Warning ● By feeding ON the instrument with external HOLD signal shorted ,
the output of RS−422 Interface will be as follows:
1
Even when the Display is targeted for HOLD with the FUNC−50,
the load weighing data will become only spaces at the time of
reading−out command for load weighing data is executed.
2
When the option is targeted for HOLD with the FUNC−50, the
load weighing data will become all spaces at the time of
reading−out command for load weighing data is executed.
3
Other than the case above ① and ②, selected load value will be
outputted.
● When the CHECK switch is applied, pay attention to the following
points.
1
By ON operation of CHECK, the instrument isn’t in Measurement
