Thanks Joe and Jeff for the instructions. From the Celwave sheet I guess the model number of my circulator may be CC460-AA, the model number is stamped so close to the sticker border that the second A would be off the border...
In the meantime I also found a helpful document, also uploaded it to the files section, it's called 'EMR-Single-Isolator-Tuning-Instructions.pdf'. The instructions are basically all very similar... 73 Martin
