System and Control Options

7.5.4Change 4 mA Value

For the 4 mA value, enter the smallest value for the range of the sen- sor—for example, 50°F for a temperature sensor with a range of 50°F to 90°F.

The default value for each sensor is +045.0. Values that can be entered range from -999.9 to +999.9.

To enter a new value:

•From the Setup Sensor Menu, choose 4 mA for the selected sensor and press Enter ↵ .

•To change the 4 mA value:

•Use the arrows ↑↓ to choose a character.

•Press Enter ↵ to advance to the next character position.

•When finished, press Enter ↵ again.

7.5.5Change 20 mA Value

For the 20 mA value, enter the largest value for the range of the sen- sor—for example, 90°F for a temperature sensor with a range of 50°F to 90°F.

The default value for each sensor is +096.0. Values that can be entered range from -999.9 to +999.9.

To enter a new value:

•From the Setup Sensor Menu, choose 20 mA for the selected sen- sor and press Enter ↵ .

•To change the 20 mA value:

•Use the arrows ↑↓ to choose a character.

•Press Enter ↵ to advance to the next character position.

•When finished, press Enter ↵ again.

7.5.6Change Offset Value

For the Offset value, enter an adjustment factor—for example, if the sensor reading shows 70°F when the actual temperature is 75°F, the offset might be 5°F.

The default Offset value for each sensor is +000.0. Values that can be entered range from -999.9 to +999.9.

To enter a new value:

•From the Setup Sensor Menu, choose Offset for the selected sensor and press Enter ↵ .

•To change the Offset value:

•Use the arrows ↑↓ to choose a character.

•Press Enter ↵ to advance to the next character position.

•When finished, press Enter ↵ again.
