Application notes
Operation with permanently connected USB cable
_______
Datalogger is primarily intended to be operated as an autonomous unit
powered by its built-in batteries. Nevertheless, you can also operate it
with permanently connected USB cable.
In this case the device is not
protected against dust and water ingress, and, consequently, it cannot
be operated in locations in which such ingress protection is required.
Models with CO
2
concentration sensors include Li-Ion accupack that
can be charged from a PC or an external charger. The
datalogger’s
internal charging circuitry controls the battery charging process based
on its instantaneous condition, thus protecting it against damage.
The charging process will run only if
the device’s internal temperature
ranges between 0
°C and 40 °C. If this is not the case, the battery
will not charge even if the charger is connected. Other models
equipped with a primary lithium battery cannot be charged.
Device switching on and off
_________________________
If you switch on and off the device frequently, then its keypad and both
functions, i.e. device switching on and off from the keypad, must be
enabled in the device settings. Another option is to set the date
and time when you want the device to turn itself on automatically. Once
reached, it will be permanently switched on. For binary input
dataloggers, it is possible to control the recording on and off by
the level at this input (voltage or contact).
Measuring calculated humidity values
_________________
From among the calculated humidity values the device can provide
the dew-point temperature only. Other relevant calculated humidity
values can be obtained by subsequent data processing in the SW.
What is the purpose of the system alarms and how to work
with them
_______________________________________
System alarms are useful for performing the functionality diagnosis of
the device and of the probes connected to it. A system alarm notifies
of a failure or damage of the device or of its probe. On the contrary,
alarms on measurement values indicate a failure of the technology
the device is monitoring.
