“Run Delay”: delay time for starting measurement can be set after pressing key. If
0s is chosen, is the measurement will start right away.
Note
：
Though some certain trigger mode is chosen, you can still start measurement by
pressing key while on “1.Meas”submenu interface.
When choose “Equivalent interval”, the instrument displays as follows:
“Delta_T”: interval time for each starting measurement, which can be set between 1min,
5min, 10min, 20min, 30min and 1hour. For example “5 min” means starting at every 5
minutes.
Note: when Ts is longer than this interval, the actual measurement time is according to
Ts and the starting time will be delayed.
“Value”: the preset limit value. If the value is being exceeded, the instrument will start
measuring. The value can be set between 40 ~140.
“Delay”: the continuous limit-surpassing time. The instrument starts measurement
when the time-weighted average index SPL for analysis of channel 0 surpasses the
limit. The measurement will continue when the accumulated limit-surpassing time
exceeds the “Delay” value, otherwise it will stop. The value can be set from 0 to 999s.
When choose “Limit”, the instrument displays as follows:
When choose “serial”, the display shows as follows:
6.5.1.3 Equivalent interval activation
6.5.1.4 Limit-surpassing start
6.5.1.5 Serial measurement
