1.- Output calculation:

Resolution = 20 − Zero .

F. scale - offset

Offset & f. scale = defined by the

user

Zero = 0 mA or 4 mA

MA = (( F. scale - offset ) x Resolution) + Zero

MV = mA x ohms

(100 ohms)

= mA x 100

- Maximum load is:

CVM-BD-420-4: ................400 Ω

CVM-BD-420-8: ................300 Ω

- The maximum allowable offset is a value equal to the 90% of the full scale.
