Application notes
Operation with a constantly connected charger
__________
Datalogger is primarily intended to be operated as an autonomous unit
powered by its built-in batteries. Nevertheless, you can also operate it
with a charger which is constantly connected to it, or with a computer.
The datalogger’s internal charging circuitry controls the battery
charging process based on its instantaneous condition, thus protecting
it against damage. In the case that a cable is connected to the USB
connector, 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. The internal charging circuitry initiates
the battery charging only when 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.
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. A system alarm may be intended for e.g.
another person than that receiving measurement value alarms.
