The following shows the timing charts when communication is performed with external devices.
Basic operation
Explanation of operations
(1) During each measuring cycle, the LEDs are lit and exposure is started.
(2) After the end of exposure, measurement starts.
(3) After the end of measurement, the judgment result is output.
(4) After the judgment result output, the analog output is updated.

Communications with External Devices Hold (peak/bottom/peak to peak/average)Explanation of operations (1) The TIMING input is turned ON.
(2) During the TIMING input minimum time, when the TIMING input is ON, sampling is started and the BUSY output is turned ON.
(3) The TIMING input is turned OFF.
(4) After the TIMING input turns OFF, sampling is ended and the judgment results are output. The BUSY output is also turned OFF.
(5) After the judgment result output, the analog output is updated.
(6) The RESET input is turned ON. If the RESET input is turned ON during the RESET input minimum time, the measured value is reset.
(7) The judgment result is reset.
(8) After the judgment result reset, the analog output is reset.
(9) The RESET input is turned OFF.
When the setting for non-measurement is "CLAMP", if the sampling value is an abnormal value or an undetermined value *, sampling is not executed. If sampling has been started, it is stopped. The output value is as follows.
• Hold the clamp value.
• To start and continue sampling even if a sampling value is an abnormal value or an undetermined value, set "KEEP"
as the non-measurement setting.
*: After the start of measurement, if measurement results are not obtained the number of times required to take the average, the measurement result is not applied.

Hold (auto peak/auto bottom/auto peak-to-peak)
Explanation of operations
(1) The peak value is updated and the judgment result is output.
(2) After the judgment result output, the analog output is updated.
(3) The RESET input is turned ON. If the RESET input is turned ON during the RESET input minimum time, the measured value is reset.
(4) The judgment result is reset.The BUSY output is turned OFF.
(5) After the judgment result reset, the analog output is reset.
(6) The RESET input is turned OFF.
(7) The BUSY output is turned ON.
When the setting for non-measurement is "CLAMP", if the sampling value is an abnormal value or an undetermined value *, sampling is not executed. If sampling has been started, it is stopped. The output value is as follows.
• Hold the clamp value.
• The BUSY signal is turned OFF.
• To start and continue sampling even if a sampling value is an abnormal value or an undetermined value, set "KEEP"
as the non-measurement setting.
*: After the start of measurement, if measurement results are not obtained the number of times required to take the average, the measurement result is not applied.
