For easy testing and adjustment, reference signals are provided for the 2 output channels. For instance, by inserting a jumper plug, an output can be forced to the full scale or zero level. A readout device can be easily adjusted to comply with the transmitter output. Inside the transmitter box, there is a label showing all the useful jumper combinations for output scale, measurement range, and testing.
