A
Probe
Signal line for supplying the signal to the input
PT
Abbreviation of (voltage) "potential transformer"
Recording length
Total amount of sampling data expressed as number of
increments
Reference junction
compensation
When thermocouples are used, the temperature difference
between the object and the measuring equipment terminal is
measured. Reference junction compensation takes into account
the terminal temperature so that the object temperature can be
directly read.
Ripple component
AC component of noise
r/min
A unit of rotation, signifying the number of rotations per minut
e
(rpm).
Sampling
Measuring an analog waveform at regular intervals
Sampling rate
Rate at which sampling carried out; sampling frequency
Scaling
Conversion of voltage value into a specified unit
Storage
Storing measurement data in the internal memory
Thermal head
Print head of thermal printer
Threshold value
When turning an analog signal into a logic signal, the level at
which the measured value is divided between High and Low.
Trigger
An event that causes a certain action (such as starting or
stopping a measurement) to happen.
Unbalanced input
Using a two-pole input in such a way that one pole carries the
signal referenced to the other pole.
Word
A unit for expressing digital data. The digital data for one inpu
t
signal point after conversion.
