PME 3 prism not working correctly

Hi all,
I have a PME 3 metered prism. It acts strange and maybe somebody could help me out. I installed a new battery (EnergizerA544 Alkaline, 6V) I adjusted the ASA and the max Aperture value. When I press the "meter" button to get a reading, the LEDs light up for a fraction of a second and then they are dark. Sometimes - when I get lucky - the meter seems to display the correct meter number in the LED display for a fraction of a second. It acts like there is a loose connection somewhere.
Before I get out my screwdriver I would ask maybe somebody encountered this problem before and has some words of wisdom :)

Is it worth to take appart? (I'm a laptop technician, so small screws don't scare me)

Any help would be appreciated.
 
Battery?

I try to keep things simple.
Most of the time that helps.

My guess is your new battery is not as good as you think it is.
The symptoms indicate a battery that has just enough power to switch on the leds ands dies after that.
Could also be dirty contacts in the battery box.

If you are about to dismantle the PME because this is not the cause drop me a PM with your email address.
I have an exploded view of the PME viewers.
You will be amazed what is in there!
