Setting Thermocouples Function
Select Thermocouples from the Work mode menu to set them up.
The thermocouples (TC) can work in three different ways depending on what is needed.
C
· Control: the unit maintains the selected temperature.
P
· Protection: the Heater Unit stops if the TC reaches the selected temperature.
· Info: the TC temperature is shown on the work display.
The TC1 is always working in Control mode for the Temperature mode as well as for Profiles mode.
The temperature of each TC can also be selected from the work display.

Recommended Guidelines

1. Place the control thermocouple as near as possible to the component being worked on.
2. If there are any sensitive components, use a thermocouple as protection.
You can select the protection temperature in the thermocouples menu. If the selected temperature
is reached, the Heater Unit will stop the process and a warning message will be shown.

3. We don't recommend exceeding ramp-up rates over 3 - 4 °C / sec (5 - 7 °F / sec) so as to
reduce the risk of thermal stress on the PCB.
