Installation
Insert the temperature sensor connector into the port labeled TEMP/VOLT. The temperature
sensor is now active and the actual temperature displays on screen.
Installation
Install the backplate sensor in the backplate. Install the connector into the RPM port in the
TM1000.
Testing
Turn the transmitter and receiver on and scroll to the RPM telemetry screen. Rotate the engine
rapidly and the RPM should register on the screen. The RED LED on the TM1000 indicates the
sensor is picking up properly. You may need to adjust the sensor's position to optimize the pickup.
Move the sensor closer or farther away until you have a reliable RPM pickup.
External voltage
External voltage telemetry is commonly used to monitor flight pack voltage or you can monitor
ignition batteries on gas engine equipped aircraft. You can set warnings to prevent over-
discharging batteries.
Installation
Plug the connector of the voltage sensor into the TEMP/VOLT port in the Telemetry
module.
Attach the opposite ends of the voltage sensor (stripped wires) to the
voltage source you wish to monitor.
Note the polarity (Red = + positive /Black = - Negative).
Typically, you can solder the wires to the battery connector. At this point the
External voltage displays on the telemetry screen.
Note: A Y-harness is provided if you want to use temperature and voltage sensors
simultaneously.
Engine RpM Sensor
The optional engine RPM sensor mounts inside the backplate of aircraft engines. The sensor
picks up the crankpin as the engine rotates giving accurate RPM. Additionally, you can use this
sensor as an RPM pickup on any rotating gear/ collar or shaft that has a steel setscrew or other
backplate. The sensor picks up the crankpin only; on some engines if the sensor is too
