SECTION 3 - OPERATION
3.1 GENERAL
This section contains general operating instructions for the Series EL Electronic Load. Refer to
Section 2 for a description of the controls, display and terminals. When loading sources of elec-
trical energy be sure to use appropriate precautions where high-currents and potentially high
voltages may be present.
WARNING
An electronic load can present an extremely low resistance to a source
of electrical energy. in some cases this may be the equivalent of
placing a short circuit at the source output. This may have disastrous
consequences if done unintentionally.
Be sure the load parameter settings are appropriate for the source
being tested.
