Mahr GmbH, MarSurf PS1
3 Commissioning
The MarSurf PS1 is delivered with the power
supply isolated to ensure that the built­in battery
does not lose its charge if stored for a lengthy
period.
1. Move the reset switch (17) to the right into
the "I" position to make the instrument ready
for operation.
To prepare the power pack:
1. Select the appropriate mains adapter and in­
sert it into the power pack.
To charge the battery:
1. Connect the power pack to the "9 V ="
socket (18) on the MarSurf PS1 and plug it
into the mains socket.
During the charging process, the four bars
in the
symbol appear and disappear in
sequence.
Once the power pack has been connected,
measurements can be carried out immediately.
The battery capacity reached in % can be dis­
played at any time (see Section 3.3.1).
The battery will be fully charged after approx.
1 hour, and the instrument automatically
switches from rapid charge to trickle charge.
The MarSurf PS1 is also charged if it is connected
to a PC via its USB interface (15), but the battery
takes longer to charge using this method.
3.1 Charging the Battery
The MarSurf PS1 is powered by a built­in battery.
The power pack supplied can be used for
stationary operation.
The battery should be charged
– if the instrument is being commissioned for
the first time,
– if around 3 months have passed since the
battery was last charged,
– if the symbol is flashing (i.e. the battery
is down to around 15 % of its capacity),
– if no measurement is possible even though
the symbol is not flashing.

For charging, only use the power pack
supplied!
If other power packs are used, the
MarSurf PS1 may be damaged and any
warranty will be rendered null and void.

This can happen after long periods of storage, for exam­
ple.
