Chris, you are a LIAR. You told us you understand electricity. You do NOT understand it at all. When I was seven years old I know that you can not measure current like you show in the photograph. To measure amps, all current must flow THROUGH the amp meter, NOT along side of it. I have marked your photograph to show you how to connect the meter. For amp measurement, all of the electricity flow must go THROUGH the meter. The meter must be a part of the circuit. Do you understand? MAKE SURE you have the probes in the proper holes in the meter. MAKE SURE you have the meter set for DC AMPS x100. I fear you have already ruined the meter. GET A BOOK ABOUT UNDERSTANDING BASIC ELECTRICITY!! You have NO business trying to do HHO yet. You must understand the basics first. I will make a post to you with the photo.
