I agree with Atilla from what I have seen. Its actually somewhat difficult to measure this level of current. But all is not lost. Even if the unit is drawing 1-10ua because something is going wrong. Simply add a battery holder and 2 X AAA or AA or ... Whatever it takes to keep the unit going. If you mount the batteries externally you can easily replace them and check the discharge rate. Its a way around the problem if you simply can not get a replacement or its totally embedded on the board. Best of luck Paul WB8TSL
