7.5.4 Change 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 4mA 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.
7.5.5 Change 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.
7.5.6 Change 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.
