To use Auto Set, be sure that the test parameter of Output Voltage and Ramp Time
have been set to the values that will be used for the Final test and connect the test
cables and/or test fixture between the instrument and DUT. If the scanner is to be
used then the scanner channel must also be set, and then press the TEST button.
The instrument will apply the voltage that has been entered for this memory-step
selection.
Please be aware that the program will activate high voltage on
the output connector while the Test button is pressed.
The program will read the charging current of DUT and set the Charge-LO current
at approximately one half (1/2) of the reading. The display will show:
Charge-LO = XXX.X

to Auto Set
The value showing on the display is the Charge-LO setting and is not the reading of
the charging current of the DUT.
Then press the
Ù
or
Ú
key to advance the program to another test parameter or press
the EXIT key to exit from the setting mode to the operation mode.
2.2.7 Ramp-HI
Advance the menu to the Ramp-High parameter. The display will show:
Ramp-HI = ON

Ramp-HI =

to Select
Use the ENTER key to select the Ramp-HI mode, then press the
Ù
or
Ú
key to
advance the program to another test parameter or press the EXIT key to exit from
the setting mode to the operation mode.
The Ramp-HI function is active during the Ramp period only. Ramp-HI will allow
current higher than the normal HI-Limit current setting of the DC Withstand Voltage
test to avoid false failure due to charging current.
2.2.8 Arc Sensitivity setting and Arc Fail selection
Advance the menu to the Arc Sense parameter. The display will show:
Arc Sense = 1 - 9
Range : 1 - 9 9 = High
Use the Numeric keys to enter the Arc Sense setting, then press the ENTER key.
The numeric value is proportional to the amount of sensitivity, i.e. 9 is the highest
sensitivity. The program will store the Arc Sense setting and advance to the ARC
