PARAGRAPH PARAGRAPH CONDITIONS DESCRIPTION OF CONDUCTED TESTS CONDITIONS DESCRIPTION OF CONDUCTED TESTS NUMBER NUMBER Equipment Identified as “X”. Tested to categories A1 & B1. -
Page 8: Certification
The Supplemental STC information supplied with a P-1000 is dependent upon the information supplied to Horizon Instruments, Inc. at the time the P-1000 is ordered. If this information is erroneous, applicable to a different type of aircraft, or missing, do not proceed with installation. -
Page 9: Theory Of Operation
THEORY OF OPERATION The P-1000 operates by timing the alternating electrical signals generated by an operating magneto, see Figure 2, and mage available on the magneto’s “P” or grounding leads. Because reciprocating engine aircraft have two magnetos on each engine... -
Page 10: Display Features
STATUS INDICATORS When no signal is received from either the right magneto or left magneto (See Figure 1), the P-1000 will turn on a corresponding right or left red magneto signal “Status” indictor. The status indicators are located on the upper left of the tachometer face and can indicate a hot magneto (open circuit) or grounded magneto (breached insulation or broken ignition switch) condition. -
Page 11: Rpm Acr Indicators
RPM ARC INDICATORS Three large LED type indicators are provided at the upper right corner of the P-1000 face to indicate the RPM operating range of the engine (See Figure 1). A “Normal Operating “ green, “Caution” yellow, and “RED-LINE” red LED are provided. The RPM settings at which these indicators activate are presettable at the factory. -
Page 12: Tachometer Control
RESET The computer within the P-1000 may be manually reset if it is suspected that it is not operating properly. To accomplish the reset, simultaneously press the center and right buttons. The P-1000 should proceed through its self-check tests and resume full operation. -
Page 13: Installation
Horizon instruments, Inc., please call for a return materials authorization number so that your product can be properly and expediently tracked and processed. Verify the RPM arc information placarded on the face of the P-1000 to correspond with the red, yellow and green arcs on the existing mechanical tachometer, or to the engine/propeller manufacturer’s specifications. -
Page 14: The Installation/Check-Out Sequence
10 Attach the white wire to the circuit breaker load terminal. 11 Attach the circular connector to the P-1000. Be sure to screw the retaining ring all the way to the base of the mating P-1000 connector. Turn on the main power switch and verify that the P-1000 turns on. The P-1000 will flash the tachometer’s configuration number, which identifies the tachometer for use with a specific aircraft/engine combination, and a software version code. - Page 15 24 Press the “Trap” button and hold it again. Observe the maximum engine RPM achieved since the “Clear” button was pressed. 25 If possible, during engine operation compare the P-1000 RPM readings to your mechanical tachometer to verify that the P-1000 is operating properly.

Page 16: Connections
P-leads at the ignition switch (see Figure 6). Do not connect any part of the P-1000 to a spark plug wire or any part of the high voltage secondary ignition circuit as serious damage may result to the P-1000 and to the pilot. Do not cut into any existing shielded P-Lead wire. -
Page 17: Removal Of Mechanical Tachometer
INSTRUMENT MOUNTING As shown in Figure 7, the P-1000 should be positions to allow for optimum view of the LCD display. The pilot’s line of sight to the P- 1000 should be within the indicated angles. Viewing from greater angles will result in decreased readability of the display in low-light conditions. -
Page 18: Circuit Breaker
One terminal of the circuit breaker should be connected to the primary power buss (not the avionics buss), and the other terminal will have the white battery wire from the P-1000 attached to it. The cable supplied has not yet had its power wires terminated. -
Page 19: Maintenance
The P-1000 should be kept clean of dirt, oil, and grease, by using a mild soap and water mixture with a soft non-abrasive cloth to maintain its appearance. Do not use harsh soaps or cleaning solvents as they can damage the case and its appearance. The P-1000 is not a sealed instrument;... - Page 20 (Greater than allowed for this aircraft). systems.
