3.1.5 Analog Temperature Tuning Input

The set temperature "T
the rear panel of the TED200C. The temperature set value is proportional to the sum of the
signal at input "TUNE IN" (R1) and of the value set with the adjustment knob (F10).
The tuning range for the analog control input "TUNE IN" depends on the connected sensor:
Sensor
TH 20 K
TH 200 K
AD590/592;
LM135/335
Note
Only slow variations of the temperature set value (<< 1 Hz) are possible via the analog control
input "TUNE IN".
The actual temperature "T
OUT" (R2).

3.1.6 Analog Temperature Output

The analog output "CTL OUT"
temperature "T ". The output voltage range depends on the used temperature sensor:

TH 20 K
TH 200 K
AD590/592;
LM135/335
To the analog output "CTL OUT" any measurement equipment can be connected directly.
Devices connected to these outputs should have an input resistance of
This monitor output is convenient to use for temperature monitoring e.g. during adjustment of
PID loop parameters.
