The “

” marks indicate the most typical selection for each specification.

*1:

Users must consider the characteristics of selected wetted parts material and influence of process fluids. Specifying
inappropriate materials has the potential to cause serious damage to human body and plant facilities resulted from an
unexpected leak of the corrosive process fluids.

*2:

For External Temperature Input code 0 (Fixed temperature) .

*3:

Recommended External Temperature Input Cable is as shown in Table 6. RTD is not provided.

*4:

Specify when using conduit for RTD connection.

*5:

Preset external temperature value is used for density compensation.

*6:

Not applicable for output signal code -F and option code /KS2.
