Temperature, Voltage and Optional RPM Sensors
The TM1100 includes a temperature and external voltage sensors. Optional RPM
sensors are available for Gas/Glow and electric brushless models to monitor RPM.
Temperature Sensor
To monitor the temperature of most any component, secure the sensor on the object.
It must come into contact with the surface to get an accurate temperature reading. You
can loop the temperature sensor around the engine’s cylinder head to assist in tuning
an engine. To monitor battery temperature, you can wrap the sensor around the battery.
The mounting position of the sensor, especially on gas or glow engines, will result in
different temperature readings. So it’s important to experiment with different positions.
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.
