content: I just picked up one of these inexpensively and it seems to work very well. Anyone have any experience with these? Based on chip dates I calculate a build of about 1995. It seems to work on all functions, but 'processes' a little slow. Also - looking for a complete manual. The service info is out there, but is only a section of the whole manual.

content: I have one. Remove the internal nicad battery, if fitted. Mine was also cheap, but has a lot of corrosion from the battery attached to the lid leaking down the wires to the PCB. It has been a work in progress repair project for the last few years. Just a matter of installing the new parts...The service manual is online in a number of Pdf files. I think is the full thing. If you can't find it, ill have a look here.

content: I finally dusted this one off. Replaced the nicad battery pack and it's working well with one exception. Anything higher than about 1meg on reads off. I connect a 1% 3.33 meg resistor and it starts out at about 2 meg and very slowly climbs to about 2.8 meg. DC volts, AC, etc are all fine.Low ohms and 4-wire seem to be okay.Maybe relay(s) contacts?Still looking for the complete manual. All I could find was the calibration section of the manual.

content: User & Service Manual (multipart --> 6 files) :http://www.eserviceinfo.com/download.php?fileid=62715I have attached a poorly scanned schematic (don't remember where I got it).Autorange is quite slow and I don't like much the sequential function selection with up & down buttons.Mine has a (quite good) LT1021BCH-5 10V voltage reference.Michel.

content: Dear mbear2k ;i am interesting about the digital multimeter DP100 too, and i looking for the complet manual users, i fount just the forty first pages and the essentially for me is the connection with the rs-232, to create a graphical interface with LABVIEW, I've searched in internet the adresse mail of ANALOGIC CORPORATION to sent a letter asking him to transfer the user manual, but apparently the analog company and changed its industry. So if there is news on the manual I hope to post here or send it to the following email address: ing.smohamed@gmail.com.thank you in advance.

content: I'm aware this is a very old thread, but i figured i'd spare anyone else from having to download a 6 part PDF.https://www.mediafire.com/file/aptnly0gx57yh48/dp100_ilovepdf_merged.pdf/fileIt should probably be added to archive.org too i suppose...

content: I apologize for reopening such ancient thread, but the information here was very helpful so far. I just got one from user Ground_Loop and it has been giving me some work to do. What initially was a power supply issue (already fixed), now it seems to have developed to a general issue on the analog part - a +10V net is around 8.5V, which is throwing off the autorange and the overall functionality of the equipment.I am using the schematics provided here, but wanted to know if someone else has a better resolution one. Although the existing one is immensely better than nothing, there are quite a few things that are hard to read and I feel it might be missing one detail or another.So, if someone has a better scanned schematics to share, that would be very helpful. Also, if someone has the error codes of this equipment, that would also help (I am getting errors 02 and 03 on occasion, which I think are related to calibration values but I can't be sure).

content: I attach below schematics with stitched pages - it becomes easier to follow. Just download the file and rename it to .rar extension (the forum does not allow .rar extensions. Go figure)Beware: the small .rar file blows up to a 300dpi 160MB Tiff file. I tried to preserve the most quality of the original schematics PDF linked above.(edit) added the .pdf file created from the TIFF. Perhaps it is easier to browse and print.(edit2) added the firmware of my meter, which is an early version 1.1
