4.1.5 Select Trigger Source(Trig Source)

This menu item is used to select the trigger source.
IT-M3100D series power supply supports the following trigger sources:
key to make the parameter in modification.
•
Off: default value, indicates turn the sense function off.
•
On: indicates turn the sense function on.
On (default): For test scenarios other than battery charging tests. After the
Bleeder is turned on, when the test is finished and the output is turned off,
the voltage can be dropped quickly.
Off: For battery charging test scenarios. Since some devices inside the in-
strument can absorb power, when the test is finished and the battery is still
connected to the test circuit, these devices will still discharge the battery
even if the output is turned off or the instrument is powered off. Therefore,
before connecting the battery to the test circuit, set Bleeder to Off to discon-
nect the bleeder circuit to avoid this problem.
Turning off the Bleeder can omit the diode which is used to prevent re-
verse current during battery testing.
