6.1 Preparation for each measurement
6.1.1 Power supply
The measuring instrument can be operated optionally:
ywith the built in Lithium-Ion battery
ywith the included battery charger connected to the USB port
ywith USB cable on PC
6.1.2 Measuring with grid power supply / Battery charging
yThe device can be charged by connecting the supplied charger 90...260
V / 50/ 60Hz to the USB port.
yThe device can be operated while it is charged.
yThe device will switch to trickle charge mode once the battery is fully
charged.
6.1.3 Battery charge condition
The battery symbol indicates the battery capac-
ity. The battery symbol will start to ash every
second in red once the battery reaches a remain-
ing operation time of +/- 60 minutes (depending
on device conguration). The device will shut
down if the batteries are not charged in time to
prevent a total battery discharge..
6.1.4 Operating temperature
The device will display should you try and operate it whilst outside of the
dened temperature ranges..
NOTE
In case the device was stored at a very cold location you will have to give
the device time to adapt to the warmer environment before powering it
up, this will avoid condensation!
The device is not operable when not within the temperature parameters.
After powering up the device will give acoustic signals during warm up.

7 Maintenance and care
7.1 Maintenance
An annual service check and if necessary adjustment of the sensors at an
MRU service department www.mru.eu are recommended for the preser-
vation of value.
7.2 Care
The Analyzer needs only low maintenance eort for long value preserva-
tion
If the analyzer is not being used over a period it is recommended to
charge the battery before storing it and then recharge the battery every
