Main Output The Main Output current is regulated via the feedback from the temperature sensor in the main heater The Auxiliary Output is not regulated and follows the changes in current made to the Main Output For best results both heaters should have similar heater resistances within a few ohms The Auxiliary heater temperature can be momentarily shown on the LCD display by pressing and holding the SELECT keypad The temperature will be shown under the ACTUAL TEMP text on the Front Panel display The Auxiliary temperature can also be viewed from the command line interface by typing taux Note the Auxiliary temperature is only updated once every five seconds and only when the sensor is of the PTC100 type Note The Auxiliary input is only compatible with PT100 sensors 10 1 Operating the Gas Cell Heater Due to the unbalanced nature of the Auxiliary Output it is best to connect the heater with the least resistance to the Main Output and the higher resistance heater to the Auxiliary Output This will ensure that the Auxiliary heater does not exceed the TMAX level which is only monitored on the Main Output Determine the main heater by connecting both heaters to the unit setting the target temperature and enabling the TC200 Once the main heater starts to show an increase in temperature press the SELECT keypad to view the Auxiliary temperature If the Auxiliary temperature is greater than the Main temperature disable the heater turn
