4.2.1.
Checking the battery charge status
If the battery charge level is low or a measurement takes a long time the power may turn off,
resulting in the measured data not being completely recorded. To avoid this ensure to verify
the battery charge status before starting a measurement.
The LED on the rechargeable battery enables the remaining battery level and battery
charge status to be verified.

* With the EMP-2 a fully-charged new battery supports about 5 hours of continuous
measurements.
Caution
*
The EMP-2 battery should not be used or left anywhere exposed to direct sunlight,
in a car exposed to the sun, close to a heater, or anywhere damp. Failure to
follow the above could damage it. The battery should also not be stored at
temperatures below 0°C or above 40°C.
*
At low temperatures the performance of the battery could drop. The battery
should be used within the operating temperature limits (0 to 40
°C
).
*
The battery is a consumable item that deteriorates depending on the frequency of
use and storage place used. When the serviceable time of the battery after being
charged has dropped or does not work the battery life has expired and hence
should be replaced.
4.2.2.
Checking the SD card
The EMP-2 stores all measurement result data on an SD card. No SD card being in place or
with its erasure prevention switch locked will result in the measurement results not being
savable. Before starting a measurement verify that the SD card is unlocked and that it has
sufficient free space before inserting it into the equipment.
