Page 46: Output Connections
The only time the sense jumpers should be disconnected from the output is when remote sensing. Keysight recommends 22 AWG wire used for sense jumpers as well as for remote sensing. Ferrules are recommended for all wiring, especially when using stranded wires (see Items Supplied).
Page 47 4. Because of wire inductance considerations, it is also recommended that you keep your load leads twisted, tie wrapped, or bundled together. Refer to Remote Sense Connections for additional information.. 5. Wire ferrules are included with this product for AWG 12 and 4 mm 2 stranded wires. Keysight MP4300 Series Operating and Service Guide...
Page 48: Single Load Connections
Disconnect the connector plug to make your wire connections. The 4-pin output connector accepts wires sizes from AWG 8 to AWG 24. Wire sizes smaller than AWG 20 are not recommended. Keysight recommends either using solid wires, or attaching ferrules to the end of stranded wires.
Page 49 Additionally, when the output is disabled when operating in diode mode, the front panel voltage readback switches from sensing at the anode of the blocking diode, to reading the voltage at the remote sense terminals. This results in a change in the front panel voltage reading. Keysight MP4300 Series Operating and Service Guide...

Page 93: Current Sinking Operation
4 Using the Modular Power System Current Sinking Operation Current Sinking Regenerative Operation Keysight MP4362A power modules have a fixed sinking current limit of 0.5 A. Refer Output Quadrants for details. Current Sinking Current sinking, also referred to as down-programming, is the ability to pull current into the positive terminal of the power supply.
Page 94: Programming Output Protection
Using Power Limit Protection Introduction Keysight MPS protection functions disable the channel output to protect the device under test (DUT) as well as the channel. A front panel status indicator turns on when a protection function has been set. Most protection functions are latching - meaning that they must be cleared once they have been set.

The performance verification tests are recommended as acceptance tests when you first receive the instrument. The acceptance test results should be compared against the instrument specifications. Keysight Technologies recommends that you repeat the performance verification tests at every calibration interval. This ensures that the instrument will remain within specifications for the next calibration interval and provides the best long-term stability.
