3. Set the full scale value to 20 mA.

Save with the [M] button.

Adjusting full scale value

If you do not set the output current but constantly adjust it, you need to calculate the currents

to be adjusted mathematically.

To the adjust the output current of the full scale value, proceed as follows:

1. Create the reference pressure.

2. Set mode 3.

3. Adjust the output current of the full scale value to the calculated value.

4. Save with the [M] button.

Setting the full-scale value without a display

You have a device with a cover that does not have an inspection window and you wish to set

the full scale value.

To set the output current of the full scale value to 20 mA, proceed as follows:

1. Create the reference pressure.

2. Press and hold the [M] button.

3. Also press the [↑] and [↓] buttons simultaneously.

The device has set the full scale value to 20 mA.

4. When you release the buttons, the device saves the adjusted value automatically.

Setting the full-scale value without a display

You have a device with a cover that does not have an inspection window and you do not wish

to set the full scale value, but adjust it continuously.

You will need an ammeter for this purpose.

To the adjust the output current of the full scale value, proceed as follows:

1. Connect the ammeter to the test connector.

2. Create the reference pressure.

3. Press and hold the [M] button.

4. Adjust the output current of the full scale value to the calculated value using the [↑] or [↓]

button.

5. When you release the button, the device saves the adjusted value automatically.
