period of the measuring signal. The meter will display the value 0, if during the time
set by this setting a full period of the measuring signal is not present.
•
MAVG – number of the measurements with a period based on SAVG setting which
is averaged using the moving window method. The setting defines the window width
and the averaging time of the measurements. The minimum and maximum values
are registered within the defined window range.
•
MatH – type of the mathematical operation converting the value of the measuring
quantity. The user can select the type of operation or disable the function by
selecting
NONE setting.
•
CFtIM – not applicable.
5.4.1.5 Rotation speed measurement
Measurement main features:
•
Wide range of rotation speed measurement (frequency measurement from 0.02 Hz
do 20,000 Hz) with the possibility of limiting the measurement time (lower value of
speed).
•
Automatic conversion of the measuring signal into speed expressed in revolutions
per minute.
•
High measurement resolution.
•
Programmable measurement time (gating).
•
Automatic change of the measurement method depending on the frequency of the
input signal (counting the internal pulses within the input signal period or counting
the number of the external pulses in the set gating time).
•
High frequency of the internal reference signal generator (39 MHz).
•
Input waveform filtering (for duration of a given level > 50

s).
•
Additional input signal period measurement.
•
Possibility of simple measurement conversion by multiplying or dividing by a
constant - determination of the number of pulses per one rotation.
•
Possibility of measurement averaging using the moving window method with
registering the minimum and maximum value in a given averaging time.
•
Active math functions.
•
Active individual characteristic.
