I just spoke with Fluke about calibration options for the 732A and how to connect an external battery pack.
There are three calibration options: 1. Z540 $700 2. Accredited $1000 3. Primary Standards Lab $1485 These are described on their website: http://us.flukecal.com/support/calibration-services/electrical-rf The Fluke part number for the male plug to connect to the socket on the back of the battery module, 732A-7005, is 2181497 and is available for $12.75. I ordered two. With that, I can construct a transit case with room for external batteries and be able to ship it overnight to Fluke for calibration. The folks in calibration service suggested I send them an email requesting the value of the Thermistor and whether old/original calibration certificates might still be available and they would forward it to the folks that, at one time, were in charge of keeping that information. At one time, that information was kept but, according to them, no one wanted it. Therefore, they no longer keep that information. However, perhaps it might be available for this 'vintage' equipment. We'll see. Thanks to all for their help.
