♦ 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.

37

3. Current Adjustment

♦ By adjusting the scaling coefficient of current output of the transmitter, the output current value of the transmitter will

maintain 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.

4. Sensor adjustment

♦ The Sensor adjustment is used to adjust the PV of the transmitter, usually including one or two adjustment points

(lower point and upper point). Some transmitters do not support this function (please refer to the transmitter's

manual).
♦ Lower point adjustment
(1) First, provide the external standard source to the transmitter manually. After stabilized, input the standard source

display value directly by the number keys; For the pressure transmitter, the standard source display value can be

directly obtained through the external pressure module. In this case, click the Get icon on the calibration page to

get the standard value of the pressure module directly.

38

Note: For some transmitters, it is not necessary to input the adjustment value, the transmitter automatically uses the upper and

lower limits of the range (the lower limit of the range corresponds to the lower point adjustment value, and the upper limit of the range
corresponds to the upper point adjustment value) as the adjustment value. In this case, just input any value;

(2) Execute the Trim command. After that, the PV value will change according to the trimmed point value.
♦ Upper point adjustment
Same as the lower point adjustment.
♦ Single point adjustment
Same as the lower point adjustment.
♦ Restore to factory setting

After selecting "Restore Factory", a dialog box will appear "Are you sure you want to perform this operation?", click

OK to continue. After that, the transmitter's lower and upper point values will be restored to the factory settings.

Note: The current loop test and D/A adjustment is only available when the transmitter address is 0.
Note: The sensor adjustment provides corresponding support items according to the transmitter function.
Note: If the HART transmitter used does not have all the above functions, contact the manufacturer.

3.5.8 Ramp output

The three electrical settings of voltage, current, and frequency of the calibrator, and the two simulate temperature

output options of, simulate thermocouple and simulate thermal resistance, all support automatic ramp output mode. The

Ramp can increase or decrease the output value smoothly and continuously. In fact, a small step value is used to form a

Ramp signal, which is represented by a Ramp gradient in the calibrator. The calibrator will automatically calculate the

Ramp gradient according to the start and end values of the Ramp and the rise and fall time. When the start value and

end values are fixed, the longer the ramp time, the slower the ramp output and the smaller the ramp gradient.

A complete ramp output stroke includes an up stroke (from the start value ramp to the end value) and a down stroke

(from the end value ramp to the start value), when the rise time and fall time are the same, the actual output points of the

up stroke and the down stroke are symmetrical one by one. Click icon to select ramp output and go to the settings,
