5.5 Current Loop Test
Both current loop outputs can be automatically stepped through the 4-20mA range for test purposes. When the
loop test command is sent both loops are set to 4mA for a duration of 5 seconds. After 5s the loop current steps
by 2mA to 6mA. This process is repeated until the 20mA level is reached whereupon both loops return to the
wind measurement mode.
The current loop outputs during the test are shown in Figure 25.
