Change of range adjusted with a set value

# Set range with assigned values

This function is enabled by:

- Operations -> Basic functions -> Set range with assigned values -> Set range.

Setting range adjusted with a set value (e.g. pressure) means saving a transmitter’s set value as start or end of adjusted range.
Be careful not to exceed permissible range width.

### 1. Start

After running the wizard, the main window is displayed.

Click the button Next, and the wizard will go to step 2.
If you choose Cancel, the wizard will be closed and you will return to the main window.

### 2. Setting lower range value (zero).

Change of the range start set value will cause a shift of the range end set value by the range width. So it must be remembered, that the adjusted range end must not exceed the upper limit of the basic range, otherwise the width of the adjusted range will be automatically decreased.

You should follow the wizard instructions. When current measurements and the first variable are stabilized, click the button Set zero.
In the above example, the following values will be changed: Range percentage (from 0.50 to 0.00) and Current (from 4,080 to 4,000).

Click the button Next, and the wizard will go to step 3.
If you choose Back, the wizard will come back to the previous step. Note: this will not delete the command Set zero. If you choose Cancel, the wizard will be closed and you will return to the main window.

### 3. Setting upper range value (span).

You should follow the wizard instructions. When current measurements and the first variable are stabilized, click the button Set span.
In the above example, the following values will be changed: Range percentage (from 88.15 to 100.00) and Current (from 18,030 to 20,000).

Click the button Next, and the wizard will go to step 4.
If you choose Back, the wizard will come back to the previous step. Note: this will not delete the command Set span.
If you choose Cancel, the wizard will be closed and you will return to the main window.

### 4. Final step.

A message on the operation completion will be displayed.
The button End finishes calibration.
The button Back returns to the previous step of the wizard.
If you choose Cancel, the wizard will be closed and you will return to the main window.

Change of adjusted range by entering numbers

Additional information:
Change of measuring range start and end (especially for a pressure difference transmitter with distance separators) can be performed in two ways:

- If measuring range width is known, first set the range start to zero by a command “enter numbers”, and the range end to a value equal to the range width. Next, after the transmitter installation, adjust only the range start with a set value.
- If measuring range width is not known (e.g. measurement of medium level of undetermined density) than after installation, set the transmitter’s pressure by e.g. filling the tank up to the lower, and then up to the upper level. Set start and end.
