Vaisala Indigo200 - Analog Output Adjustment Example; Table 4 Transmitter Analog Channel Fixed Test Output Levels

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 4
(page 44).
Table 4 Transmitter analog channel fixed test output levels
Current and voltage test output points Fixed test output level
Low point test output for current output 4 mA
High point test output for current output 20 mA
Low point test output for voltage output 1 V
High point test output for voltage output 10 V
For adjustment instructions, see Analog output adjustment example (page 44).
Always switch the Insight analog output adjustment mode o after
testing or adjusting to return the output to normal operating mode. Normal
measurement data output is not available in adjustment mode.
