1

Current to engineering value

Convert a measured loop current.

Engineering value50.00 %Within calibrated range
2

Engineering value to current

Calculate a loop-current setpoint.

Required loop current12.00 mAWithin calibrated range
EU = LRV + ((mA − 4) ÷ 16) × (URV − LRV)mA = 4 + ((EU − LRV) ÷ (URV − LRV)) × 16
