make offset/gain setting in the device test of GX Developer.
Perform mode switching by making the setting of the mode switching setting (buffer
memory addresses 158, 159: Un\G158, Un\G159) and turning Operation Condition
Setting Request (Y9) from OFF to ON.
Note that if module control is resumed without offset/gain setting being made,
operation will be performed with the default values.
