Hi to all from some weeks I'm using in my station 3 Mark L4 sensors with Larry's = ampli board. The output signal is very high, and a small events also near me saturats = the amplitude. The gain is at min. What I do to resolve this problem? In another station of our network, we use the Mauro Mariotti's ampli = board with the input resistor of 22k and all works fine. Can I do the same change? regards Fraancesco ItalyHi to allfrom some weeks I'm using in my station = 3 Mark L4=20 sensors with Larry's ampli board.The output signal is very high, and a = small events=20 also near me saturats the amplitude.The gain is at min.What I do to resolve this = problem?In another station of our network, we = use the Mauro=20 Mariotti's ampli board with the input resistor of 22k and all works=20 fine.Can I do the same change?regardsFraancesco =20 Italy
