7.3.3 Analog output adjustment
If the analog output appears to be inaccurate, you can test and adjust the output level in the
Devices > Calibrate / Adjust menu of the Indigo80 handheld indicator. Note that each of the 3
analog output channels is adjusted separately. To carry out the adjustment, you need a
multimeter (or an alternative method for reading the analog output level) to verify the
transmitter test output level.
During the adjustment, the output of the transmitter's analog output channels is forced to a
fixed current or voltage level. The adjustment is a 2-point adjustment with a low point test
output and a high point test output: the fixed test output levels are listed in Table 6 (page 50) .
