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.

The following command format will be used if ASYNC is set as a T-MODE option set-
ting.
