Setting the start-of-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 start of scale value.
To set the output current of the start of scale value to 4 mA, proceed as follows:
1. Create the reference pressure.
2. Press the [↑] and [↓] buttons simultaneously.
The device has set the start of scale value to 4 mA.
3. When you release the buttons, the device saves the adjusted value automatically.
Setting the start-of-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 start of scale value, but adjust it.
You will need an ammeter for this purpose.
To the adjust the output current of the start of scale value, proceed as follows:
1. Connect the ammeter to the test connector.
2. Create the reference pressure.
3. Adjust the output current of the start of scale value using the [↑] or [↓] button.
4. When you release the button, the device saves the adjusted value automatically.
6.5.3.3 Setting/adjusting the full scale value
Introduction
Set or adjust the full scale value of the pressure transmitter in mode 3.
You can also adjust the start of scale value or the full scale value separately as well as adjust
both these values one after the other.
Condition
You are familiar with the correct operation of the transmitter and the associated safety notes.
You have selected a reference pressure that corresponds to the full scale value and is within
the permissible tolerance range.
The transmitter is in "Pressure" measuring mode.
Setting 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. Set mode 3.
