3. Charging battery
The MD-5075x uses a rechargeable LiFePO4 12 V - 6000 mAh.
At the end of battery useful life, the battery must be recycled or
disposed of properly, in order to protect the environment.

adapter).
•
The charging indicator ( ) will turn on red and will
remain that way until the battery is totally charged. Then the light will
remain green and keep in that way until the
MD-5075x is disconnected
of the mains.

source is connected, during one second.
Steady red light Battery under charge.
Flashing red light The battery was not successfully charged. It
denotes some trouble in the battery charging
process.
Steady green light The charge has successfully finished. The battery
is OK.
The rechargeable battery does not have “memory effect” and there are no
restrictions to start charging it as many times as is needed. However the battery
could be damaged if remains in deep discharge for a while.
To avoid this effect, charge the battery before left the equipment in storage and
don’t let pass more than 30 days without recharge, even if the instrument wasn’t
used (under storage, the battery loses part of its charge).
IMPORTANT : while the equipment is connected to the mains supply the START
key is inhibited, so you will not be able to make measurements.
