3.9.3. Trigger
The Trigger tab enables the user to set up the device to record at predetermined times. A number of parameters are
interdependent and the user should be aware of this when setting up advanced trigger options.
There are two triggers
– 1 and 2, they operate independently but their effect is combined to control the record times. These
two triggers can operate independently or together with Alarms and the Button.
The triggers are used to start (and stop) the recording at user settable times. The Trigger needs to be enabled in order to
function. The recorded data is determined by the start time, the stop time and the sample rate. The user can select a start
time and stop time which will determine the number of samples recorded, or the number of samples can be set which will
determine the stop time. These are affected by the sample rate. In the event that the device is set to record on alarm, the
alarm check can be set to be continuous or to be gated by the trigger time. The Trigger can be set to record on specific days
of the week by checking the corresponding boxes. For example if a start and stop time is set and Monday, Wednesday and
Friday are checked, the unit will record at the start time and end at the stop time on each of the days checked. In addition
the button can be set to stop and start recording provided the triggers are not active
– if the device is recording because of a
trigger being active the button cannot stop that recording even though it is enabled.
There are two other things to take into account
– Cyclic Mode Enable essentially allows the device to record forever – or at
least until the battery dies. It allows the device to overwrite old data when the memory fills up. When the device gets to the
end of memory, it cycles around and starts at the beginning again, overwriting data. You will always have the latest samples
in memory
– If this box is not checked the device will stop recording when memory is full. Fill Memory if checked will force
the device to record until memory is filled. Basically it disables the stop time limitation and forces the number of samples to
the maximum.
3.9.3.1. Start Time
This is set to be the time the recording will start. If stop time is not enabled the device will record until memory is filled
or if cyclic mode is enabled it will record until stopped by the user (or the battery dies)
3.9.3.2. Stop Time
This needs to be enabled in order to be active. The user
needs to set a stop time which is greater than the start time.
The stop time can be set as a date and time and the software
will calculate how many samples this will record. The stop
time needs to be applied using the “Apply” button.
Alternatively the user can set the number of samples to be recorded and the software will calculate the stop time.
