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 adjustment is needed, set the polling address to 0 in the HART settings.
1. Loop test
The current loop test allows users to compare and calibrate the current output signal of the transmitter and the current
measurement signal of the device. During the test, the user can input the current measurement signal value of the device
through the numeric keyboard or click the button of the specific current value at the bottom of the interface. After that, the
device will send the applied current value to the transmitter and display the output current value of the transmitter and the
actual current measurement value of the device on the interface. Compare the two; if the value deviation is large, it
means the transmitter needs to be calibrated / adjusted.
