Procedures
Transmit the command data for span mV/V
value change from the host, and set the output
value from the load cell corresponding to the
value set in step 3.
The display in the load display section displays
“−RS−” and “ZERO” alternately.

 When the inspection data sheet of the load
cell indicates only the digit of “X.XXXX”,
put “0” for the extra digit. The numeric
value of an extra digit, etc., is
automatically rewritten as the
compensated value after executing the
tare weight compensation or the fine
adjustment of the load. Though the
setting range of the load cell is from 0.200
0 mV/V to 3.100 0 mV/V, the range of the
actual setting value is “02000 to 31000”
because the decimal point is not added.
 Don’t attach the decimal point to the
setting value in the command data.
 The setting value in the command data is
put from the right, and an unnecessary
space is given as space.

Set the initial load condition.
Transmit the start command for “Calibration
method to register the output of strain gage
applied transducer at the time of maximum
display after setting the load to zero.” from the
host. The return signal is transmitted from this
instrument and the zero adjustment is started.

 Warning ： At the same time, take care not
to apply load variation due to vibration and
so on. When load variation is applied, there
will be possibilities that zero point is
unstable, and precise reading of zero will
not be obtained.
