To show the ongoing calibration process, A or B (depending on the channel) is blinking in the display.
PAGE 45
Transmitter M400/2(X)H, M400G/2XH 45 The user can now enter Point 1. The offset calibration factor is calculated by using the value of Point1 instead of the measured value (line 4, mV = ....) and displayed on the next screen. Z is the newly calculated offset calibration factor. The slope calibration factor S is always 1 and does not enter the calculation. After a successful calibration, the calibration values are taken over (Adjust) or discarded (Calibrate) or (Abort).
