Power supply of Multilogger
The Multilogger is powered from three AA batteries and optionally also from
an ex5 V DC power supply, which can be also used for charging the
batteries. A simplified schematics of the internal supply circuits is showed in
Appendix 2.
External power supply _____________________________

External power supply can be connected to the Multilogger in
several ways:
a) to the power supply connector on the bottom of
Multilogger (for example, AC adapter included in basic
accessories)
b) to the terminal block of the RS232 interface (+5 V and
GND terminals)
c) via USB cable connected to PC (it will work only if the
USB port of the PC has current sufficiency to power the
Multilogger)

No energy from the batteries is discharged if external source is
present.

The Ethernet interface works only if an external power source is
connected. Some limited functions of this interface may also be
available during battery operation.
ATTENTION - never connect voltage greater than 5.5 V
to the external power supply input - it could damage the
device.
Batteries _______________________________________

The new Multilogger is equipped with high-quality NiMH
rechargeable batteries; the device is preset to intelligent algorithm
to their continuous charging if external power is present.
ATTENTION - if you insert the non-rechargeable batteries
to the Multilogger, change the battery model to Alkaline in
the device configuration. Never charge batteries that are
not rechargeabled!

Charging batteries:
a) batteries can be charged if an external power source is
connected
