to confirm,then select ISO16750-2,press to confirm
3. Press or to select Short voltage drop,press to confirm.
4. Press or to select 12V system,press to confirm.
5. Press to select Off/On,press or to select On,press to confirm.The
Trig indicating lamp will be lit and display on the VFD.
6. Press
to quit menu operation
7. VFD will display Short voltage drop in the lower right corner
8. Press ,turn on the output
9. press
+ (Trigger)to generate a trigger signal.The DC source will
output Short voltage drop waveform.
Note
Please make sure the trigger source is selected in MANUAL item in above operations(refer to step
9th).And user need to turn on the internal dummy load to speed up the falling time during
ISO16750-2/DIN40839 waveform operations.
2* Profile for the reset test
This test verifies the reset behaviour of the DUT at different voltage drops. This test is
applicable to equipment with reset function, e.g. equipment containing microcontroller.
Apply the test pulse simultaneously in figure below to all relevant inputs (connections)
and check the reset behaviour of the DUT.Decrease the supply voltage by 5 % from the
minimum supply voltage, USmin, to 0,95USmin. Hold this voltage for 5 s. Raise the
voltage to USmin. Hold USmin for at least 10 s and perform a functional test. Then
decrease the voltage to 0,9USmin. Continue with steps of 5 % of USmin, as shown in
Figure 6, until the lower value has reached 0 V. Then raise the voltage to USmin again.
How to recall “Profile for the reset test” waveform from menu (take 12V system as a example):
1. Press + (Menu) to enter the menu operation
2. VFD displays SYSTEM CONFIG FUNC. INFO, Press to select FUNC. Press
to confirm,then select ISO16750-2,press to confirm
