(2) Operation
◆ In the HART settings interface, you can view the HART parameter values in real time
◆ After inputting the setting status of the current option, click to save
，
click to cancel saving and
return;
◆ If the input value is displayed in red when saving, it means the input value is not accepted, please check its
input range;
◆ If the current setting is canceled or the setting fails, the current item is restored.
5. Service
(1) Current loop test
◆ Click to select diagnosis/service, enter the current loop test, and perform the current loop test. The value
range of this parameter is (4-20) mA;
◆ The HART measurement value at the top of the calibrator interface is the actual value of the current loop.
(2) PV zeroing
◆ Select zeroing in the HART diagnosis/maintenance interface, and enter the zeroing interface;
◆ Ensure that the current measurement value is close enough to the zero point, otherwise it may cause zeroing
failure.
(3) Current adjustment
◆ By adjusting the proportional coefficient of the current output link of the transmitter, the AO value of the
