z High Voltage Trigger On: Measures and displays
actual high voltage at the ESD Simulator's tip
z High Voltage Trigger Off:
Before tip voltage has decayed to below 300-500V,
continues to measure and display tip high voltage
After tip voltage has decayed to below 300-500V,
displays "Program Voltage" -- the voltage that will
appear at the tip when the high-voltage trigger is
depressed
Program Voltage Adjust: Multi-turn, long-life
potentiometer, mounted in thumb-accessible position on
ESD gun handle.
Discharge Ground Strap: Inductance equivalent to that of
IEC-specified return, but with insulation adequate for
25kV. Length ~ 2000mm, or 6.5ft.
Normal / Slow Ramp Selector
z Slow Ramp Position: In Slow Ramp mode, for
repetition rates of one shot per 3 seconds and one
shot per 10 seconds, the high-voltage ramps up
slowly enough to permit the digital voltmeter to
display the voltage at which the simulated ESD
breakdown occurs
z Normal Ramp Position: Preferred for most other
work.
z Normal ( Single-Shot ) / Burst Selector: In Burst
position, allows realistic simulation of multiple
discharges even when the ESD tester is on a tripod
or is otherwise in a fixed location
