Question about Metz mecablitz 45 CL-4 TTL Flash
Does anyone have a circuit diagram for the Metz 45 CT-1 please?
One of my units gives an output approximately 1.5 stops too low, is there an easy setup to correct this?
I have an accurate flashmeter, and a total of 7 Metz 45 series flashes.
I'm tempted to swap the photocell with another unit, but since the unit is firing consistantly low it would suggest that the photo cell is too sensitive!
I have a 45CT-1 Service Manual, but it's in German. If I knew what to look for, I could probably find what you want. I know some German, but not enough to follow the technical description in the manual.

During the flash impulse the "photocell", actually a phototransistor, charges a capacitor with current, proportional to the reflected light intensity. As soon as the voltage on that capacitor reaches the trigger voltage of a four-layer diode (which, in fact, is playing a role of a PUT) that turns on and triggers the quench thyristor. There is a trimmer potentiometer in the four-layer diode circuitry, which sets the trigger voltage. You can try to fiddling with that. But the culprit of the misalignment easily can be in any of the parts in the above described circuitry.

I think that they all slightly under expose, and would'nt muck about with the internals. Have you removed the flash diffuser that is clipped on the front?
