80 Maintenance
7.2 Testing and changing device batteries
7.2.1 Changing and connecting device batteries
DANGER!
Using the incorrect batteries may present a risk of explo-
sion!
Connect only the prescribed Elster battery-types to the device
(see chapter 9.1.4.
WARNING!
Misuse of batteries may present a risk of injury.
Special care must be taken when handling batteries.
Therefore:
– Do not throw the batteries into the fire or expose them to
high temperatures. There is a risk of explosion.
– Do not charge the batteries. There is a risk of explosion.
– Liquids that are produced as a result of misuse may lead to
skin irritation. Avoid all contact with liquids. In the event of
contact with the skin, rinse with plenty of water. If the liquid
enters the eyes, immediately rinse with water for 10
minutes and seek medical attention.
CAUTION!
Reduced battery power!
The simultaneous use of old and new batteries considerably
reduces battery power.
Therefore:
– You should always replace all batteries together.
The batteries can be exchanged without a calibration officer as the housing
does not need to be sealed.
In an as-delivered condition, two batteries are connected to
the base board of the EK280. To double the service life of the
batteries, two additional batteries can be connected.
You should always connect at least two batteries (to X10 and
X13 or X11 and X14) to the EK280. This way, the EK280 will
continue to work whilst the batteries are being changed.
