according to IEC 60268 and DIN 45406.
PPM Type I, IIa and Nordic.
Both meters with adjustable reference and
with analog & numerical peak-hold readout.
Polarity Test (with MR1 test signal)
Positive / Negative detection through internal
microphone or XLR/RCA connector. Checks
polarity of tweeters, midrange-speakers,
woofers, sub-woofers and cables down to 10
dB S/N input signal.
