Basically, Fuse test has Trip (fuse) and Non-Trip (no fuse) 2 types.
Fuse Test setting parameters include test current (Istart), test time (Time), test repeat
Number REPEAT TIME etc.
In the Trip fuse test, it is used to test when the current occurs too large abnormalities must
Be able to provide the protection of the circuit break that means current protection
Components need the fuse action, therefore the test current needs to be greater than the
Fuse current rating.
For the trip test mode of the 3270 series AC & DC electronic load, the LCD shows the
Repeat times and the blow time of current protection component after the tested fuse blows.
In the Non-Trip fuse test, the current protection component is required to achieve non-blow
Action, so the test current needs to be lower than the fuse current rating that is used to
Verify the fuse must not blow during normal current range.
For the Non-trip test mode of the 3270 series AC & DC electronic load, the LCD display
Shows Repeat number information after the tested fuse does not blow.
