4 - 56 HOW TO USE THE INSTRUMENT
MATHEMATICS MULTIPLY
You can activate a second process MATH 2. This way, two processes can run at
the same time.
- Connect the Probe Adjust signal to channel 1 and channel 2 and turn on
both channels.
- Press the ’MATH 2’ softkey in the MATH menu.
The menu displays the MATH 2 functions. MATH 2 offers the same functions and
parameters as MATH 1.
For MATH 2 the default parameter is ’mult’.
Using ’MULT’ means that two selected traces are multiplied together and that the
result is stored in ’m2’.
- Press the softkey next to MATH 2 to enter the MATH 2 submenu.
Observe that the submenu is now optimized for the multiplying process. You can
select between all active traces or memory locations to be the source traces.
- Turn the TRACK control to select ch1.
-
Turn the
∆
control to select ch2.
- Press the ENTER softkey to return to the main menu.
- Press the softkey next to ’on off’ to turn MATH 2 on.
The multiplied trace of channel 1 and channel 2 is instantly displayed on the
screen. At this time the resulting trace is stored in memory location ’m2’.
One example of this process is to multiply voltage across a component and
current through that component to find dissipated instantaneous power.
- Switch MATH 2 off again.
