Use SINGLE INPUT SCOPE mode if you want to measure a single signal, INPUT B is turned off.
Use DUAL INPUT SCOPE mode if you want to simultaneously measure two signals.
Using the Function keys
For each test,
one
or more Function
Key Labels
are displayed, depending on the
sub-selec
t
ions possible. The
Labels indicate what the keys do when you press them. (See the following example.)
Pressing a function key that has no label has no effect.
The same Function Key Label can appear in several tests and it performs a similar function.
Examples of Function Key Labels
Two separate functions can be allowed to the same function key.
You can use the function key to toggle between the functions.
When you press , you can select between PARADE and SINGLE cylinder test.
When you press , OHM becomes the active function. When
you press , Diode ( ) becomes the active function. When
you press , OPEN CONTINUITY becomes the active function.
Pressing , CLOSE CONTINUITY becomes the active function.
