9.5.4 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 -999.9. 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.
9.5.5 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 +999.9. 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.
9.5.6 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.
