Commissioning
The instrument is supplied with a basic con-
figuration. These values can be altered using
the Set and Option modes to suit your own
personal requirements.
Your SHERPA is always switched on. After
using the SPEED-mode or the TEMP-mode
the user should switch manually either to the
ALTI-mode or to the BARO-Mode. The battery
life of the SHERPA will last up to one year, if
the user follows the above procedure.
The user should be aware that the instrument
absorbs a greater amount of battery power
if it remains in either the SPEED-mode
or TEMP-mode. However, the instrument
switches automatically to the BARO-mode,
after approximately 15 minutes.
Battery compartment
Your SHERPA is powered by a lithium battery
(3 V, CR2032). When battery power is low, the
message ‹BAT› appears in the display.
The instrument is always initialized with the
basic configuration when the battery is re-
placed. The barometer, the time and the alti-
meter all have to be reset.
A watertight membrane in the battery com-
partment serves to equalize pressure. If
your SHERPA is exposed to too much
humidity (e. g. if dropped into water or
exposed to heavy rain), this membrane must
be carefully dried without delay. Leave the
battery compartment open until the whole
instrument is dry again.
