１６．Connection diagram for BCD output (Option:B)
1.
The Binary Coded Decimal code is the NPN opening collector pulse output. In addition,
it becomes all figure parallel output.
2. The output of data becomes the output for a measurement chosen by a measurement
operation method.
I output it in sync with a measurement.
（It is not output by the indication of the hold state.）
3. The output logic of data is modifiable. （Please refer to P.32 Mode No. E）
Output logic (positive) ：The state that an emitter does conduction with the collector of
the output transistor when data output it
Output logic (negative)：The state that an emitter does not conduction with the collector
of the output transistor when data output it
4. When I take in data because TI (take-up inhibition)signal is output at the time of data update,
TI signal please go at the time of OFF.
The logic of the TI signal is modifiable, too. （Please refer to P.32 Mode No. E）
