The schematic is online. It took all of three seconds to find it:

No, the DSE ESR meter is dugital, and works a lot better on the low
ESR caps in switch mode power supplies. It reads from .01 ohms to 100
ohms on the digital display, and has an automatic zeroing, if the test
leads are clipped together when its turned on. I have, and use the
DSE. I've tried the Creative, but it was almost useless to troubleshoot
the CPU power supplies on computer motherboards

The Creative is analog, with all the low ESR readings cramped
together at the end of the scale.
