[Leica] M6/M6TTL power consumption...

["Austin Franklin" <darkroom@ix.netcom.com>]

I measured the power consumption of the M6 (late) and M6TTL as follows:

Fluke 8020B MultiMeter
Setting for 1/15 w/ release depressed triggering meter 20ma for M6 and 200ma
for M6TTL
all others meter was set at 2ma

                               M6 (late)     M6TTL

OFF                               n/a         .000ma
1/15 no meter                     .000ma      .000ma
1/15 w/ meter                     ~14ma       ~26ma
after release no wind             .000ma      .000ma
after release wind                .000ma      .000ma
B                                 .000ma      .000ma
B w/ release depressed            .000ma      ~26ma (note 1)
shutter speed set to flash        .000ma      .000ma

So, it appears from this that the ONLY time there is ANY current draw, down
to .001ma, is when the shutter button is depressed and the meter is
activated whether it's an regular M6 or an M6TTL.  The OFF switch on the
M6TTL has no more of an effect than when the meter just isn't on.

The meter powers off after ~10 seconds.

Note 1: Though the M6TTL draws normal metering current when the shutter
release is depressed and the shutter speed is set to B, the LEDs in the
viewfinder are not illuminated.

Any inaccuracies you believe I may have made in my testing procedure or in
my results, please let me know, I am happy to run a particular test again.
Please don't "argue" with the results though, as I am only reporting the
facts as I tested them.

Regards,

Austin
