Action of continuous sampling (without HOLD input)
HOLD input
400 s or more
VALID output
Keep the HOLD input at the high level to output the measurement data for each
sampling period.
After data output is set, the VALID output becomes Low (ON).
Action with HOLD input
HOLD input
50 s
VALID output
If the VALID output is Low (ON), the BCD data is output after 400 s or more
since the falling edge of the HOLD input, and it remains output while the VALID
output is Low (ON).
If the VALID output is High (OFF) and the HOLD input is Low (ON), the BCD
data output is maintained after the VALID output has become Low (ON).
The VALID output becomes High (OFF) after approx. 400 s or more since the
HOLD input becomes High (OFF).
If the HOLD input remains High (OFF), continuous sampling at a sampling
period of 50 s occurs.
Note: If the BCD output is valid, the sampling period of the GP-X controller
becomes 50 s (sampling frequency: 20kHz).
If the BCD output is valid, the analog voltage output is invalid.
