47LLC OPERATING MANUAL EM-9505-B Rev.4
IMPORTANT
Both normal scaling (display scaling value A < display scaling value B) and inverted scaling (display scaling value A >
display scaling value B) can be set within the range of -19999 to 19999.

RELATION BETWEEN INPUT sCALING AND DIsPLAY sCALING
The relation between input scaling and display scaling is as shown in the following figure.
e.g. To display 0 – 10 mV DC input as 0.0 – 300.0 kg

PROCEDURE TO sET sCALING VALUEs
•
Flow in setting scaling values
6-step settings are necessary to set scaling values.
To set the input scaling values A and B, actual input signals are used. It is necessary to apply load to (a) strain gauge(s) of
the equipment or device on site. You can set the display scaling values A and B, and the decimal point position first, and
then set the input scaling values A and B, applying load to the strain gauge(s).
•
Operating procedure to set scaling values
Following pages describe operating procedures in each step to set the input scaling to 0 – 10 mV, and the display scaling
to 0.0 – 300.0 kg without the rated load applied but with a weight 30 kg, 10% of the load as an example.
NOTE
A parameter “Tare adjustment” is indicated between STEPS 5 and 6. Check function indicators to set each parameter
correctly.
