Introduction - Horizon Fitness P-1000 Installation Instructions Manual

INTRODUCTION

Thank You for purchasing the Horizon Instruments' P-1000 Digital Aircraft Tachometer. Many features have been incorporated into the
design of the P-1000 insuring simple operation and long life. The P-1000 represents the state-of-the-art in applying computer
technology to aircraft engine control and will prove to be invaluable in the reliable and safe operation of your aircraft.
The P-1000 functions as two fully independent digital tachometers that monitor the signals received from the primary circuits of the
aircraft's magnetos. The internal right and left tachometers independently determine engine RPM, which is then average and displayed
for the pilot. The superior reliability of the tachometer design is due to the use of two separate magneto signals to generate two identical
RPM readings. If either magneto fails, the tachometer will continue to display RPM from the remaining functional magneto. No external
probes or sensors are required to be installed in the harsh engine environment, further reducing the possibility of failure, and simplifying
installation.
Easy installation is facilitated by wiring the P-1000 to the P-Leads of the ignition switch. In most cases, no additional wires need be run
into the engine compartment.
To be sure of obtaining the best possible performance from the P-1000 please be sure to read this Instruction Manual carefully and
become thoroughly familiar with the operation of the P-1000 before staring its use.
KEEP THIS MANUAL HANDY FOR FUTURE REFERENCE.
