5.4 Using the Nardalert S3 as an area monitor
The NS3 should be fully charged and configured for your personal use.
The factory provides both a lanyard attachment and a belt clip for your
convenience, and a silicon skin to help provide protection for the unit
against shock.
Once you have verified the proper mounting configuration and have
charged the unit you should verify that the alarm levels shown on the
second start-up screen meet with your company's policy. The NS3 was
designed to be mounted with the reverse side towards your body. Some
customers prefer to wear the unit mounted to a waist belt while others
prefer a lanyard attachment. Either method of attachment is acceptable
as long as the unit is normally kept close to the body to improve the
radial field sensor's performance.
The default setting for the LCD backlight is to extinguish after 10
seconds, in order to save battery life. You can depress any button to
activate the LCD backlight, but the display should be visible in direct
sunlight without the backlight. An LED will briefly flash every 10 seconds
to indicate the unit is operating properly.
The NS3 samples the sensor's output approximately every 32 msec.,
and uses the average of 8 samples to log at its fastest rate. The display
is updated every second, so the level displayed is an average of the four
logs. The monitor can be set to log at a rate as fast as 4 times per
second for high speed situations.
