A replacement EPROM with the latest firmware for the 6048 meters arrived from Prema on Saturday morning. You can download the zip file with the images of the EPROM and details on how to add the calibration data for your own 6048 to the image before you burn to your EPROM from: <http://www.eevblog.com/forum/metrology/possible-problem-with-prema-6047-or- 6048-meters/msg1408331/#msg1408331> Make sure you take a backup of the original image before you start (just in case). I've also uploaded the zip file to ko4bb.com and Bruce Lane's repository at ftp.bluefeathertech.com but it may take a while to show up. Dave
