4.5.6 Function 6: Display CA and AO value
4.5.7 Function 7: Fixed loop analog current test, AO calibration
Operation method:
a. As figure 4-5-6-1, press to HART function 6.
b. As figure 4-5-6-2, press to display CA value and AO value. (The units remain unchanged)
press to the interface as figure 4-5-6-1; Press to function 7.
This test is to appoint to the fixed loop current analog output of AO value. The can supply analog current of 4 mA,
12 mA and 20 mA. This function can be used to determine the accuracy of a transmitter's output current. If accuracy is
unqualified, please start AO calibration as following:
