Re: Hyperion Laser Power Meter For Sale: 2W & 6W Version
Problem with battery was diagnosed and solved. The meter no longer measuring (as if the calibration has been zeroed) is an entirely new problem.
I would suggest taking a current reading at the Battery terminal
and ask astralist if that reading is within his specs. I would suspect
that the current draw would be quite low when running on a standard
9 Volt battery.
On a side note...as astralist stated.. his circuit uses a 5Volt linear
regulator and for it to function properly it will require at least 7.5V
on it's input. Under 7.5 volts it will drop out of regulation.
If your 9 volt battery reads less than that then it must be replaced.
If your car battery's voltage is too low and it will not keep a full
charge and won't start your car..... you would need to replace your
battery.
