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 period, e.g. from seconds to milliseconds (the value is multiplied 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 maximum period of the measuring input signal. It
is recommended that the value of this setting should be about twice the maximum
period of the measuring signal. The meter will display the upper range limit symbol,
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.
5.4.1.4
Frequency measurement
Measurement main features:
•
Wide range of frequency measurement (from 0.02 Hz do 20,000 Hz) with the
possibility of limiting the measurement time (lower value of frequency).
