Hameg HM8012 Multimeter – -Fuse Change

While testing a PSU I blew up the 500mA current range of my Hameg HM8012 Multimeter. Because it was a double PSU I blew two at the same time. No problem I thought. Just replace the fuses and I am done. First I looked in the manual to find out what fuses to use. To no avail. On the contrary it says: “In case of an open fuse the instrument has to be sent in for repair. A change of the fuses by the customer is not permitted”. What??! Those instruments are mostly used by tech people which know how to replace a fuse. And a fuse is for protecting the device from damage. If the device needs service after the fuse blows the fuse is near to useless. A simple replace of the fuse should do. I located the service manual and looked up what fuses to use (1A/600V 10.3x38mm).

Just open the lid:

Close the lid. Test the device. In my case the fuse worked as intended. No damage done to the Hameg HM8012 Multimeter. And no need to send it in for service ($$$).
