The duration of the Back Erase can be set to between 1 and 30 seconds using the
menu and can also be configured in the NoiseTools software. If the Pause function is
disabled, the Back Erase function is also disabled.
Memory
The
optimus
has a 4GB memory as standard. This is partitioned into two sections, one
to record time history and one for audio (VoiceTags and audio recordings). The space
allocated to each can be configured in NoiseTools.
The free space in the memory is shown in the General View as days or hours available
for both time history and audio. When either partition is full, the
optimus
will
overwrite the oldest data in that partition.
To clear the memory and permanently delete all stored data, choose the ‘Clear
Memory’ Menu page and follow the instructions on screen. Before permanently
erasing the data, you will be asked to press ‘OK’ to confirm.
Restore Factory Settings
This is in the Advanced Options Menu, and restores the
optimus
to the default options
for all user-definable settings in the Menus, and clears the calibration offset. For
settings such as ‘language’ where there is no default, the
optimus
will return to the
option it was shipped with.
Follow the instructions on the screeen, and press ‘OK’ to confirm.
This does not delete any stored measurements.
Windshield
The
optimus
can be used with a UA:237 90mm foam windshield which will reduce the
noise levels generated by air turbulence over the microphone capsule.
It can also help protect the microphone capsule from dust and fluids which can affect
the performance of the instrument.
