Ensure the warm-up criteria have been met, as described in the Performance verification conditions.
To assure accurate measurements, the voltmeter must be connected as closely as possible to the
front panel of the device under test (DUT). A solution is to use fork spade terminals between the
electronic load and the DUT, and banana plugs between the DUT and voltmeter. An alternative
solution is to use fork spade terminals for both connections at the DUT. For details, see the following
figure.
