Welcome
Thank you for choosing CloudMinds’s AI Raman spectrometer Lingxi MR-5S. This
handbook will help you understand the initial settings and basic functionality of the
Lingxi MR-5S as well as necessary safety information.
Before reading the contents of this manual, please note:
The functions described in this manual are those featured on your device as it
is now. If the descriptions do not match your device’s actual functions due to
software or hardware changes, then please use the functions as they actually are
on your device.
Warning
Before opening the box, check that the external packaging is intact.
Do not use the laser functions of this device if you have not received
formal training.
The laser diode of this device is a component of the Raman
spectrometer. It can produce lasers with a power between 100 to 500mW
and a 785nm long wavelength. The laser uses its own lens to focus on a
spot 10mm away.
This device uses a Class 3B laser.
Exposing human eyes or skin to the laser emitter window can cause
injury. The safety distance for this laser is no less than 50cm from the laser
emitter window.
Within the 50cm safety zone, use a management controller, work
controller and/or laser safety goggles to protect the operator's eyes.
Do not disassemble this device by yourself, including but not limited to
its protective case and battery. If disassembly is required, contact an

2
authorized service center.
Do not use controllers, modulators or software applications that are not
compatible with this device to control this device.
Comply with your organization's safety protocols and rules when using
this device’s Raman laser to detect unknown substances. Using the
smallest possible samples and lowest laser power can help avoid potential
hazards.
Do not detect heat-sensitive materials in closed containers. Doing so
can increase pressure inside the container and lead to the container
exploding.
The Lingxi MR-5S is not an intrinsically safe device. Users must take the
necessary safety precautions when using this device.

Attaching detection probes
Your device is equipped with two detection probes. Attach and remove the
device’s detection probes in a clean, dry environment. Prevent dust, pollutants,
water or other liquids from entering the device, which can cause electrical faults or
influence the results of the laser detection.
If the solid/power detector cap, reagent bottle holder or self-verifying calibration cap is
attached to the top of the device, remove it first.

The distance between the center of the laser lens and the laser focal spot is
approximately 10mm.
Connecting to a network
This device can conduct online detection via mobile networks and wireless local area
networks. It can also be used offline.
Connecting to a mobile network
If you have inserted a SIM card into the device, you may choose to use a mobile
network to connect to the cloud detection service.
Connecting to a wireless local area network
1. Swipe down from the top of the screen to open the notification panel. Tap and hold
WLAN to go to the wireless local area network settings page.
2. Select the network you would like to join from the WLAN list.
3. Depending on the network:
• If the network is not password protected, the device will connect
automatically.
• If the network is password protected, enter the password and tap .
Disconnecting from a network
Your device will disconnect from the network in the follow situations:
• When there is no available network.
• When the flight mode is enabled: Swipe down from the top of the screen to open
the notification panel, and then tap Airplane node.
When offline, the device will automatically use the offline detection mode to detect
samples and use the local database for comparison.

Do not shine the laser onto eyes or skin.
Do not test black, brown or dark-colored substances. When these
substances absorb the energy of the laser, they can become hot or start to
burn, resulting in fire.
Do not place the substance to be identified on paper for testing. The
paper may absorb the energy of the laser and become too hot or even start
to burn, resulting in fire.
If the substance to be identified is light in color, any dark spots in the
substance absorb the energy of the laser more easily and quickly heat up.
If you have not determined if the substance to be identified has heat sensitive
properties, prepare in the following way:
• Place a small amount of the substance to be identified (<300µl or 5 drops for
liquids, <300mg for solids) into a reagent bottle or bag.
• Do not seal the container.
• Do not place the substance to be identified on paper or other cellulose materials
for testing.
• Set a detection countdown.
• Reduce the laser power to a low level.
• The safe use zone for this device is 50cm.
• Keep the laser emitter window at least an arm's length from people's eyes.
Online detection
If the device is logged in to a cloud detection service account, online detection can be
carried out while connected to a network. When carrying out online detection, the
device calls the cloud database to compare substances and return results.
1. In the detection domain, tap Analysis.
2. If the sample to be identified could be a flammable or explosive substance, when
setting the detection countdown, the length of the countdown should depend on
the time it takes people to move a suitable distance away. When a countdown is
not necessary or a countdown has been set, line the laser emitter window up with
the substance to be identified or its container, and then tap Analysis.
3. After the required time (the detection time depends on the nature of the sample),
the device shows one of the following types of results.

Check that the laser focal spot is on the substance to be identified and
not in the air. Otherwise, this sample may not produce a Raman signal or the
signal may be too weak to measure.
Offline detection
Your device may only use offline detection in the following circumstances:
• The device is logged in to an account, and you have manually chosen offline
detection.
• The device is logged in to an account, but the network connection has been lost.
• The device is not logged in to an account.
Offline detection uses the spectral database on your device to compare detection
results. The results will be temporarily saved to the device only. To upload the results
to the cloud, re-connect the device to the network.
The offline detection results will be handled in different ways depending on the
situation:
• The device is logged in to an account, and you have chosen offline detection: The
results will be saved to the device. When you switch to online detection, the offline
detection results will be automatically uploaded to the cloud.
• The device is logged in to an account, but you lost your network connection and
were automatically switched to the offline detection mode: When the network
connection is restored, the detection results will be automatically uploaded to the
cloud.
