Usage
state = dmm.math.format
dmm.math.format = state
state
Math operation to be performed on measurements:
▪ dmm.MATH_NONE or 0
▪ dmm.MATH_MXB or 1
▪ dmm.MATH_PERCENT or 2
▪ dmm.MATH_RECIPROCAL or 3
Details
This is not available for "nofunction". If this command is queried when "nofunction" is
selected, nil is returned. If it is written when "nofunction" is selected, an error is returned.
If you set this attribute to dmm.MATH_NONE, math operation is disabled, even if math operation
(dmm.math.enable) is enabled.
Use a setting of dmm.MATH_MXB to have
where:
• Y is the result
• X is the normal measurement
• m is the user-entered constant for scale factor (dmm.math.mxb.mfactor)
• b is the user-entered constant for offset (dmm.math.mxb.bfactor)
If you are using relative offset measurement control (dmm.rel.enable), the relative offset reading is
used for X.
Use a setting of dmm.MATH_PERCENT to have:
where:
• Percent is the result
• Input is the normal measurement (if using dmm.rel.enable, it will be the relative offset value)
• Reference is user entered constant (dmm.math.percent)
Use a setting of dmm.MATH_RECIPROCAL for 1/X operation, where X is normal or the measurement
value with relative offset applied.
The math operation is performed before any of the enabled limit testing.
