Procedure Refer to the Operation section if you need details of the instrumentation and how to operate it. Switch on the front Mains switch (if the panel meters do not illuminate check the RCD at the rear of the service unit, the switch should be up). Set the heater voltage to 20 Volts. If using the HT15 software to control the accessory remotely then the voltage can be controlled using the control box on the mimic diagram screen. If operating the accessory manually using the T10X/HT10XC console then adjust the VOLTAGE CONTROL potentiometer to give a reading of 20 Volts on the top panel meter with the selector switch set to position V. Monitor temperature T1 regularly using the software screen or the lower selector switch. When T1 reaches 80oC reduce the heater voltage to 9 Volts (the initial higher setting will reduce the time taken for the temperatures on the rod to stabilize). Allow the HT15 to stabilise. Monitor the temperatures using the software screen or the lower selector switch/meter. If using the software, select the icon to record the voltage and current supplied to the heater, the temperature at each position along the rod (T1 to T8 and the ambient air temperature T9). If operating the equipment using the console then record these values manually from the console displays. Set the heater voltage to 16 Volts then allow the HT 15 to stabilize
