S = 7uV/mm, A (D or W) = 15mm | V = 105uV |

S = 7uV/mm, V = 20uV | D (A or W) = 2.85mm |

S = 2uV/mm, A (D or W) = 10uV | V = 20uV |

S = 3uV/mm, A (D or W) = 25mm | V = 75uV |

V = 9mm, PS = 30mm/sec (F = 55Hz) | D = 300msec |

V = 9mm, PS = 30mm/sec (D = 600msecs) | F = 3.33Hz (or mm/sec) |

PS = 15mm/sec, A (D or W) = 3mm | F = 5 uV |

PS = 60mm/sec, A (D or W) = 9mm | F = 6.7 (7) uV |

PS = 30mm/sec, A (D or W) = 15mm | D = 2000msecs |

PS = 60mm/sec, A (D or W) = 15mm | D = 250msec |

A (D or W) = 1mm, V = 15uV | S = 15uV/mm |

S = 15uV/mm, V = 50uV | D (A or W)= 3.33mm |

S = 300uV/mm, V = 50uV | D (A or W) = 1.66mm |

D (A or W) = 50mm, V = 100uV | S = 2uV/mm |
