Autool DM303, Some of my favorite features demonstrated.

The DM303 is a multi-function tool with some unique features. It does basic volt, ohm, amp, and diode measurements. I didn't cover that. It does more special tests that i didn't cover. I purchased this tool because i thought the ability to decode can bus data was interesting and may be useful. The function generator with variable duty cycle is another capability that none of my other tools have. The price paid for the features is impressive to me. I purchased from the Autool store on eBay.
