Thank you Jerry, The idea of destroying an instrument to make the socket fit a plug is one I would not do! Worst case, on a cheap and nasty bit of kit, I might consider changing the socket for triaxial BNC, but I have no desire whatsoever to do that on the 4339B, which sell for several thousands of dollars. I have already sent the meter once to Keysight for calibration, which they can obviously do if it has the right connector on it. If one started changing the connectors, then it would never get calibrated again. Depending on the age/value/rarity of the connector, I might consider other options, but not this time. On Monday I should have a partially complete Agilent 16339A component test fixture https://www.ebay.co.uk/itm/Agilent-16339A-Component-Test-Fixture/112871963210 arrive. (It cost me $400, which is more than the $350 I paid for the meter). That fixture will have the correct plug on it. HOPEFULLY there will be a manufacturer and part number on the plug. Also, I will have the ability to take a decent photo, so hopefully someone experienced has more chance of being able to positively identify the connector. I might try asking Keysight again. They told me the interlock connector was a Hirose, and knowing that I managed to work out a plug that fits. I've bought a couple of 4349Bs, which are quad channel high-resistance meters that take the same CPU as my 4339B. I'm hoping to do a bit of transplant surgery and hopefully get my 4339B to the point it can be calibrated properly - Keysight were unable to adjust it before as the CPU board apparently has a fault which is stopping the EEPROM being updated. When sent back to Keysight, it will have a 'heat transplant' of a CPU, and a new EEPROM, so all calibration data will be missing, as that's stored in the EEPROM. I'm pleased to say Keysight are not going to charge any extra to calibrate the meter with a blank EEPROM. So hopefully I will get this meter right.
