10-3-3. Equivalent Circuit (Output)
The signal output circuit is open-collecter output of TTL.
10-3-4. BCD Data Output
Measured weight values are output in 5-digit BCD. Respective digits are output as 0 and 1 data in 4
bits: 8, 4, 2 and 1.
10-3-5. Polarity Output (MINUS)
The polarity of weight values output as BCD data is output as follows:
When positive (+): 0
When negative (-): 1
