Chapter 5 Function Reference
Display Precision
Set how many decimal places are displayed for the process value and associated parameters
such as set points.
Options:
Whole, Tenths, Hundredths, Thousandths
Calibration Offset
Set a value to add to the measured input value to compensate for sensor placement, lead
wire resistance or other factors that cause the input to vary from the actual process value.
Range: -99,999.000 to 99,999.000°F or units
-55,555 to 55,555°C
Filter
Set the amount of filtering to apply to the in-
put. Filtering smooths signal fluctuations. In-
crease the time to increase filtering. Excessive
filtering slows the input’s response.
Range: 0.0 to 60.0 seconds
Input Error Latching
Set whether an input error persists until it is
cleared or clears automatically when the sensor signal returns to a normal level.
Options:
• Off
: error clears automatically once the input returns to normal.
• On
: error remains active until the input returns to normal and the error is cleared by
the Clear Error parameter.
Clear Error
Set this parameter to
Clear
to reset the input error after correcting the condition that caused
it.
Options:
Ignore, Clear
