5. Requirements for test assemblies with the LPC 200
Battery level
Before starting any task, the device should be switched on
briefly to determine that there is sufficient charge in the
battery (battery level in %).
The battery level is indicated top right at the display in a
device-status message.
100 % battery charge will allow approximately 25 hours of
instrument operation.
Initially the test assembly must be mechanically constructed and, if necessary,
electrically connected (both in accordance with the previous Chapters).
Before switching the LPC 200 on, it should be ensured that the test assembly
is not pressurised (System is vented to atmosphere) and that the equipment is
correctly assembled (correct mounting position).
In particular, assemblies with small measuring ranges
(e.g. < 1 bar) are orientation dependent (i.e. the mounting
position influences the measured signal considerably). This
can be compensated, if necessary, using the Tare function (see
Chapter 6.5 "TARE-Function").
Absolute-pressure measuring ranges < 1 bar are, by definition,
in an overload condition at atmospheric pressure. Therefore
no measured value appears in the display, but rather 3 cross-
es, indicating a pressure outside of the measuring range of
the attached sensor. If the pressure is reduced, so that it falls
within the permissible measuring range, then the measured
value appears in the display.
