4.3.6 MX+B

Definition
This mathematical function multiplies a measurement reading (X) by a
specified scale factor (M) and add an offset (B) automatically. The
answer (Y) will then be shown on the display according to the following
equation.
Y=MX+B
This is especially useful when you need to do slope calculations on a
series of measurements.
The values of the "M" and "B" can be changed through the configuration
of this function and they are stored in a volatile memory and will be
cleared after the meter has been turned off or a remote interface reset.
You can either use front panel or remote interface to perform this
function and set these two constant.
How to use MX+B function
You can use MX+B function from the front panel operation or the remote
interface operation.
We provide two application examples for your reference. The first one is
that if you have to use scanner card to obtain the current value (For more
specification information, refer to the scanner card user's guide.).
Second, if the input current source you want to measure exceeds the
current specification, 3A, of the M3500A.
Then the DCV/ACV and MX+B functions would be helpful. The current
value is calculated through the equation as follows. "I=V/R".
Where: I = Current being determined
