Overview of Scale/Offset Math Menu
The Scale and Offset functions within the Math menu allow you to perform simple
mathematical operations on the measurement result before it is displayed. The Scale
and Offset functions allow for multiplication and addition. Modification of the
displayed measurement by these math operations is represented by the following
equation:
(Measurement × Scale) + Offset = Displayed Result
The math operations can be used, for example, to subtract systematic errors or display
the percentage difference between signals. Also, the overall math operation can be
disabled and then re-established without having to re-enter constants.
The menu items of the Scale and Offset Math functions allow you to:
• enter a desired multiplication factor for a measurement (SCAL:).
• enter a desired addition or subtraction value for a measurement (OFFS:).
• get and display the last measurement value, and use it as a negative offset (SET
REF: NO or YES).
• disable or enable the Math mode (MATH: OFF or ON)—Note that the Math
mode is automatically enabled when you enter the scale and/or offset value(s);
thus, the primary function of this menu item is to allow you to turn the Math
mode off.
• get Help, which displays the equation “(MEAS X SCALE) + OFFS =
RESULT ” to tell you how the scale and offset results are computed by the
Counter (MATH HELP: NO or YES).
