Gossen Luna-Pro S question

<p>On the Luna-Pro S dial, there is a ring you can set for correcting exposure. For example, you are using a filter that has a "x4" correction on it so you can set this ring to "4" on the LV correction scale and ..."it will automatically correct for the filter"... well, It only works if you first take a reading, set the dial as normal, then adjust that ring to 4 but subsequent readings aren't automatically corrected as the instructions indicate...<br>

lets say you get a reading of 18 on the scale, you set it to 18, it says (ASA 100) 1/125 @ f/8 so yes if you turn the correcting ring to 4 (2EV) it's going to say 1/125 @ f/4. BUT if you leave the correction ring at 4 (like the manual instructs), take another reading and get say 18 again, and set the dial to 18, it says 1/125 @ f/8, not f/4 like it should as per the instruction manual (says "It Will Automatically take into consideration..."...)<br>

Am I doing something wrong? or are you supposed to set it every time and I'm mis-reading the manual?<br>

<p>I have this meter and I don't see how you are getting this behavior. There is no need to take the reading first before adjusting the correction ring. If I'm using the same filter all day I'll preset the correction dial and it will give me the correct readings. Is it possible that some of the internal rings rings are sticking together so that when you move one another moves as well leading to erroneous results ? I've seen that happen before in some of my older meters. </p>

<p>I'll post pictures... also, it looks to be nearly brand new and doesn't appear to have been tampered with.</p>

<p>As you can see. I took a standard reading of my work area, a reading of 14, at ASA-100 gives a reading of 1/125 at f/2. If I move the ring to '4' (or -2ev) and take a reading again at 14, it is still at 1/125 at f/2. Is the yellow 'Transfer Scale' band supposed to move while turning the adjustment ring? or is it supposed to be stationary and only the white ring with shutter speed and EV rotate? Mine moves along with the shutter speed scale, I'm thinking that's my problem?</p>

<p>The yellow transfer scale is supposed to stay where it is, but when you set the VF x/EF the shutter speed should change by two stops compared to when it is usually set at 1 for no EF.</p>

Thank you, I suspected as much.

Problem is my yellow scale ring

is just painted onto the EV/TIME

disc so it has no choice but to

move. I wonder what's up with

that? Manufactured wrong? Poor

design? Oh well, it works if I

set it after taking a reading and

it's in mint condition so it's a

keeper
