- During the Calibration phase, the current output for the transmitter, will increase around 7mA.That’s an immediate variation only visible during the Calibration phase; it won’t have any effects on the final signal.- Switching off the supply while the calibration function is activated, could be cause of calibration problems; the transmitter can be recalibrated to the initial value by activating the “partial reset function”.- The Calibration function is not allowed for “external Autozero” version.
