Jumper positions for selecting working mode

PCD2.W340 only; on the other module types the working modes are fixed

All inputs set for temperature (position T) must be wired. All unused inputs (with the

W340) must be adjusted to current range ‘C’ or voltage range ‘V’.

Changing the jumpers

On this circuit board there are components that are sensitive to electrostatic

discharges. For further information, refer to Appendix B, “Icons”.
