1 RBRquartz³ Q
The RBRquartz3Q integrates the Paroscientific Digiquartz® pressure sensor forbest-in-classaccuracy and low drift
performance.
Intended for long-term autonomous or realtime observations of water level, tides and waves, the RBRquartz3Q can
resolve small changes over long deployments.Flexible measurement schedules and burst sampling permit
applications for tide, wave, and sea level measurements. The RBRquartz3Q has a large memory capacity, sufficient
power for extended deployments, and USB-C or Wi-Fi download for large data files.
The RBRquartz3 features:
High accuracy
Internal USB-C connector
Large memory
Quartz stability
For a detailed description of wave and tide measurements, seeRuskin User Guide: Standard Loggers3.

Power supply selection
If connected, an external power supply will be used preferentially over the internal batteriesas long as the voltage
remains 4.5V or greater. If it drops below 4.5V or complete disconnection occurs, the system automatically switches to
the internal batteries.
Clock
The instrument's clock is maintained during brief disconnections. This time is usually sufficient to change batteries or
replace desiccants.
USB-C power
The USB-C cable provides power sufficient for configuration or data download. However, the instrument requires an
internal or external power supply to perform sampling.

3.1 Opening and closing the instrument
.
Opening theinstrumentwith a standard end-cap
Twist the battery end-cap counterclockwise.
Once fully unscrewed, pull the end-cap away from
the housing.
.
Closing the instrument with a standard end-cap
Place the end-cap back on the instrument.
Twist the end-cap clockwise until aligned with
PAUSE.
Openinstrument with a standard end-cap
Opening theinstrumentwith a connectorised end-cap
Twist the battery end-cap counterclockwise.
Once fully unscrewed, pull the end-cap away from
the housing.
For instruments with connectorised end-caps,
unplug the umbilical cable.
.
Closing the instrument with a connectorised end-cap
Plug the mini-display port connector into the
instrument as shown.
Twist the end-cap counterclockwise two full
rotations to unwind the umbilical cable.
Place the end-cap back on the instrument.
Twist the end-cap clockwise until aligned with
PAUSE.
Open instrumentwith a connectorised end-cap
Remember to keep the O-ring clean and avoid scratching the O-ring mating surfaces. Carefully inspect the O-
ringbefore deploying the instrument.

3.2 RBRquartz³ Q interface
The RBRquartz³ Q instrument provides an internal USB-C port and, depending on the end-cap type, an
externalMCBH-6-MP connector.
.
.
USB-C connection
A USB-C desktop cable is supplied in the instrument support kit.Use this cable to downloaddata from the instrument
to your computer.Follow the steps below to access the USB-C port located inside the instrument body.
Remove the batteries.
Connect the computer to the instrument through the USB-Cport.
Start the Ruskin application.
Mini-display port
The mini-display port is located next to the USB-C port. This is the port to use for the umbilical cable from the
connectorised end-cap.
Left: mini-display port, right: USB-C port
Refer to Opening and closing the instrument for details on accessing connection ports.
Refer to Specifications for the external MCBH-6-MP connector pinout diagram.

End-cap types
RBR standard loggers are compatible with three different end-caps. These end-caps are interchangeable between
instruments.
Standard end-cap
Connectorised end-cap Right-angle connectorised end-cap
.
MCBH connectors
Only connectorised battery end-caps have the external MCBH-6-MP connector. Depending on your needs, they may be
wired to support the USB, RS-232, or RS-485 communication (selected at the time of order).
.
MCBH connectors
Patch cables and underwater extension cables are sold separately.

3.3 Orientation and datum location
The datum of theRBRquartz³ Q is located at the centre of the pressure sensor diaphragm. RBR performs an offset
adjustment with the sensor facing downwards, as shown in the first image.It is recommended to deploy the instrument
verticallyto match the way it was calibrated.It is acceptable to deploy horizontally if necessary.
Recommended orientation:
sensors facing down
Datum location
Avoid deploying the instrument vertically with the sensor facing up! Such orientation will affect performance
of the pressure sensor due to increased build-up of sediment.

3.4 Twist activation
Twist activation allows you to start or pause the instrument without the need to connect to a computer. All RBR
Generation3 standard loggers are equipped with twist activation as a standard feature. SeeRuskin User Guide: Standard
Loggers3.
When you select "Twist activation" in Ruskin, the instrument starts to sample based on the twist on/off position rather
than a schedule. To start sampling, first click "Enable" in Ruskin to enable logging. The status will then become
"Paused". Turn the battery end-cap to the RUN position. Theinstrument will vibrate with one long pulse and start
sampling. To pause it, turn the battery end-cap to the PAUSE position. Theinstrument will vibrate with three short
pulses to indicate it has stopped logging.
