4.1 SETTING UP GENERAL MEASUREMENT PARAMETERS – GENERAL SETTINGS
The General Settings list allows you to set
up general measurement parameters:
measurement start delay (Start Delay),
maximum delay period for the
synchronization with RTC (Start Sync.),
measurement period (Integration Period),
repetition of measurement cycles
(Repetition Cycles), RMS detector type
(RMS Integration), RMS detector type for
statistic results (Statistics), day time hours
(Day Time Limits) and time window for the
LRm results (Rolling Time).
Delay of measurement start
The Start Delay parameter defines the delay period from the <Start> keystroke
to the real start of the measurement (digital filters of the instrument constantly
analyses the input signal even when the measurement is stopped). This delay
period can be set from 0 second to 60 seconds.
Synchronisation of measurement start
The Start Sync. parameter defines synchronisation points with the instrument’s
RTC and can be set as: Off, 1m, 15m, 30m and 1h. For example, if 1h is
selected, the measurement will start from the beginning of the first second of
next hour after the <Start> keystroke, and then will be repeated also from the
first second of the following hour after elapsing the integration period if the
number of cycles is greater than one. Default value: Off.
Disabling the measurement period definition
The integration period can be set as infinite or can be defined together with the
Repetition Cycles number. The Integr. Period Inf parameter activates the
infinite integration period. In this case the signal will be averaged all the time until
the <Stop> keystroke.
If the Integr. Period Inf parameter is On, the Split Cycles position appears.
The Split Cycles position enables you to limit the number of logger files when
the measurement period is not defined. If you select the number instead of Inf
the logger splitting will be performed no more times than this number.
If the Integr. Period Inf parameter is Off, instead the Split Cycles position two additional positions appear:
Integration Period and Repetition Cycles.
Measurement period
The Integr. Period parameter (integration
period) defines the period during which the
signal is being measured (and for some
results integrated) and measured values
logged in the result file as
Summary Results. The integration period
can be set in the special screen, which is
opened with the ◄ / ► key.
