I have a LakeShore 336 temperature controller. Analog outputs 3 and 4 cannot power heaters directly so I'm planning to use an external power supply to use outputs 3 and 4 to power heaters. I want to use close loop PID in order to control the heaters based on temperature sensor inputs. However, the manual in confusing me because:
At page 10, section 1.3.4.2, it mentions that outputs 3 and 4 have the following modes:
1. Close loop PID
2. PID Zones
3. Warm up heater mode
4. Manual output
5. Monitor out
The manual at page 70 mentions the modes to be:
1. Open loop
2. Warm up supply (which I assume is the same as warm up heater mode)
3. Monitor out
The question is, can I use outputs 3 and 4 to control heaters in a close-loop PID mode using an external power supply (unipolar)?
