We recommend to use the Multilogger with NiMH accumulators;
specify the following device configuration:
•
NiMH accumulators (if they are installed).
•
Do not turn on the Energy saving mode. The Multilogger will
perform measurement with a fast sampling (1 second for all
quantities with the exception of CO
2
concentrations, which will be
measured every 2 minutes).
•
Switch on the display backlight as needed. If it is necessary to
make the measured values on the Multilogger well visible all the
time, turn the backlight on only when the device is powered from
an external power supply.
•
Use the optical alarm signalization using the LED diodes as
needed.
•
Set the audio alarm signalization as needed.
•
If you want to operate the Multilogger
“remotely”,
disable
“
Off key
”
on its keyboard ( Vision software, option General -Advanced
- Device start ). You will thus prevent unauthorized or unwanted
device turn-off by unqualified personnel. In these cases, it is also
advisable to limit access to the device configuration from the
keyboard using PIN codes.
•
If your LAN is backed up and works correctly during mains failure,
it is possible to send warning e-mails and records to
database (DataLink). See part

•
Attention - if you use an external audio unit powered from the
Multilogger, it will not work during external power supply failure!
For measuring of room temperature and humidity using the
Multilogger powered from an external power supply and with an
active Ethernet interface or charger, probes with cables are more
suitable. Short probes without cables (DigiS/M, DigiL/M or 200-80/M)
can be used but the measurement accuracy will worsen due to the
waste heat created by the Multilogger. The other sources of the waste
heat are there - battery charger or the display with backlight that is
permanently turned on (especially in the case of higher backlight
intensities). The measurement error can reach approxi1 °C
for the device installed on an inside wall without forced ventilation.
After an external power failure, when the device was running from the
batteries for a while, the batteries are automatically recharged by low
current as soon as the external power is restored.
