The transmitter has a built-in software function for testing analog outputs. To test the outputs:
  1. Make sure the transmitter is not in adjustment mode (see Calibration and adjustment overview).
  2. Press the + adjustment button (see Figure 1).
    This sets the output voltage level to the high point of the analog output range (for example 10 V). The output stays at this level for about 30 seconds after the + adjustment button has been pressed.
  3. Press the - adjustment button.
    This sets the output voltage level to the low point of the analog output range (for example 0 V). The output stays at this level for about 30 seconds after the - adjustment button has been pressed.
