The Solomat 4000 of Doom

[Zombie]

I lucked out and won a Solomat 4000 at an auction. and I would like help figuring out what is wrong with it. You power it on, and it starts logging, and you can't stop it.

Don't suppose you have or found a manual for it? Is there some sort of procedure to start logging when you turn it on or is that normal behavior? From the ignorant searches I looked at it looks like it has a control panel/membrane input. If those are damaged or stuck I would think if it's just one button like start you might see similar symptoms. Is it logging real data or gibberish?

I can't really tell, I have a manual on it.

Hi.. I just stumbled upon this forum while looking for a Solomat MPM 4000 user manual. I also have one of the 4000/4013 modules, but find the menu access fairly complicated.

If you search for MPM4100 (different model, probably one series newer 1990s), you'll find a PDF manual which will provide at least some info. You may be able to find a manual for the 4013 module in the future.

The 3V lithium battery (about the size of an AA cell, sits alongside the 9V battery) in the 4000 unit is likely to need replacing. I've added a 2xAA cell holder for a temporary 3V supply, and with a fresh 9V battery also connected, you may see better results.

I forget what my tester displayed when I first got it, but the LCD should display:
4000
*MPM*

Then a (year) 19xx
(date) 3 JAN

Then a time? maybe, with more digits n:nn nn:nn

Then a reading and parameter symbol over a socket number
0000 (flashing if no probe is attached) and Px (parameter such degree F possibly another measurement type)
SKT 1

If you don't see the above sequence of displays, then it's likely that the 4000 isn't going thru it's normal startup procedure/firmware POST or whatever it needs to begin operation.

If you have probes for the 9-pin sockets, plug one into socket 1, 2 or 3.. and press the Next Socket button until the socket with the probe comes up on the display.
If the probe isn't functional (such as open lead in the cable) you should see 0000 flashing, or a somewhat sensible reading if the probe is good.
Definite maybe.

The bottom of the 4013 module should have a label showing some of the functions that are accessible.

If you don't have 9-pin probes, you might have a K-type thermocouple you could try in the#4 socket, or a hi impedance pH (or other probe) you could try connecting to the #5 BNC socket.

Some of the probes are very delicate, so if they appear to be in good condition, it might be worthwhile to store them in protective cases.

good luck,
