4. When the pressure of each calibration point becomes stable and is displayed in green, record the
output value of the transmitter at each point, or use the snapshot feature.

1. Prepare
Open the pressure output area of main operation interface: High-pressure or low-pressure range
(depends on the range of the transmitter).
Switch the electrical measurement item of main operation interface to: Current measurement
2. Connection
Connect the transmitter as shown in Figure 3-17; connect the electric circuit as shown in Figure
3-10, 3-11, 3-12 or 3-13.
3. Establish connection (see Section 3.3.1). During setup, switch the process quantity to current
output.
4. Press the setup icon, to set the parameters of the HART transmitter (see Section 3.3.3).
5. Press the setup icon, to maintain the process quantities of the HART transmitter (see Section
3.3.3).
6. Manually set or use the step function (see Section 3.2.1 "Auto step and manual step of pressure
output") to output the pressure of each calibration point.
