Special MANU Test Mode (000)
Special Test
Mode Overview
When MANU number 000 is selected, the
special test mode is activated. Under the special
test mode, the voltage can be changed during a
test, in real time (ACW, DCW only). The test
function can also be changed when in READY
or VIEW status, unlike under normal operation.
Separate settings can be saved under the special
test mode for each of the testing functions:
ACW, DCW, IR and GB. This means a different
ACW, DCW, IR and GB test setup can be saved
for MANU number 000.
The GPT-9901A/9902A/9903/9903A and 9904
have access to the sweep mode function. The
sweep function creates a graph of one of the
ACW, DCW, IR or GB tests in the special
manual mode. The graph will plot the output
voltage, current or resistance versus time. After
the test has been completed, the test current,
voltage or resistance at any point in time can be
viewed in the graph.
Below is an example of the resultant sweep plot
of a DCW test where a DC voltage is ramped
up to a user-defined level until the HI SET
current level has been tripped or the test time
runs out.
