    Instrument: Instrument: The M-1 is a precision manifold pressure instrument featuring a 210 degree analog display and a digital display. These two displays have many advantages over conventional analog gauges as described below. Also, the M-1 features long-term accuracy and reliability. Since the M-1 does not incorporate any moving parts (needles, bearings, springs, etc.) there is little to go wrong or wear out.
  • Page 8: Installation Instructions

    The M-1 can detect a change in manifold pressure for every 100 feet of elevation or .1 inches change in barometric pressure. This allows for precise setting and monitoring of the manifold pressure. If the digital display backlight has been permanently powered up (as recommended), the digital display will be easier to see during low ambient light conditions and at night.
