6.2.1.5 External Sensors
There are two external temperature sensors connected to the T-Unit. A white thermistor is to be placed in
air to monitor the Room Temperature. A green Fine Gauge Thermocouple, to be placed into a reference
well if running the “Sample Control Mode” or to run Chamber or Objective Heater calibrations . IMPORTANT:
when running the Temperature Control in Sample Feedback Mode the green Fine Gauge Thermocouple
MUST be immersed in liquid in a Reference Well. Failure to do so will result in overheating of the
chamber. When running in “Chamber Feedback Mode” the green Fine Gauge Thermocouple can be placed
in any area of the system to monitor temperature in that area. With this setup you can monitor both
temperatures read by the thermistor (T Room) and by the thermocouple (Free Sensor) (see Figure 42).

6.2.1.6 Digital Input
Digital Input feature is available only for TTL ready (optional) controller.
TTL feature allows changing setpoint between two specified values using a TTL signal. The TTL is a digital
input for our Units and has only two values: High and Low. The setpoint values for High TTL value and for
Low TTL value can be set using OKO-TOUCH, via GPIO connector.
When TTL Control is enabled, the user cannot change the setpoint using the dialog in the main page. In this
case, the setpoint value is read by the external TTL signal.
