It is just a capacitor that holds the meter higher and has no active powered pep circuit.
My SX-400 will not work in the PEP mode without power applied (through the wall wart).
Hmmmm. SX-1000.....SX-400? But I have only had mine since 1993. Not such a LOOOONG time as CK.
Regardless, I like the SX-400. It is compact (doesn't take up much real estate), seems accurate and the meter is lit (better for the Senior eyesight).

Anyone have any experience with this meter or any of the Diamond meter's?
I'm in the market for a new meter and asking for opinions. Thanx!
