I sent it to Quality Light Metric in, IIRC, North Hollywood. George told me that the galvanometer needed a new spring and that there were other mechanical problems. The cell was fine. I've never ever got a used light meter that was accurate across its range. Each of the three I sent for service (the Master V, a Lunasix II and a Lunasix III) came back working properly. |
