DIGITAL OUTPUT
1. Asynchronous RS232 port, 8 bit data, 1 stop bit, no parity control.
2. Transmission rate (default) - 115 kBod (repetition rate ~ 1.2 kHz ). Factory fitted option: - 38 kBod (repetition rate ~ 0.3 kHz ).
3. LSB = 0.298μV.
4. Additional data (X data) - temperature (taken from AD TMP36), supply voltage, consumption current. These data (16 bits each) are transmitted in series of 16 sendings according to the status of COUNTER.
