Digital Gauge Frequently Asked Questions
Question number FAQ-0044
Please tell me about the update timing of the BCD output of the gauge counter.
Ono Sokki The timing when the digital gauge counter updates the BCD output can be broadly divided into two types.
1. DG-4320/4340, DG-5100 (BCD output is an optional feature) and DG-4140 (discontinued and displayed item)
BCD output updates the values at regular time intervals.

If the counter's count value does not change, the BCD output data is retained.
(Data is not output only during updates, nor does the signal drop with each update)
In the DG-4140, the output update time interval is 25 ms, but it has been shortened to 10 ms in the DG-4320/4340 DG-5100.
2. DG-4120/4240/4280 (discontinued and displayed item)
BCD output updates the value when there is a change in the measured value.

The BCD output of the DG-4120/4240/4280 is linked to the internal counter, so it updates almost at the same timing as the counter's count value changes. The delay time is approximately 20 μs.
