When power is
not
turned on
Press and hold the power button for more than 3 seconds. A short
push will not power up.
Please make sure that 9V battery is installed.
Make sure that the battery power is at least 7 V.
If it is below 7 V, the power is not turned on or low battery picture is
output.
When the
screen is
dimmed
Please replace the battery. Depending on the voltage consumption of
the battery, the screen may become blurred.
the battery

picture is
displayed
This indicates when the battery should be replaced. Please replace
the battery.
When the
measured
value is [0.0]
Check that the light source is on.
For UV index meters, measurements may be impossible on cloudy
days.
Make sure that the incident surface of the sensor probe is
perpendicular to the light source.
Check the detection wavelength range of the measuring instrument
and the wavelength of the light source.
The detection wavelength range can be found on page 4 of the
manual and on the back of the measuring instrument.
When the
measured
value differs
depending on
the
light source
Please check page 15 relative response curve.
Even if included in the measurement range, the output value may vary
depending on the wavelength of the light source.
The calibration light source information for the measuring instrument
can be found on page 14.
When the
measured
value is
measured
low
In the case of a UV index meter, the measured value may be low or
not measured on cloudy days.
Make sure that the sensor measuring surface is positioned
perpendicular to the light source.
If the angle is tilted, accurate measurements will not be made.
Check if there is foreign substance on the sensor measurement
surface.
Foreign matter such as oil or dust can cause a decrease in light
quantity.
When power is
off
during use
If sleep time is not “Infinite”, the power is automatically turned off.
In this case, it is in normal operation.
