ATC2000 will control to the new 37°C, which is actually 34°C plus a 3°C offset.
1. Press the Config button on the ATC2000 to access the Configuration menu.
Press the Config button again until one of the following displays:
• Set RTD Offset–Adds temperature offset to the RTD probe reading
• Set TC Offset –Adds temperature offset to the thermocouple probe reading
• Set Plate Offset –Adds temperature offset to the heating plate reading
Fig. 18—(Left) Using the Up/Down buttons, change the RTD Offset.
Fig. 19—(Center) Using the Up/Down buttons, change the Thermocouple Offset.
Fig. 20—(Right) Using the Up/Down buttons, change the Heating Plate Offset.
2. Press the Up or Down button to change the temperature offset.
3. Press the Display button to save the new parameters or press the Config button
to toggle through the rest of the parameters again.
Changing Shutdown Temperature Set Point
The ATC2000 automatically goes into shutdown mode if the plate temperature
exceeds 45°C. This is designed to prevent overheating the subject.
In shutdown mode, the source temperature defaults to the temperature sensor
embedded in the heating plate. The shutdown mode has its own shutdown
temperature set point, which is different than the temperature set point in normal
mode. By default, the shutdown set point temperature is set to 37ºC. You may set it
between 20.0ºC and 45.0ºC.
To clear the shutdown mode, hold down the Up and Down buttons on the front panel
simultaneously for 2 seconds. Shutdown mode may also be cleared by momentarily
powering down the ATC2000 for 2-3 seconds. Either procedure causes the ATC2000
to revert to the normal mode. The control loop continues to reference the sensor
embedded in the heating plate, but the temperature set point is set to the set point
defined for the normal mode. To change the normal mode temperature source, see
“Setting Controlled Temperature” on page 8.
1. To change the shutdown temperature set point, press the
Config button on the
ATC2000 . The Configuration menu appears. Press the Config button again until
the Set Shutdown Temp displays.

3. Press the Display button to save the new parameters or press the Config button
to toggle through the rest of the parameters again.
