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 ATM3500A.
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
V = Voltage measured by the DMM
R = Shunt resistance value
As to the MX+B setting, “M” stands for “1/R”, “X” stands for “voltage
measured by the DMM” and “B” stands for “Offset, 0”.
Application1.
(via the scanner card and the PT-TOOL software for the multipoint
measurement, but it has some limitations when using it.):
1. Switch the terminal to the rear control.
2.
Build in the necessary current shunt on the R1/R2 location
