    a stab in the dark...

    Before I open this box up, I thought I'd ask here to see if anybody out there has the schematics and/or parts diagram of an X-Rite 310TR densitometer.l Or, barring that, if anybody has actually opened one of these up and replaced the battery responsible for keeping it's clock ticking and it's calibration data while it's powered down.

    It's an old beast (this one was in use in 2000 according to some notes in the copy of the manual I received when I obtained the unit) and I'm not willing to spend too much on it.

    Thanks, Dave

    The year 2000 is old? Wow. Now I feel old, and I'm probably younger than at least 2/3rds of the people here...
    An awful lot of electrons were terribly inconvenienced in the making of this post.

    f/64 and be there.

    14 YEARS AGO IS NOT OLD.

    gad.

    No, I've never opened one of those up. If it uses a battery, though, one would think it is easily replaceable. I'd start with the bottom plate and see if it's obvious.

    olde

    I just purchased an Agfa DF-6 Cadet box camera. It was made around 70 years ago. Now THAT is old. It still works but I need to find some Agfa Plenachrome film for it....

    I have a simple measure for old versus new. Any equipment younger than I am is new...made since 1951. I don't have too many new cameras, but I do have new(er) darkroom gear.

    I would agree with a previous poster that it SHOULD be straightforward... but that doesn't mean it will be.

    If you can't find an answer here try asking over at the Large Format Forum, between these two forums I'll bet someone has your answer.

    Er, Dave said it was IN USE in 2000, not that it was made then. I think he just wanted us to know it has only been rusting for a dozen or so years, not 50+.

    Way outside my sphere of competence, Dave. Good luck!

    14 years is not that old but if this is a rechargeable battery (which I suspect after reading the manual) this probably would be defect after 14 years.
    In this case you would have to desolder it to change.
    Or it might be a RTC module with internal Lithium cell rated for 10 years. In this case probably bad luck.
    Regards,
    Andreas

    I agree with Andreas; 14 years may not be old for equipment, but for many batteries it borders on prehistoric. I had forgotten about RTC chips with built-in batteries, that could prove quite challenging (and annoying).

    If the OP is lucky, there might be some sort of "coin" cell on the PC board. I have an enlarger timer that screams when I first turn it on (no matter how the switches are set) until I bump the time off zero. I'm now wondering if it used to remember the settings and lost its battery but I've been too lazy to look (and have no manual).

    My understanding (from reading old posts) is that there is a soldered on battery on one of the circuit boards inside the beast. Simply removing the bottom panel doesn't give access.

    That's why I was asking if anybody had actually opened one on the past or had diagrams of done sort.

    I will post over at LFF too and see what happens.

    And 14 is not old. Likely rates as one of my newest pieces of darkroom equipment.
