6.1 Battery Monitoring
Whilst in operation the state of the rechargeable
battery is checked. If the battery is really low, the
following message appears:
With the present level of charge further measure-
ments can still be made.
If the “batteries low” message appears, the
accumulators are depleted and must be charged up.
Changing batteries is not necessary as the device con-
tains 2 rechargeable batteries. Changing batteries is only required in the event of the bat-
teries having sustained damage.
As the batteries are monitored by an integrated charging regulator whilst charging and dis-
charging, exchanging the batteries is only to be expected at the end of their useful life
(which is several years).
Charging of the batteries is essentially carried out via the USB jack of the KMG.
3 charging modes are provided for in this connection:
a) The power pack included is fitted with a USB jack.
b) The measuring device is connected via the USB cable to an adaptor used for car ciga-
rette lighters
c) The KMG is charged whilst the USB is connected to a computer via the USB interface.
Charging Adaptor for Mains Operation (230V) and Car Power Supply (12V)
The shortest charging time is achieved using the plug-in power unit. If the batteries are flat,
the charging time is approx. 3 - 4 hours.
