Probe Calibration A procedure that adjusts the
ScopeMeter test tool internally to compensate for
resistance variations between probes.
Probes Measuring conductor that connects the
ScopeMeter test tool to a circuit; specifically for use in the
BNC jacks.
Pulse A waveform that increases from a constant value,
then decreases to its original value.
Pulse Trains A repetitive series of pulses.
Pulse Width The duration from the beginning to the end
of a signal's on-time or off-time.
Range The quantity between two points or levels.
Recall The function of loading a stored Setup, Screen,
or Waveform back into the ScopeMeter test tool.
Recurrent The ScopeMeter test tool continuously
(recurrently) updates the display. This gives a dynamic look
at the waveform activity as it occurs.
Repetitive Pulse A signal with a regular pattern or
frequency.
Rise Time The time between the 10% and 90% points of
the first slope after the left cursor of a waveform.
Rising Slope The part of a waveform displaying a rise in
voltage.
Root Mean Square (RMS) Conversion of AC voltages
to the effective DC value.
Roll Visual log of a waveform activity that is useful when
measuring lower frequency signals.
RPM Engine speed expressed in Revolutions Per
Minute.
Sample A momentary reading taken from an input
signal. The ScopeMeter test tool takes a series of samples
to display a waveform.
Sampling Rate The number of samples taken from a
signal every second.
Screen The complete image of the display.
Scope Mode In this mode, the ScopeMeter test tool
works like a digital oscilloscope.
Setup Series of adjustments necessary for the
ScopeMeter test tool to display a waveform or reading.
Sine Wave A common curved waveform that is
mathematically defined.
Single Shot Allows the ScopeMeter test tool to capture
a single event.
