Gossen light meters with 9V batteries

OK, I can't explain that outcome. Too bad.
Either way, I suspect self-discharge of your batteries is the main culprit. Try your light meter(s) with a regular alkaline battery and see how it goes. If the problem goes away, you know what the cause was.

I'll try again that waybut yoy refer to a'meter' twice. Once, you must mean the light meter and the other time the amp meter. Please be very clear.

Sorry again.
OK
1. Snap 1 connector to the connector on the exposure meter.
2. Snap another connector to the 9 V battery
3. Connect the red wire from the battery to the black wire from the exposure meter.
4. Connect the mulitimeter red lead to the red wire from the exposure meter.
5. Connect the multimeter black lead to the black wire from the battery
6 Set the meter on DCA 200m. Make sure the red lead is plugged into the right most jack on the multimeter.

Your meter has the resolution of 0.1mA. Which is barely enough to detect a drain because the 9V battery only holds 600mAh.

Gossen light meters with 9V batteries

I own several Gossen light meters powered by common 9V block batteries. According to their manuals, they turn themselves off after 2 minutes of no use. I don't use them constantly, so, they rest in a drawer between shoots (supposedly turned off). But, too often, the battery is dead when I need...

Seems like eveything except the obvious has been tried...

I used to use alkaline batteries for all meters including non photographic meters because they consume too little power and rechargeable is likely dead whenever I need to use the meter. For example the mulitmeter, at home I may not use it for a year or so but when I need it I would have no time to charge it. But in recently years I have had so many leaked alkalines batteries so I have to look for alternative.
I am not too worry about the environment like Ralph.

It has been about a month since the last charge, and the batteries are still working. I can live with that.
