Measured value on the reference channel
–
The measured value of the channel is set to the
difference with respect to the measured value of the
reference channel
Low-cut
Converts the unit to obtain the measured value. Takes the square root of the input value and converts
the unit to obtain the measured value.
Counts the pulses. Use the computation channels
(/M1, /PM1, and /PWR1 options).
You can apply a logarithmic voltage that has been
converted from a physical value to the FX, and then use
the FX’s Log scale (logarithmic scale) to display and
record the physical value.
Measure the measurement elements of electrical power.
Use the computation channels (/M1, /PM1, and /PWR1
options).
