Can TC1 or TC2 be used to monitor the temperature of the sources?

TC1 and TC2 can be used to measure the temperature of any connected K-Type thermocouple. The temperature of the Tempe sensor is regulated through TC1, so TC1 would be unavailable for general temperature monitoring while the sensor’s temperature regulation system is in use. Even when TC1 is being used by Tempe, TC2 can still be used to read any K-type sensor head.
