Where: X is the normal input reading
The displayed units designator for reciprocal readings is "R." You cannot change
this units designator.
Example:
Assume the normal displayed reading is 002.5000Ω. The reciprocal of
resistance is conductance. When the reciprocal math function is enabled, the
following conductance reading will be displayed:
0.400000 R
NOTE The result of the 1/X calculation may be displayed in exponential
notation. For example, a displayed reading of +2.500E+03 R is
equivalent to 2500 R (2.5K R). When using REL, the REL'ed reading
of the input signal is used by the 1/X calculation.
Basic reciprocal operation
1. Select the desired measurement function.
2. Configure and enable the mX+b, percent, or reciprocal (1/X) math function
as previously explained.
3. Apply the signal to be measured to a switching channel input.
4. Close the input channel. The result of the math calculation will be displayed
when a reading is triggered.
