12.2.2 Electric Power Supply
The instrument possesses a rechargeable nickel metal hydride battery. In principle only the
provided charger may be used for charging the MSI EM200-E. The sensors of the instrument
need continuous power supply (as well if the instrument is switched off). Charge after every
use of the measuring device.
The charge condition of the battery is checked by the instrument and displayed. When the
voltage and the capacity of the battery is too low, this is indicated by red flashing of the LED
on the top of the instrument. The battery should be charged immediately.
The charging lasts 1 to 4 hours, depending on the charge condition. During charging the
LED on top of the instrument is lit red. At the beginning of the charging a green flashing of
the LED indicates that battery and charging system is checked. After finishing of the charg-
ing the red light of the LED changes to green. That means the battery gets only conservation
charge.
If the charging circuit has an error detected, the LED will flash green and red together.
Please note, that the measuring instrument may be charged only at ambient temperatures
between + 5 °C and + 35 °C. Do not charge or store the instrument in the sun.
Change battery only with an original MSI spare part.
If the charging has been forgotten, the instrument will been shut off automatically. If it is
impossible to switch on the MSI EM200-E, because of low voltage, plug in the charger and
switch on the instrument again!!
