened to
ensure maximum accuracy. See Wire specifications (on page 1-4
) for wire size guidelines.
When I2+I3 Parallel mode is enabled, the voltage range of CH2 is changed to the smaller one of
CH2 and CH3. The maximum output voltage is 5 V.
To combine channel 2 and channel 3 when the outputs are connected in parallel:
1. Connect the outputs in parallel, as shown in the following figure.
Figure 9: CH2 and CH3 outputs connected in parallel
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 I2+I3 Parallel.
6. Press the Enter key. The screen returns to meter mode. Verify that the Para indicator is
displayed, replacing the channel 3 voltage and current readings. This indicates that the power
supply is in the I2+I3 parallel state. The total output current is displayed on channel 2.
