Fundamental Concept of E-Load
What is Electronic Load?
It absorbs the energy from Power Supply and transfers to another type of energy
and to be a storage or dissipated equipment.

Required Equipment List for Test
1. DL3031/A/3021/A Electronic Load
2. DP832A Power Supply
3. Testing cables
4. Ultra Sigma Software

RIGOL TECHNOLOGIES, INC.
DL3000 Test Procedure
1. Connect the test cable from Power Supply to Eload input terminals, turn
on the CH1 of DP832A and set the Voltage value to 5V.
2. The S+, S- terminals should be also connected because it can make
the measurement more accurate and even compensate the voltage drop
when the DUT offers large current through the load.
