HART
Loop Test [475 key sequence 1, 2, 2]
Loop Test is used to verify the 4-20mA current output of the AutoXP MVT.
The associated method will automatically run and can supply any required mA
value from between 4 and 20mA so that the current loop can be verified when
connecting to a host device.
1. After selection of the required input for calibration a warning is provided to
remove the AutoXP MVT output from any automatic control.
Figure 4-10. Warning to remove MVT output from automatic control
2. Select required output to force onto the 4-20mA loop:
If 4mA or 20mA selected, go to step 4 below.
If Other selected, go to step 3 below.
If End selected, Loop T est is exited. Go to step 6 below.
