I have two ECDs in one instrument. When I turn the detector heaters off, one signal dips a little bit and holds steady (a change from about 30 mV at 350C to about 25mV at room temp).
The signal from the other detector, though, actually increases. At 350C, it was showing 25 mV. At 120C, it was about 180 mV. If I hold the temperature there, the signal holds. If I turn the heater off, the signal gradually rises until it's at about 250 mV at room temperature.
Any thoughts?
