4.1 SELECTION OF MEASUREMENT PARAMETERS - MEASUREMENT SETUP
The Measurement Setup list consists of the
following parameters: the delay of start of the
measurements (Start Delay), the integration
period / measurement run time (Int. Period),
the repetition of the measurement cycles
(Cycles Number) and logging period
(Logger Step).
Time delay before the start of measurements
The Start Delay parameter defines the delay period from the moment the
<Start> key is pressed to the start of the actual measurement (the digital filters
of the instrument constantly analyse the input signal even when the
measurement is stopped). This delay period can be set from 0 second to
60 seconds.
Note: The minimum delay period is equal to 0 second. In the Calibration mode, the delay period is
always equal to 5 seconds.
Integration period
The Int. Period parameter defines the period during which the signal is being
measured. The definitions of the measurement results in which the integration
period is used is given in App. D.
The required value of this parameter can be set in the range of:
- from 1 s to 59 s (with 1 second or 10 seconds step),
- from 1 m (min) to 59 m (with 1 minute or 10 minutes step),
- from 1 h to 24 h (with 1 hour or 10 hours step).
It is also possible to set Inf value. The Inf value denotes the infinite integration of the measurements (until the
<Start/Stop> key is pressed again or after receiving the remote control code).
Additionally, the predefined periods: 1 m, 5 m, 15 m, 1 h, 8 h, 24 h and Inf, which are enumerated in the
standards, are also available (by pressing the ◄ key or ◄ with <Shift>; these values are placed in the sequence
mentioned above on the left in relation to 1 s).
Note: In the case of switching on the Auto Save function, the minimum value of the integration
period should be equal to or longer than 10 seconds.
If the user wants to switch on Auto Save option (path: <Menu> / File / Save
Options / Auto Save) the integration period value has to be equal or greater than
10 seconds. When Auto Save option was switched on and new entered
integration period value is less than 10 seconds, Auto Save option switches off
and the warning message appears on the display.
Number of repetition of measurement cycles
The Cycles Number parameter defines the number of cycles (with the
measurement period defined by Int. Period) to be performed by the instrument.
The Cycles Number number values are within the limits [1, 1000].
The Inf value denotes the infinite repetition of the measurements (until pressing
the <Start/Stop> key or after receiving the remote control code).
