Status
Check item Measure
The measured values are
wrong
Is the measuring mode wrong?
(Such as measuring in Ambient
Light Mode in ash light)
Check if the measuring mode is
correct. (
P22)
Are you using the pre-ash
function when measuring in
Cordless Flash Mode?
In Cordless Flash Mode, the
measurement value of the main
ash may not be displayed
because the pre-ash is
measured at rst.
Cancel the pre-ash function.
Setting values and
measurement values of
the spectrometer are not
in the camera settings
Do the shutter speed and iris
setting step of the camera and
the shutter speed and iris setting
step of the spectrometer match?
Some cameras can select 1/3
step, 1 step and 1/2 step, like a
spectrometer. Match the step of
the spectrometer with the step
of the camera. (Shutter Speed
Step) (
P128)
The memory function
cannot be used
Is the comparison mode
activated?
The memory function cannot
be used when the comparison
mode is used. Deactivate the
comparison mode.
Is "Memory Full" displayed when
pressing the Memory Button?
The memory can store up to 99
values.
Clear unnecessary memory
values in advance, measure,
and memorize it.
The spectrum graph
does not appear in the
measuring of blue LED.
Is the measured light source
bright enough?
If the measured light source is
not bright enough, increase the
output of the light source and
measure it.
There is a possibility that
LED with narrow spectral half
bandwidth cannot give enough
light amount to measure
properly.
There is a rattling in the
light receptor.
Is the light selection ring
smoothly rotating?
Does the light receptor go up
and down smoothly?
Small rattling is not malfunction
and necessary as the
mechanism for switching.
However, when the rattling is too
much, or there is any abnormality
in rotating the light selection ring,
there is a possibility of faulty in
the products. Contact with local
retailer or Sekonic.
