Selecting the outputs

The HMP140A series transmitters can be ordered with the desired output
signals already selected. If the outputs are changed, the jumpers have to be
moved to corresponding places (see Figure 3.5). For current outputs, see
Appendix 1. Jumper changes may change the output <

0.15 %FS within the

chosen range; this usually does not give cause to recalibration.
