calibration
If signals are applied as shown, then
• IN1 (A) starts a zero calibration (Z1)
• the detection window (300 - 500 ms after edge) for IN2 (B) begins while the zero calibration (Z1) is ongoing: Signal
(B) is ignored
• the edge of IN1 (C) is detected and the associated zero calibration (Z2) is started
• the detection window (300 - 500 ms after edge) for IN2 (D) begins after the zero calibration (Z2) has ended, so
the span calibration (S1) is started
• the span calibration (S1) is canceled by the falling edge of IN3 (E)
Examples
The sequences shown in Fig. 7.8 are based on the following setup for digital inputs IN1 to IN3:
• IN1 starts a zero calibration, initiated by a rising edge
• IN2 starts a span calibration, initiated by a rising edge
• IN3 cancels all calibrations with its falling edge
