Broncolor FCM probe

Has somebody ever worked with the Broncolor FCM lightmeter ,connected with the Broncolor FCM probe in a Sinar 4x5 meterback ?
I have problems in measuring shadows.

To clarify my question further :
The display shows

"UNDER"

when measuring medium shadow parts.
IMO these shadow is light enough to be measured without problems.But the FCM lightmeter/FCM probe combination can't measure it!:confused:
(Aperture is open ,ASA is set correctly,Lenscap is taken down etc)

FCM lightmeter used without probe works fine.I compared it with my Gossen Lightmeter and it shows not more than 1/10 difference in various situations.


I would be happy if someone could give me advice.

As I posted this question in two other forums,here the answer I got there:

The FCM probe is designed for use with flashlight.

With availible light the sensitivity is not enough and
it is than probably better to use a regular lightmeter,or maybe a spotmeter.

Yes - that's what I would have said - pump up the light... the probe has the disadvantage of having to work in incredibly dim post-aperture light...
