２. Measurement
2.1 [Before Operation]
Checking and Replacing Batteries if need.
Replace the battery when
B
appears in the display area to indicate
battery exhaustion, or when nothing is displayed even if you push the
right side button.
In replacement, make sure the polarity(＋, －)connection is accurate．
Use two AAA type 1.5V alkaline dry cell battely.
2.2 [Measurement]
Turning the Power On,
and starting continuously measurement
Push right side button for an instant.
Display will appear and continuously Lux measurement will be starting.
you can read Lux value in continuously.
＊If measured value exceed 39999 lx, then ＯＲ indicator will blinking.
Turning the value hold
Push right side button again for an instant.
Display will fix measurement value.
Return to measurement
Push right side button again for an instant.
Display will return to continuously measurement.

-8-
Turning the timer value hold
The timer hold function makes measurements (holds the value)
after the specified time elapses.
If where you are or what you are wearing is going to affect the
measurement, you must move away from the meter. This function
enables you to set the time needed for you to move away from the
meter so that you can make accurate measurements.
In continuously Lux measurement, Push right side button again for a
while(about 3seconds). ＴＨ is light and Display will turn [111111]brinking.
That's means going Timer Hold.
After 10seconds, Measured value will be fixed and hold.
Turning the Power Off,
Push right side button again for a while(over 6seconds),
then power will be off.
(when it's in hold mode,power will be off more shortly.)
Automatic Power Off
The meter has an automatic power-off function to prevent unnecessary
battery usage when you forget to turn off the power.
If there is no key activity for about ５ minutes, the meter automatically
turns off.
Pressing side key while the meter is beeping extends the time until the
power turns off for another 5 minutes.
The automatic power-off function is disabled while the RS232C a plug
is inserted in the RS232C output connector function is being executed.

Characteristics of Relative Visible-Spectrum Response
The visible spectrum of light for human beings is from approximately
360nm to 830nm. Even within this narrow range, the sensitivity to light
varies greatly depending on the wavelength. This phenomenon is called
the standard spectral luminous efficiency and is indicatedby V(λ). The
characteristics of relative visible-spectrum response of lux meters play an
important role in illuminance measurement. It is important to approximate
the relative visible-spectrum response to V(λ). These characteristics are
stipulated in engineering standards(JIS C1609-2006)for certified lux meters.
The relative spectral response of an illuminance meter S(λ) is measured
at 5-nm intervals for 95 wavelengths to calculate thedeviation (f1’) from
V(λ). This method of evaluation is based on the performance evaluation
of the Commission Internationale de l’E clairage(International Commission
on Illumination; CIE).There are various light sources such as white light,
fluorescent lamps, and mercury lamps, and LED lamps on the market.
Normally, the relative spectral response of a lux meter is slightly off from
V(λ). So when a light source with a different spectral distribution than the
source that was used to calibrate the lux meter is measured, the readings
will be slightly off. The color correction factor is used to correct this error.
To make accurate measurements, we recommend that you correct the
readings by multiplying the color correction factor of the lightsource under
measurement. The following figure shows the characteristics of the relative
spectral response.

Chracteristic of Oblique Incident Light
When reading a book at night, the brightness differs between
reading under a light and reading a little farther from the light.
In such a case, you probably noticed that the book was easier to
read when you faced the book toward the light.
If the angle between the incident light and the line perpendicular
to the illuminated surface is defined to be θ, the illuminance of
the surface is proportional to cos θ.
This characteristic is standardized.
If the lux meter does not meet the standard, illuminance of
oblique incident light cannot be measured accurately.
The following figure shows the characteristic of oblique
incident light.
