Any parameter in the Measurement list can be changed only when the
instrument is not currently executing a measurement. The parameters are
displayed with grey colour. The blinking „measurement” icon indicates that the
instrument is performing a measurement.
4.1 SETTING GENERAL MEASUREMENT PARAMETERS – GENERAL SETTINGS
The General Settings screen allows you to
configure general measurement parameters:
delay of the measurement start (Start Delay),
synchronisation with the instrument’s RTC
(Start Sync.), integration period/measurement
run time (Integration Period), repetition of
measurement cycles (Repetition Cycles),
RMS detector type (RMS Integration), 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. Default value:1s.
Synchronisation of measurement cycles
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.
Infinite integration period
The Integr. Period Inf parameter activates the infinite integration period. In this
case the additional Split Cycles parameter appears which define the maximum
number of splits of the data registration in separate files – see Chapter 4.4.1.
If the Split parameter (path: <Menu> / Measurement / Logging / Logger Setup)
if Off, the signal will be averaged all the time until the <Stop> keystroke.
If the Split parameter not Off, the signal will be averaged from the measurement
start till the split. After the split new measurement will start with averaging until
the next split. Such measurements will be performed as many times as is set by
the Split Cycles parameter.
If the Integr. Period Inf parameter is disabled, then two positions (Integration Period and Repetition Cycles)
become active.
