Talking Blue2 ESR meter
Talking version

This meter is exactly the same as the standard version, except that it says what's on the displays. This is for technicians who already know what are good and suspect ESR readings without looking at the chart of typical ESR figures.

The only functional difference is that the speaker volume is adjusted by holding the button down for a few seconds until the volume setting is displayed, and the volume changes by one step for each button press, including muting the sound.
