Only with CP it is not less than 2 Crad where in the manual is 1-30 Crad.
The wiring diagram is not the best.
3 + 4 = Power supply
1 + 4 = lamp or consumers
Set 2 + 3 = Bridge
5 + 6 = probe
Then the menu only adjust to the temperature at which it go out and tackle. Then, the difference and yet the OBS mode for heating or cooling should be.
For me it was now 24 days of continuous operation. It has often switched and so far everything is working yet. For me it had to run a 230 Volt 40 Watt bulb. She had to bring to a temperature of 39 Crad the incubator interior. This one can put it only on a differential of 2 Crad I had to set it to 40 Crad. Thus, at 38 went Crad and 40 Crad from. What then but not a problem, because I really a temperature of 38.6 Crad needed.
The display accuracy is ok, about 0.5 Crad deviation from a calibrated thermometer.
Conclusion:
Pro:
0.1 Crad digits
small size
favorable
Cons:
no German instruction
Differnez only 2-30 Crad set not as described 1-30 Crad
Always reset a mistake while entering.
No 0.1 Crad steps adjustable.
