Press F5 to return to the original menu level. (This return also occurs automati-
cally after about 10 s)
The preselect counter mode can be used with either single or with repetitive
discharges.
Each time there is a discharge the counter content is decremented by 1.
In the repetitive mode the discharge sequence is started when the trigger
button is first pressed and is halted when the button is pressed a second time.
The sequence can be continued by pressing it again.
Pulse triggering is terminated when the counter content reaches 0000.
F5 reloads the preselect counter with the original value.
Once the counter reaches 0000 and the procedure has been stopped, the
counter can also be reloaded with the original value again and the test sequence
started anew simply by pressing the trigger button.
5.10 Automatic polarity switching
The IEC standards call for equal quantities of positive and then negative dis-
charges to be applied to a test point. The NSG 435 can execute this function
automatically.
The automatic polarity switch operates in conjunction with the preselect
counter.
