Timing Chart
The following timing chart applies to timing input and RS-232C data output (the meas-
uring mode is not set to sample hold 2 or self-timing hold.)
TIMING input
Measured value
3.5ms
RS-232C data output
ON
OFF
If the measuring mode is set to normal, auto peak hold, auto bottom hold, or auto
peak-to-peak hold, the measured value will be transmitted at the moment timing input
is turned ON.
The measured value will be output when timing input turns ON if the measuring mode
is set to peak hold, bottom hold, peak-to-peak average hold, or sample hold 1.
If the measuring mode is set to sample hold 2, the following timing chart will apply.
TIMING input
Measured value
Sampling period + 3.5 ms
RS-232C data output
ON
OFF
The measured value will be output when sampling period plus 3.5 ms elapses after
timing input turns ON. Refer to page 4-39 for the sampling period in detail.
If the measuring mode is set to self-timing hold, the measured value will be transmit-
ted when the measured value is determined.
Note: If both OUT1 and OUT2 are set to sample hold 2 or either of them is set to
sample hold 2 while SYNC is set as a T-MODE option setting, measured
values will be determined asynchronously. At that time, if timing input turns
ON, both OUT1 and OUT2 measured values with a comma and a delimiter
will be returned when the OUT1 and OUT2 measured values are determined.
