5 Initial Startup
The instrument must first be supplied with power. The instrument
is powered by the rechargeable battery pack included in the
scope of delivery.
The rechargeable battery packis equipped with a patented, con-
tact-protected module socket, which makes replacement possi-
ble without interrupting the measuring circuit.
5.1 Battery Pack
A quick-change, rechargeable lithium polymer battery (Z270A/
Z270G) with matching USB power pack, as well as a USB cable
(micro USB / type B), are included with the instrument.
Attention!
!
Observe safety information regarding the battery pack
(see section 1 on page 5)!
For initial startup, first charge the battery pack and then insert it
into the instrument.
The battery pack is subject to self-discharging at a rate of roughly
25% per year.
Note
Removing the Battery Pack during Periods of Non-Use
The integrated quartz movement draws power from the
battery pack even when the instrument is switched off.
It’s advisable to remove the battery pack before long peri-
ods of non-use for this reason (e.g. vacation). This pre-
vents excessive depletion, which may result in damage to
the lithium-ion batteries under unfavorable conditions.
