#155970 - You would have to measure! Responding to: ???'s previous message |
Bill Johnson said:
I've thought about trying to compensate for the drift in software, but a reset could happen at any time and the system would not know how long the power had been applied, and thus where it was at on the drift curve. Obviously the time taken to heat up would depend on the ambient temperature, any draughts, etc, etc - so simply working by time would be useless! You'd have to measure the temperature. But, if this transformer really is supposed to be designed for this application, that really shouldn't be necessary! |
