•
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 period measurement.
•
Possibility of simple measurement conversion by multiplying or dividing by a
constant.
•
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.
Configuration parameters:
•
SCAL
– selection of the operation to be performed in the measured period of the
input signal. Possibility to select division or multiplication by the value defined by
CONSt parameter.
•
CONSt
– defines the value by which the value of the measured period will be
multiplied or divided. This setting enables a quick change of the basic unit of the
measuring frequency, e.g. from Hz to kHz (the value is divided by 1000).
•
CAUTO
– not applicable.
•
tL
– minimum duration in microseconds of the low input level (inactive state) before
it is considered as the low level. Low level filtering is active for tL setting higher than
50
s.
•
tH
– minimum duration in microseconds of the high input level (active state) before
it is considered as the high level. High level filtering is active for tH setting higher
than 50
s.
•
bCtrL
– not applicable.
•
SAVG
– measurement period (gating) of the input waveform expressed as a
multiple of 100 milliseconds. This setting also defines the maximum duration of the
measurements, thus defining the minimum frequency of the measuring input signal.
It is recommended that the value of this setting should be about twice the maximum
