NSG 435 ESD simulator
5.4 Air-/Contact-discharge
F1 toggles between air-discharge and contact-discharge and vice versa.
The change to contact-discharge is prevented if:
The voltage set for this operating mode is too high, i.e. over 9 kV
The repetition frequency set for this operating mode is too high, i.e.
over 10 pulses/s
The instrument notifies the error with a beep and the erroneous setting blinks
for 5 s.
When working with fixed voltage levels, the relevant value is automatically
loaded upon toggling between the air/contact-discharge mode.
The corresponding test finger must, of course, be attached to suit the particular
discharge mode:
Air-discharge = rounded test finger
Contact-discharge = pointed test finger
