Command
In peak hold mode, the maximum value of
the sampling period is returned as a
measured value.
Response
Measured value
When the LS-7000 Series receives command L (measured value output), the internal
timing is triggered and the determined measured value will be returned. The timing ON
command (command H) is not required. The timing OFF command (command U) is
required to start sampling.

Command
The measured value will be returned
after the sampling period.
Response
Measured value
When the LS-7000 Series receives command L (measured value output), the internal
timing is triggered. The LS-7000 Series will start sampling and the determined meas-
ured value will be returned. The timing OFF command (command U) or timing ON
command (command H) is not required.
Note: • If the LS-7000 Series receives command L while the LS-7000 Series is
receiving timing input or the internal timing is triggered by command H, the
LS-7000 Series will return an error response (01).
• If the measuring mode is set to self-timing hold, command L will not be
available. Error (99) will be returned if this command is executed.
• If both OUT1 and OUT2 are set to sample hold 2 or either of them is set to
sample hold 2, measured values will be determined asynchronously. At that
time, if the LS-7000 Series receives command L0, the response will not be
returned asynchronously. Instead, both OUT1 and OUT2 measured values
with a comma as a delimiter will be returned when the OUT1 and OUT2
measured values are determined.
