Electronics International M-1 Manifold Pressure - Manual (Page 6)

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.
Installation Instructions
M-1
Important Information and Initial Check Out:
1. The installer and aircraft owner must read the Warranty before starting the installation. There is
information in the Warranty that may alter your decision to install this instrument. If you do not accept
the terms of the Warranty, do not install this instrument.
2. If you are not an FAA Certified Aircraft Mechanic familiar with the issues of installing aircraft mani-
fold pressure instruments, Do Not attempt to install this instrument. The installer should use current
aircraft standards and practices to install this instrument (refer to AC 43.13).
3. Check that any necessary FAA Approvals (STC's, etc.) are available for your aircraft before starting
the installation. The FAA Approved Model List (AML) is located at the back of this manual. Resolve
any issues you may have before starting the installation.
4. Before starting the installation, read the entire Installation Instructions and resolve any issues you may
have . This may eliminate any delays once the installation is started.
5. Check that the instrument make and model marked on the side of the instrument and on the invoice are
correct before starting the installation.
6. Check that the limit information on this instrument matches the published limits in your aircraft's P.O.H.
or Flight Manual. Also, this information may be listed in the T.C. Data Sheet for your aircraft. Any AD's
and/or STC's may set forth additional limitations on the operation of your engine. The limit information
listed in the AML is for unmodified aircraft and is intended for reference only. It is the aircraft owner's
and/or installer's responsibility to determine proper instrument calibration and range markings for your
aircraft.
On the front of this instrument you will find a red light marked with the maximum manifold pressure
information. If there are any additional red or yellow lights on this instrument, the operating range of
these lights can be found on a sticker located on the side of the instrument (see the AML at the back of
this manual to decode this information). This instrument designates any "Caution Range" with yellow
LEDs, any "Maximum and Minimum Limits" with Red LEDs and the "Safe Operating Range" with green
LEDs. The "Safe Operating Range" on this instrument is equivalent to the green "Normal Operating
Range" and any unmarked areas on a analog gauge.
