5. Operation and Maintenance
5.1 DRV3 Lite Parameters
The DRV3 Lite parameters are set using an external application such as the DRV3 Lite
settings via the USB or Bluetooth connection. The following sections describe how to set up
the DRV3 Lite parameters.
5.2 Reading the Measurement Mode Screen
DRV3 Lite starts up in measurement mode by default. It simultaneously monitors the selected
frequencies in the mid-band and the LTE band, unless the DRV3 Lite was set up for single
band detection. When the tag detection feature is enabled and the DRV3 Lite detects the tag
in the frequency it is monitoring, the symbol speaker appears on the screen when the level
is superior to detection level.
The top portion of the screen displays the following information from left to right:
Volume
Displays if the reference volume level for audible alert is On (
m
) or Off (
m
) when leaks are
detected, which exceed the detection threshold criteria.
Button Feedback
Button Feedback is usefull to change of one fonction to another. See section 5.4. When the
multifunction button is pressed, the volume icon is replaced by a “click” counter button to
provide user feedback. If there is a Bluetooth or USB connection, button is disabled.
Bluetooth
Displays the status of the Bluetooth connection. When there is Bluetooth connectivity, the
icon appears in black. When there is no Bluetooth connectivity, the Bluetooth icon appears in
white with a black background.
USB
USB logo appears at the same location than Bluetooth logo. It displays the USB connectivity.
USB connection takes precedence over Bluetooth connection.
Pressure Test
Displays if the DRV3 Lite is in ‘‘pressure test’’ mode. In PT mode, readings are shown in white
on a black background.
Battery
Displays the battery charge level. If there is no battery status icon displayed, this indicates
that the battery pack is charged. The battery icon is displayed only when the battery level is
low, in charge or defect.
5.3 Mute Volume during Normal Use
The DRV3 Lite emits an audible tone to help you locate the leakage source. The tone
increases with signal strength. You can enable or disable the audio functionality by pressing
once on the multifunction button.
5.4 Switching Mode
The DRV3 Lite can operate in three modes: system mode using the DSG1 signal generator,
“pressure test” mode using the portable DSG1 Lite signal generator. You can toggle between
those modes by pressing twice on the multifunction (on/ off) button. The third mode is
“spectrum mode” for on-the-spot spectrum analysis. To activate this mode press the button
four times.
