Note:
- Due to interferences in the network or to high ambient temperature, the charging process of re-
chargeable batteries may finish prematurely. When charging time is too short, turn off the meter and
start charging again.

Message
Cause
Proceeding
Battery connection error!
Excessive voltage
at the rechargeable
batteries package
during charging.
Check the contacts of the re-
chargeable batteries package.
Should the problem persist, re-
place the package.
No battery!
No communication
with the controller
of rechargeable
batteries or batter-
ies compartment
put in.
Check the contacts of the re-
chargeable batteries package.
Should the problem persist, re-
place the package. Insert the re-
chargeable batteries instead of
batteries.
Temperature of recharge-
able batteries too low!
The ambient tem-
perature is lower
than 10C
It is not possible to charge the
rechargeable batteries correctly
in such a temperature. Place the
meter in a warm place and
commence the charging mode
anew.
The present message may be
displayed also in the case of
deep discharging of the re-
chargeable batteries. It is then
recommended to try to turn the
charger repeatedly.
Pre-charge error
A damaged or
deeply discharged
rechargeable bat-
teries package
The message is displayed for a
while and then the pre-charge
process begins again. If after
several attempts the meter dis-
plays the following message:
Battery temperature too high!
the the battery pack must be re-
placed.
Temperature of the re-
chargeable batteries pack
is too high!
Ambient tempera-
ture is higher than
od 35C
Move the meter to the environ-
ment with lower ambient temper-
ature, and the wait for its cooling.
6.4 General principles for using Ni-MH rechargeable batteries
- If you do not use the device for a prolonged period of time, then it is recommended to remove the
rechargeable batteries and store them separately.
Store the rechargeable batteries in a dry, cool and well ventilated place and protect them from direct
sunlight. The temperature of the environment in the case of prolonged storage should not exceed
30°C. If the rechargeable batteries are stored for a long time in a high temperature, then the occurring
chemical processes may reduce their lifetime.
- Rechargeable batteries NiMH usually lasts for 500-1000 charging cycles. These batteries reach
their maximum capacity after being formatted (2-3 charge/discharge cycles).
