Controls on the probe display unit
On the display of the probe handle similar information as on the main display is
shown.
The currently detected leak rate is indicated as a bar graph. In a second line the
numerical leak rate (in the same unit of measurement as on the main display) is
shown. In the third line the type of gas equivalent is stated (e.g. He or R134a).
For Protec P3000XL only:
If the Protec P3000XL is operated in
HIGH
FLOW
mode, the gas equivalent is
displayed in inverted characters (on dark background).

background reading is set to ZERO. For details on the ZERO function please refer to
The right probe button is used for navigation when working in I•Guide mode (see
