Burst Command Set burst command
Alarm State Read only
Note: The temperature transmitter can provide additional setting items such as sensor type, wires, sensor status, CJC type and
value according to the function supported by the transmitter.
3.4.3 Process variables
In the HART page choose electrical measurement, click icon and choose Process variables, it can show process
variables, output current, percentage, second variable, third variable and loop current. Among these, the units of second
and third variable depend on different devices.
3.4.4 Diagnosis/ Service
1. Current loop test

Click the icon to select Diagnosis/ Service and enter the current loop test. Carry out the current loop test, the
value range of this parameter is (4-20) mA.

The HART measurement value at the top of the calibrator page is the real value of the current loop.
2. Zeroing (only for pressure transmitter)

Select zeroing in the HART Diagnosis/ Service interface to enter the zeroing interface.

Ensure that the current measured value is close enough to the zero point, otherwise it may cause zero failure.
3. Current Adjustment

By adjusting the scaling coefficient of current output of the transmitter, the output current value of the transmitter
will keep the same as the actual loop current output value.

It provides adjustment of D/A zero point (4mA) and D/A full scale (20mA): press the screen to get the value for
adjustment.
