Name
Explanation
①Power button
It is a button to turn the power on / off. Each time the button is pressed, the
status changes to ON and OFF.
②Measurement button
It is used for measurement.
③Status indicator
The status of MYIRO - 1 is displayed.
Indicates states such as measurable, scan success / failure, errors, etc. with
color and blinking.
④Network indicator
Indicates the connection status of the wireless LAN.
⑤Battery indicator
Indicates the battery status of the battery remaining capacity and charging.
⑥USB connection terminal
It is used to connect MYIRO-1 and PC with USB cable. Besides communication
with the PC, it is also used for charging.
⑦White calibration cap
It is used for calibration. When calibrating, attach it to the measurement
opening.
⑧Measurement opening
It is an opening for measuring the sample.
⑨Tripod screw hole
It is a screw for fixing a commercially available tripod. It is used for display
measurement.

3. Attaching / removing the ambient light attachment
Used for ambient light measurements.
How to install
1 You can install the ambient light
attachment by turning the ▲ mark in the
right figure in the direction of the arrow.
How to uninstall
2 You can uninstall the ambient light
attachment by turning the ▲ mark in the
right figure in the direction of the arrow.

4. Charging method
It charges by connecting to a PC or a commercially available USB-AC adapter with a USB cable.
The remaining amount and state of charge of the built-in lithium-ion battery are indicated by the battery
indicator as follows.

Explanation
Supplementary explanation
No light
Enough
battery
power
Built-in lithium-ion batteries have
sufficient power and can be
measured.
Approximately 670 scan
measurements are possible from
the fully charged state.
If you leave after turning on the
power, the power will run out in
about 2 hours.
Blinking(Dark
orange)
Low
battery
level
Battery level is low. Although you can
measure for a while, we recommend
charging.
Approximately more than 50
scanning measurements can be
done after flashing begins.
Lighting up(Dark
orange)
Charging
Battery is charging.
It will be fully charged in about 2
to 3 hours with the power off
status.
5. Power ON / OFF
Pushing the power button from the OFF state turns on the power.
Pushing the power button from the ON state turns off the power.
6. Auto power off function
MYIRO-1 has “auto power off” function, and when communication doesn’t operate for a certain period of time,
the power turns off automatically.
To turn on the power again, press the power button. At this time, the connection with the application is
disconnected and the calibration data is deleted, so it is necessary to reconnect with the application and
recalibrate.
7. Connecting to PC
Connection with PC has USB connection and wireless LAN connection.
When using USB connection, connect MYIRO-1 and PC with USB cable.
In the case of wireless LAN connection, connection work with the initial setting tool is necessary at first
connection. Please look at the instruction manual of the initial setting tool.
The second and subsequent times are automatically connected to the network under the conditions set above.
If both USB and wireless LAN are connected, priority is given to USB connection.
If you disconnect the USB cable, it will be connected via wireless LAN.

8. Calibration
There are the following types of calibrations, but in either case the work in MYIRO-1 is the same.
For Chart measurement
For Ambient light measurement
For Display measurement
Procedure
8－１ Attach the white calibration cap to the measurement opening.
Before mounting the cap）
How to attach) Align the line of the main body and the line of the calibration cap (hereinafter, gray line) and
rotate it in the direction of the arrow described on the calibration cap.

After mounting the cap）
Note:When not using the measuring instrument, keep it with the calibration cap attached to prevent dust
adhesion.
Reference) At the time of measurement, the calibration cap can be stored as shown below.

8－2White calibration is performed by measurement button or control from SDK.
When white calibration is performed, the status indicator changes as follows depending on the calibration
status.

In uncalibrated condition,
calibration is necessary to
measure.

Successful
calibration
The calibration was
completed correctly.
After that, the state

Calibration
failure
The calibration failed. It is
necessary to recalibration in
the correct way.
After that, it is
automatically
uncalibrated.
After successful calibration,
lights up(Blue).
Measurable
Measurement is possible.

9. Scanning measurement
Set the ruler on the chart so that the △ mark(Red arrow in the figure) of the ruler matches the left edge of the
chart.
Set MYIRO - 1 to the left edge of the ruler. The scan operation needs to start from the paper white part.
If you keep pushing the measurement button and the status indicator changes from blue to white, slide
MYIRO - 1 as it is. After measuring, release the button and the measurement is over. Please slide at a
constant speed as much as possible, in about 3 to 5 seconds from the edge of the ruler to the end.
Scanning is possible from the right or from the left. Regardless of which way you operate, the data will be
output from left to right.
When measuring, the status indicator changes as follows depending on the condition.

10. Spot measurement
Adjust the spot target of the ruler to the part to be measured.
Place the measurement opening of MYIRO-1 so that it meets the spot target, and perform measurement with
the measurement button or control from the SDK.
11. Ambient Light Measurement
With the ambient light attachment attached, perform measurement with the measurement button or control
from the SDK.
12. Display measurement
Attach a commercially available tripod to the tripod screw of MYIRO - 1 and set the MYIRO - 1 so that the
measurement opening faces the display to be measured at a distance of about 5 to 30 mm.
Measurement is performed by measurement button or control from SDK.
