mAs Measurements

2

2-3

From step 2, you can also proceed as follows to do mAs
measurements on input A:

3

In Scope mode display the 

INPUT

A

 

key labels.

4

Open the 

Probe on A

 menu.

5

Select 

Probe Type: Current

,

then

 

accept.

6

Select for example 

1 V/A

, then

accept.

7

Display the cursor key labels (B-
and C-versions are different).

8

Press to highlight  

. Observe

that two 

vertical 

cursors are

displayed.

9

Press to highlight mAs.

10

Highlight the left or right cursor.

11

Move the highlighted cursor to the
desired position on the waveform.

mVs  measurements

When you select 

Voltage

 in the 

Probe on A (B)

 menu,

the F3 key label shows 

mVs

.

mWs measurements

When you are in the Math AxB mode, and you select in
the 

Probe on A (B)

 menu for one channel 

Voltage

 and for

the other channel 

Current

, the F3 key label will show

mWs.
