Operation

In the example shown in Figure 15, the internal trigger

threshold has been set to 8% (shown as a dashed line).

Pulse A will definitely not generate a reliable trigger.

Pulse B may generate a trigger, but not reliably. Pulses C

and D will definitely generate reliable triggers.

A full-scale signal on one range may not trigger on the

next higher range unless the trigger level is set to less

than 10%. For example, a near full-scale signal of 280 mJ

on the 300 mJ range is less than 10% of full scale on the

next higher range (3 J), and would therefore not trigger

the reading. To obtain reliable triggering in this instance,

adjust the trigger level to less than 8%.
