There is some difference
in reading between range
L and range H when
switching.
Is the light selection ring
smoothly rotating?
Does the light receptor go up
and down smoothly?
When the location of light
selection ring is not correct, the
measurement may be wrong.
Check if it is located properly.
The torelance range of
measurement for product
assurance between range L and
H is ±
８
MK-1.
The sensitivity of touch
screen is not good.
Is there any difference between
the touch panel sensor position
and actual touched position?
According to this operating
manual “8-1. Adjust Touch
Panel” (
P177), proceed
the adjustment of touch panel
position.
To prevent misoperation, the
resistance lm type touch panel
is used instead of electrostatic
capacitance system touch
panel used in the general smart
phone. Press the touch panel
with your nail if the sensitivity is
not enough.
In some cases, the
measuring time is longer.
Are you measuring the ambient
light with range H by mistake?
For ambient light measurement,
please use the range L. If you
use the range H, the less light
through ND lter is coming into
the sensor and it takes longer
time to measure.
This product uses the spectral
distribution type sensor, so
depending on the illuminance
of light, the measuring time to
display the reading will vary from
1sec. to 15sec.
