Timeout Time 1
If the DSA signal does not turn ON
within the specified time after
measurements are completed, a
timeout error will occur.
1
Turn ON the TRIG signal while the BUSY signal is OFF.
2
Measurement begins and the BUSY signal is turned ON during the measurement process.
3
At the same time or after the TRIG signal turns ON, the external device turns ON the DSA signal
to request data transmission.
*1 If you do not turn ON the DSA signal within the specified timeout time after measurements are completed, a timeout error will occur. (This
is timeout time 1.)
4
When the measurement has been finished, the measurement result is output using an OR signal,
and the BUSY signal is turned OFF.
*2 You can also set the [BUSY output] parameter so that the BUSY signal is turned OFF after the completion of data logging, image logging,
or displaying results.
5
The DSA signal is ON, and thus the D0 to D15 signals are output and the GATE signal turns ON.
6
When the DSA signal is turned OFF, the GATE signal turns OFF.
*3 If you do not turn OFF the DSA signal within the specified timeout time after the GATE signal turns ON, a timeout error will occur. (This is
timeout time 2.)
7
If more than one data item is being output for one measurement and you do not turn ON the DSA
signal within the specified timeout time after the GATE signal turns OFF, a timeout error will oc-
cur. (This is timeout time 3.)

If more than one data item is being output for one
measurement and the DSA signal does not turn
ON within the specified time after the GATE
signal turns OFF, a timeout error will occur.
Timeout Time 2
If the DSA signal does not turn OFF within the specified time
after the GATE signal turns ON, a timeout error will occur.
