I have a PM2525 but, alas, it does not have any communications ports on the back panel, only a plastic cutout where something could populate the space.
But that's OK with me. Because I find the non-backlit display nearly impossible to read, the power switch inconveniently placed on the back panel, the 4-wire ohms function needlessly having to use the probe socket, the horrendous calibration procedure which needs to be done at two different temperatures, the rather bland specs, and especially the internal function selection switch which is run by a motor to be an example of how not to design a multimeter. Of all the dozens and dozens of 4-1/2 to 5-1/2 digit DMMs I've come across over the years, this one is my least favorite.
All my personal opinion. Some people may not agree. That's OK.
