2. with the MRU battery charger (provided)
External equipment may only be connected while the analyzer is

6.3. Measuring with grid power supply / Battery charging
Whenever you connect the base unit with external power supply
(100..240 V / 50/ 60Hz ) the battery of the base unit will be charged.
The battery of the Remote Control Unit (RCU) will be charged, if the
RCU is in the charging frame of the mains connected base unit. The bat-
tery status screen will appear when the base unit is connected to the
battery charger and the RCU is in its charging doc. This screen can also
be manually opened with the menu button.
At the moment, if the battery is fully charged and the trickle charge
mode begins an acoustic feedback will be played.
6.4. Battery charge condition

charge condition.
Approximately 15 minutes (depending on the analyzer configuration)
before the battery is drained, the battery symbol (base unit or RCU) will
start to blink red (about once per second).
If the battery is almost drained and the analyzer is not connected to the
battery charger within one minute, then the analyzer will switch off au-
tomatically to prevent deep discharge of the battery.
