content: Hi there. I'm selling a nice piece of equipment. IM6 Megohmmeter comes from a Danish company called RE Instruments. It can measure high impedance from 1Meg to 1 Petaohm (1000000 Gigaohms) with a selectable voltage source from 1 to 1000VDC. Also, it measures current from 1mA to 1pA. There are some photos with a couple resistors and a capacitor. The resistive box contains a 100GOhm resistor divider and the fourth picture shows the leakage current of a film capacitor.It is a great choice for finding leakage within relays or capacitors where you can set the voltage between the test leads.I did a couple measurements showing its pretty good working condition. The only thing I've done in the past was to change one or two electrolytic capacitors in the power supply section. Everything else around the PCBs is intact! I believe the push button caps are not original, but it doesn't matter the measurements.There are the manual and the schematics+ calibration manual if someone wants to have them:http://bee.mif.pg.gda.pl/ciasteczkowypotwor/RE%20Radiometer%20Copenhagen/IM6%20Megohmmeter%20(Manual).pdfhttp://bee.mif.pg.gda.pl/ciasteczkowypotwor/RE%20Radiometer%20Copenhagen/IM6%20Megohmmeter%20(RE%20Technology%20Manual).pdfI'm asking 300 Euro for it. You have to add shipping. It is heavy, so I predict something in the range of 50-60 Euro for the shipping from Bulgaria to the EU.

content: I see zero evidence of malicious activity from these two links.It's a plain Apache file server with directory listing enabled, directly returning two PDF files that don't give a single alarm on virustotal.The input preamp is a complicated JFET based design, I still can't understand it after looking at it for 15 mins.

content: Hello: very fine and rare!Radiometer Denmark (now RE) units, are similar in capability to Gen Rad 1863/1864 megohmmeters.https://www.ietlabs.com/pdf/Datasheets/1863-1864.pdfBon Chance,JonPS: site is HTTPS but PDF link is HTTP, thus browsers warn of security issues in PDF.
