GENERAL
dV-2 has two operating keys. The left key (Select) serves to select the functions and
the pressure units. The right key (enter) activates the selected function or pressure
unit.
Turn-on: Pressing either key turns the instrument on. When pressing the right key
(enter), the dV-2 immediately indicates the actual pressure. When turning on with the
left key, the instrument first displays the software version (month/year), followed by
the full scale pressure range (in bar). When the instrument is turned on, an arrow is
pointing to the pressure unit in use. If the battery symbol ( ) lights up, the battery must
be replaced. A triangle with an exclamation mark ( ) indicates that the instrument
is in the continuous operation mode (if not, the instrument turns off 15 minutes after
the last key function).
Turn-off: Pressing the right key (enter) turns the instrument off.
