Select Hourly, Daily or Weekly cycle (or No Secondary Cycle to disable it). Then select the threshold to
apply during the secondary cycle. Finally select when the secondary cycle begins and when it ends.
The Start and End of the secondary cycle are defined by:
•
A Start minute and Stop minute for an hourly cycle
•
A Start hour/minute and Stop hour/minute for a daily cycle
•
A Start day/hour/minute and Stop day/hour/minute for a weekly cycle
When the instrument time is between the Start and Stop times, the secondary threshold is applied.
Otherwise, the primary threshold is applied. That secondary threshold can be lower than the primary
(for instance for a more sensitive setting at night). It can also be higher. In order to disable alarms
during certain time periods, use a very high threshold, such as 200 dB.
Note:
In order for the secondary threshold to be applied, the instrument time must be set. So after a
reset of the instrument, and before the time is set by running the Instrument Manager, or the instrument
connecting to a server, the secondary threshold cycle will not be in effect, even if it was programmed.
This is because any secondary threshold is based on the instrument internal time, and that cannot
operate properly until the proper time is set.

WiFi™
Battery Drain
Connecting to a network drains the battery. Even if the instrument is idle, if the periodic connection is
enabled, the instrument will regularly wake up and attempt to connect to the server. Trying to connect
at regular intervals will drain the battery in a short amount of time.
When that behavior is unwanted (for instance when the instrument is unused and in storage) pressing
the
Disable All
button (see 4
) will completely disable
WiFi™
and email connectivity. If the
instrument is idle with all its
WiFi™
connectivity disabled, it can keep its battery for at least 6 months.

Instrument_Listener Application
In order to report recorded data, and send alarm emails, the instrument must connect to a remote PC
(a server) that is running the
Instrument_Listener
application. The
Instrument_Listener_Installer_Vxxx
must be installed on the PC (
Vxxx
represents the version number of that application).
The remote PC (the server) must:
•
Be on
•
Be reachable over the network, either by an instrument on the local network, or on a global
network. In the case of a global network, all firewalls must allow the server to receive incoming
connections.
•
Be running the
Instrument_Listener
application. It may be useful to setup that application so
that it runs automatically when the PC boots.
The
Instrument_Listener
application (see
) always listens to incoming connection attempts
from instruments in the field. Whenever an instrument tries to connect, it opens an
NSRTW_Server
window (see
). That window briefly opens to show the communications with the instrument,
battery level and temperature. It manages all operations that the instrument needs to perform and then
closes back down.
