- time-limited (temporary) - if the alarm after the set time interval
is still current, the optical and/or acoustic signalling is activated
again. The time interval can be set in the device configuration
under the item "Reactivate muted alarm signalling".
By local keypad on the device only deactivate the optical and/or
acoustic signalling; Sign ALARM at the top of the display is displayed
for the whole time of the alarm condition.
Alarm events - Memory occupancy
___________________
Use this panel setting, if an overrun of the pre-set limit value of the data
memory occupancy needs to be signalled. The signalling mode may
be selected optionally as optical (by means of a LED diode)
or acoustical.
Alarm events - System failure
_______________________
These panel choices make it possible to set the so-called system
alarms, which indicate some technical failure of the datalogger or of
some of the probes connected to it. The signalling mode may be
selected optionally as optical (every time by means of a red LED diode)
or acoustical.
The device can respond to the following conditions:
a)
Measurement error on any channel
...... e. g. a probe has been
disconnected or broken.
b)
Device configuration error
…... the device configuration has
been disturbed unexpectedly.
c)
External power failure
…..
the USB connector of the device
can be permanently connected to external power (USB
charger or computer). This state can therefore be used as
an external power failure indicator.
d)
Low battery
…. it informs that it is necessary to connect
external power and charge the internal battery, see chapter
“
Running the device - Charging the batteries
”.
e)
Time setting error or battery is
discharged
…. the battery has
run out of charge.
