Bump
Sorry to wake up such an old thread, but I finally got not one, but two good Volt Ohm Meters. One is a Micronta 22-205 by Radio Shack, that nobody can seem to find any information for; and a Sompson 260 series 6M. I found what I needed for the Micronta, which is the 22.5 volt battery to be exact. However there seems to be an issue with the Simpaon meter I purchased. I've already gone to the Simpson260 web site too. Everything on this meter is fantastic. In fact, it appears to be in "like new" condition inside and out. All of the components look great, but the 10K Ohm scale will not zero. I thought it might be a calibration issue, or a blown or bad resistor, but I really don't know. All of the contacts are clean, the meter movement is perfectly smooth and as I stated, it is in fantastic condition.
The schematic I found for this particular model from the Sompson 260.com appears to be the wrong one as well.
What I would like to know is very simple... Inside there are several variable resistors. Each has it's own function. There are other static resistors as well. Does anyone know EXACTLY what I need to do to get the 10K Ohm scale to properly xero out and still be at least somewhat accurate until I can have it calibrated?
Thanks for reading. And again, sorry for waking this old thread.
