Command

In peak hold mode, the maximum value of
the sampling period is returned as a
measured value.

Response

Measured value

When the LS-7600 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.

Reception command

Response command

When the LS-7600 Series receives command L (measured value output), the internal
timing is triggered. The LS-7600 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 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 the LS-7600 Series receives command L while the LS-7600 Series is

receiving timing input or the internal timing is triggered by command H, the
LS-7600 Series will return an error response (01).

• 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-7600 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.

• If the LS-7600 Series receives command L2 while the LS-7600 Series is

group-processing, an error response will be returned. If the LS-7600 Series
receives command L1, only the OUT1 measured value will be determined
and returned. If the LS-7600 Series receives command L0, both OUT1 and
OUT2 measured values (group processing result) with a comma as a
delimiter will be returned only when the group processing result is deter-
mined.
