I finally got one 10 years ago after a long search, because production ceased after a short time in the beginning '80ies -- the BERTRAM firm moved and is now producing other instruments and meters for industry clients. To investigate all details of the Spot Meter I succeeded in speaking with of the Bertram brothers and with the constructor, too. Important message for all users, because the 2x PX 27 cells are not available anymore: This meter has a circuit compensation! You can insert 4x CR1/3N or 8x SR44 cells.
In case of any question don't hesitate to drop me some lines, I still have an instruction manual.

Hi Steve,
I finally got one 10 years ago after a long search, because production ceased after a short time in the beginning '80ies -- the BERTRAM firm moved and is now producing other instruments and meters for industry clients. To investigate all details of the Spot Meter I succeeded in speaking with of the Bertram brothers and with the constructor, too. Important message for all users, because the 2x PX 27 cells are not available anymore: This meter has a circuit compensation! You can insert 4x CR1/3N or 8x SR44 cells.
In case of any question don't hesitate to drop me some lines, I still have an instruction manual.
Best regards
