Load Connection
WARNING : To satisfy safety requirements, load wires between the electronic load
and the device under test (DUT) should have a current rating high enough not to
overheat while carrying the short-circuit output current. Never make connections
between the electronic load and a DUT while the electronic load inputs are turned ON
and/or the DUT has live power at its output.
Before connecting the device to be measured to the electronic load, please remove the cover on
the output terminals of the load and cover it after completing the connection. Please pay attention
to the type, length, and polarity when wiring. Avoid using wires of minimum specification of
heating, which are unable to supply good load regulation. Generally speaking, if the wires are short
enough, they can control a voltage drop of less than 0.5 V. In addition, bonding them together can
reduce induction and noise. Connect wire from positive terminal of module to positive terminal of
device. Similarly, connect the corresponding negative terminal. Figure 11 illustrates a typical
connection of the module with the device to be measured.
