Hello everybody, this is may first message in the list, I hope it's the right place to discuss this topic. Recently I added to my small collection a solartron 7061 multimeter (all the collection is made by another 7060 solartron and a fluke 8520a). It seem to function properly, only it is off calibration. When I first powered on it show the message "initialized" on the main screen. After trying a bit the various voltage and resistance ranges I realized that it was off calibration, errors were in the half percent order and also changing range changed the error, but the measurements all were about right, so I hope there aren't big failures in the analogue board. After I turned the calibration key and entered the cal menu, soon the instrument showed the "cal not done" message, I returned the cal key on normal position but now the instrument shows "calo" message to the side of measurement. Also I tried starting it without the dq2816a eeprom and it had the same behaviour than it had with it mounted. The Nicd battery is also dead. I'm suspecting the EEPROM DQ2816 IC113, does the instrument store there the cal constants? I found the operating manual on internet but no luck finding service manual or schematics. Help is very appreciated, with the intrument and also in finding the service manual. I have put some photos here: http://www.eevblog.com/forum/product-reviews-photos-and-discussion/solartron-7061-help-and-come-photos/ Thank you.

Hi, Fabio! I'm think answer is on the page 8.3 of the 7061 Operating Manual. Besides, 7071 manual says, that "Refresh" command must be executed to ensure EEPROM proper operation. Mickle T.

I got one too, it would not hold calibration until I replaced the battery. I am also looking for a service manual. Found a site where the should sell them but no answer after to mails. Dave from Artek does not ave one too but if there was enough demand he could maybe rent one to copy. Mine becomes very hot. This should be nomal but I feel more save if I can check powersupply rails ect. One time It got so hot, it smelled like I would start to burn. Besides it shows non lineair behauviour and the 1V and 10V give different values. ( not big, just about 30-40 uV but i like to get it as good as possible) Hope someone comes up with a service manual.
