Arc Detect And Arc Sensitivity Selection; Ramp-Hi Selection (Dc Units Only) - Associated Research HypotMAX 7705 Operation And Service Manual

5.2.9. Arc Detect and Arc Sensitivity Selection

Advance the menu to the Arc Detection selection. The display will show:
Arc Detect =
<ENTER> to Select
Use the ENTER key to toggle the Arc Detect mode, then press the ∧ or ∨ key to advance the
program to the Arc Sense parameter or press the EXIT key to exit from the setting mode to the
operation mode.
Advance the menu to the Arc Sense parameter. The display will show:
Arc Sense =
Range : 1 - 9 9 = High
Use the Numeric keys to enter the Arc Sense setting, and 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 Connect mode selection
automatically.
For the model 7715 the ARC Sense Range changes from 1 to 7 when output voltage is set for
15 kV or more.
If the Arc Detect mode is set to ON, the program will indicate an arc failure when the arc
current is over the setting and the program will shut down the test immediately.
If the Arc Detect mode is set to OFF, the program will not indicate an arc failure when the arc
current is over the setting.

5.2.10. Ramp-HI selection (DC units only)

Advance the menu to the Ramp-High parameter. The display will show:
Ramp-HI = ON
<ENTER> to Select
Use the ENTER key to select the Ramp-HI mode, then press the ∧ or ∨ 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.
