If the Multilogger is not equipped with an internal pressure sensor,
you have to enter this value using the SW in the device configuration,
item
General - Preferences. You can enter either the current
pressure value at the given location (without conversion to the sea
level) or the current altitude.
How to set the Multilogger for measuring the difference of
two temperatures
________________________________
To do that, use the calculated measured quantity ( Calculated ). First of
all, select input quantities that will be used in the calculation formula.
Next, set the other items analogically to the other measured
quantities. I addition to the calculating of difference, other simple
mathematical operations are possible.
System alarms and how to work with them _____________
System alarms are used for diagnostic functions of the device and
probes connected to it. A system alarm signals a malfunction or
damage of the Multilogger or its probe. Unlike the alarms from
measured quantities which signal the problem of the technology that
the Multilogger monitors. A system alarm can be reported to a
different person than alarms from the measured quantities.
What is the inversion setup of the ALARM OUT output ___
By default, the ALARM OUT output is set in a way that its output
transistor is switched on during alarm state. For better security, this
output can operate inversely, i.e. the transistor is switched on when
there is no alarm and switched off during alarm state. In this case,
disconnecting a cable, turning the device off, etc. represent an alarm.
Backup and restore of device configuration ____________
If you have set the whole system and you need to back up its setting
with the possibility to upload it to the same or even different
Multilogger, download recorded data from device. The saved file
contains complete configuration of the Multilogger, which you can
upload back to the device.
