[Overview]
UNOKIT is the official calibration tool for the UNO Sensor (multi-in-one air quality detector)
devices. It allows for the calibration of sensor module readings on the test UNO Sensor device
by comparing them with the readings of the UNO Sensor benchmark, ensuring the accuracy
of the sensor readings.
The UNOKIT supports the following models of UNO Sensor devices: UNOnext series and
UNOlite series. The sensor modules can be calibrated are listed.
⚫Carbon Dioxide (CO2)
⚫Particulate Matter (PM1/PM2.5/PM10)
⚫Total Volatile Organic Compounds (TVOC)
⚫Carbon Monoxide (CO)
⚫Formaldehyde (HCHO)
* The calibration of the test device will be performed based on the sensor combination of the benchmark, typically
UNO-9SW, which includes carbon dioxide (CO2), particulate matter (PM2.5/PM10), total volatile organic
compounds (TVOC), carbon monoxide (CO), and suspended, formaldehyde (HCHO).
* After calibration, sensor readings of the test device will be within the valid range of sensor readings of the
benchmark but may not be identical totally.

* The power cord is recommended to be stored inside the calibration chamber when not in use.
* The safety clasp can be used to quickly detach terminal connectors.
* There are two sets of terminal cables for both benchmark and the test device. The 14-pin cable is for use with
the UNOnext series (L), while the 5-pin cable is for use with the UNOlite series (M).

[Installation Guide]
1. Counter-clockwise release the safety clasp and open the calibration chamber.
2. Ensure all dip switches on the Benchmark are down, then install it on the left and the test device (DUT) on
the right. Connect the UNOnext with the 14-pin cable and the UNOlite with the 5-pin cable. Close the
chamber to complete the installation.
All dips of benchmark need
to be pulled down.

3. Connect the power cord, and then connect the USB mouse. * Please prepare your own USB mouse.
4. Power on.
* The benchmark does not need to be removed after installation unless there is a need for replacement.
* After installing the benchmark, please go to [System Settings] and update the [Time Zone] and [Benchmark
Calibration Date] for the first-time use.

[Calibration Process]
1. Follow the installation guide to set up the benchmark, test device and mouse and power UNOKIT on. After
the system starts up, the UNOKIT status will display 'Standby,' and the serial numbers of the benchmark and
test device and sensor readings of mounted sensors should both be displayed correctly. * If there is an error
message, please follow the instructions.
2. For the first-time use or when replacing the standard machine, please set the [Benchmark Calibration Date]
according to the benchmark information.
1. Choose Date
2. Click to Update

3. After the sensor readings mounted on benchmark and test device are displayed (not --), click on [Calibrate],
and UNOKIT will start the calibration process.
UNOKIT will perform the following actions: [Warmup] →[Analyze] →[Calibrate] →[Finish]. The message
block will also be keeping update according to the progress.
Note: If the sensor readings persistently do not display, it may indicate that the benchmark or test device lacks
this module, or the module is malfunctioning.
4. When the calibration process is finished, the UNOKIT status will display [Finish], and the information for the
benchmark and test device will be updated to their final states. At this point, the report has been generated.

9
5. If any errors occur during the process, the message block will display a red warning. Please follow the
message instructions to resolve the issue, then click [Reset] / [Next] or reboot UNOKIT.
Note: In some case, errors are discovered after [Finish] stage, a fail-calibration report also be generated.
6. After calibrating the test machine, you can refer to the [Installation Guide] to replace it with the next one and
click [Reset] or [Next]. Then, repeat steps 1 to 4 for a new round of calibration. Or refer to [Retrieve Report]
to get report. * No need to restart UNOKIT power after replacing the next test device.
7. After completing all calibrations and retrieving the reports following the next section, please remove the test
device, turn off the power, and store the power cord.

[Retrieve Report]
1. Click on [Open Report Folder ...], and the screen will display the report storage directory. All calibration
reports are PDF file, the filename format is [Calibration Date]_[SN of Test Device]_[PASSED/FAILED].pdf . e.g.,
20231215_2321L0170099_PASSED.pdf.
2. Insert the USB flash disk into [USB DISK], and the LCD will display a permission allow window. Select [Open
File Manager], click [OK], and the USB flash disk directory will appear.

3. Move the PDF file from the report directory to the USB flash disk directory. Select the PDF file, right-click,
choose [Cut], and then go to the flash disk directory, right-click, and select [Paste].
4. Click the [Eject USB Drive] button and eject the USB flash disk.
