The LEDs react according to rear panel’s overs counter setting, which means that when PPM
integration time is greater then 0ms and overs counter is set to low values the LEDs may
blink often while the PPM level is still below 0dBFS. The opposite situation may also occur
when PPM integration is set to 0ms and it reads over 0dBFS; in this case the LEDs do not
blink at all because they are waiting for the minimum number of overloaded samples.
After an overload indication occurs (a red blink), the held LEDs become a darker red to
indicate that an overload detection occurred.
To reset the LEDs simply click one of meters.
