9.1 Connection Diagram

The use of an external 1A fuse is recommended. Connect the supply terminals to your aircrafts power supply. The TC-1 
can be used on both 12V and 24V without the use of any pre-regulators. Ensure that the supply voltage will not drop 
below 8V during operation as this may result in incorrect readings.
