The general fluctuation is expected, but the SHAPE of the curve is consistent only with a TRIANGULAR 150-sec rise, 150-sec fall (or possibly sawtooth) wave. It is NOT consistent with a DC offset applied either through the heater or the central reactor cylinder. (I have to check what a triangle applied to the heater would look like. I guess I should also try a 1/450 hz sine wave).
