WebUsing your flame source such as a lighter, and place the tip of the thermocouple into a flame. As it heats up, attach one lead of the meter to one side of the thermocouple. Then attach the other lead to the end of the thermocouple by the igniter. A working thermocouple will produce a reading of 25 to 30 millimeters. WebThermocouples have positive and negative wires so when connecting them you need to make sure that the polarity of the connections is correct. This also holds true when adding extension wires to the circuit. Remember the red wire is negative when using ANSI/STM color-coded thermocouples (white for IEC color-coded thermocouples). small black shaggy dog
