1 Cannot be specified for the electromagnetic relay type (Type suffix code -T1) or low withstand
voltage relay type (Type suffix code -L1) analog input module.
2 Appears when Calculation is set to Delta.
3 Appears for AI (mA) channels.
4 Does not appear for AI (mA) channels.
5 Appears on models with the log scale (/LG) option when the range type is Volt.
6 The default values of AI (mA) channels are GS for Type, 4.000 for Span Lower, 20.000 for Span
Upper, and Linear scaling for Calculation.
7 Appears for 4-wire RTD/resistance type channels
