Sampling
Measuring an analog waveform at regular intervals
( Appendix 2.1)
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

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
