5. Set the current supply to output the first current test point (see Ta b l e 4 ).
Push the Output button, if necessary to verify the current supply is in operate mode.
6. Momentarily push
on the DUT.
Wait for the DUT to complete the measurement. Record the current indication on the DUT
in the test record.
Note
Watch the current supply during this measurement. If it does not go into constant
current mode briefly, then the voltage setting is too low. Increase the voltage of the
current supply and retry step 6 until the current supply goes into constant current
mode briefly. Additionally, check a range of about 0.1 V to see if the current indication
on the DUT stays constant. A constant current indication, even with a change of 0.1 V
from the current source, indicates that there is enough voltage output to allow the
current source to enter into constant current mode.
7. Set the current supply to output the next current test point (test points are in Ta b l e 4).
8. Repeat steps 6 through 7 for all test points.
9. Set the current supply to standby mode.
