  • Page 37 as a calibration target are available only when the polling address of the transmitter is 0. These functions cannot be completed in multi-point access mode (when the searching/polling address is 1~15). That is because the current output is fixed at around 4mA under this mode. If the user needs to adjust, they must set the polling address to 0 in the HART settings.

Under the zeroing mode, please select the pressure module connected to the device as the standard module. Then the upper channel in the interface displays the pressure value output by the transmitter, and the lower channel displays the pressure value measured by the selected standard module of the machine.

D/A Adjustment By adjusting the current output of the HART transmitter, the zero point (4mA) and full scale (20mA) output values of the transmitter PVAO are consistent with the actual output loop current value. Take D/A zero calibration as an example. After entering this calibration mode, the upper channel of the interface displays the current signal value actually measured by the calibrator (ADT226/227), the lower channel displays the current value of PVAO zero point, which is fixed at 4 mA.
