13. Press
ENTER
to save your settings and return to the main menu.

9
until a valid trigger level is found.
15. Press
MENU
to exit the menu structure and display pulse current measurements.
TRIG NOT DETECTED message
The TRIG NOT DETECTED message is displayed when specific TLEV settings, coupled with
corresponding current range, have been set and a trigger has not been detected. Refer to
Table 3-
2
for the message preconditions.
NOTE
If the trigger level is still too low or too high, the TRIG NOT DETECTED
message will be displayed briefly. Note that it may take a few seconds for the
message to appear (see
TRIG NOT DETECTED message
for more
information).

Depends upon the OUTPUT:
If OFF, the message will appear.
If ON, display of the message will depend on the trigger level setting. If trigger level setting greater than the expected low
measurement and less than the expected high measurement, the message will not appear.
For example, if the expected pulse high value is 2.2 A and the expected pulse low value is 0.5 A, the output is on, and
the current range is 5 A, notice the following results:
Setting 0.3 A
TRIG NOT DETECTED is displayed (setting too low).
Setting 3.0 A
TRIG NOT DETECTED is displayed (setting too high).
Setting 1.1 A
The message will not display (setting correct).
