Response time is the time from when the sensor measures a charged amount to when the
value is output (either as linear output or judgment output).
The response time changes depending on the settings for the number of samples to average
and calculations.
The measured value is the measurement result displayed on the main display of the
Amplifier Unit in the RUN or T modes.
The measured value is the value after all set processing has been completed, e.g.,
averaging, scaling, distance correction, area correction, and hold.
p.9
The present value is the current measurement result obtained by the target Amplifier Unit.
Some set processing, such as averaging, scaling, distance correction, and area correction,
have been completed for the current measured value, but calculation, and hold, settings are
not reflected.
To display the present value on the sub-display, press the LEFT or RIGHT key in the RUN
mode.
p.9
Linearity is defined as the error in an ideal straight line displacement output when measuring
the standard sensing object. Linearity shows how closely linear output maintains a linear
relationship to the charged amount of the sensing object (i.e., it shows the accuracy of linear
output).
Linear output is analog data output from the linear output line. Either current or voltage
output can be selected.
Linear output is made based on the display value and monitor focus settings.
The actual value that is output (the output value) can also be displayed on the sub-display by
pressing the LEFT or RIGHT key in the RUN mode.
p.70
This is a general term for the HIGH, PASS, and LOW outputs. Judgment outputs are made in
the RUN or T mode based on the display values and the threshold, hysteresis width, and
timer settings.
This is the range (distance) that measurement is possible for the connected Sensor Head.
p.118
Sampling period is the time during which the sensing object is measured when the hold
function is being used.
The sampling period is determined by the trigger mode and the delay time.
