Calibration
For maximum of accuracy when using “Cage Feedback Mode”, H20
1-T-UNIT-BL allows to calibrate the
system in your lab at your Room Temperature. To do so, read the paragraph 9 and then follow the instruction
below:
1.
Press on the
Calibration
icon
(see Figure 28 a)
2.
Press the
Adjust
button when the sample temperature is stable, as shown in Figure 28 b; the system will
calculate the offset value to apply to the Cage Temperature to have the sample at the desired temperature.

Tip
►
Make sure the temperature values are stable before starting the cage calibration as suggested in
dialog opening when pressing “Adjust”
(see Figure 29).

Digital Input
Digital Input feature is available only for TTL ready (optional) controller.
TTL feature allows to change setpoint between two specified values using a TTL signal (see Figure 30 b).
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.
Press on the
Digital Input
icon
to enable digital input feature, as shown in Figure 30 a and b.
