You're right, my bad. It is a DMM. I just wanted to know what was the difference between the ac current setting on the meter and the dc current on the meter. I have owned the meter over 6 years and I have always put it on ac amps. I was checking current draw from a power supply and checked the ac side, then the output side, then wondered why I had to change the meter since current is current, right? I understand how ac current is alternating and dc is steady. Thank you for the reply.
