Information
Excess Zero
Correction
The DP and/or SP
pressure Zero
calibration or LRV
correction performed
by the user is
excessive for the
given inputs.
Perform a Reset
Corrects on the DP
and/or SP Pressure
Calibration to reset
the User calibration to
factory default. If
required, repeat the
Pressure calibrations
being careful to
ensure that input
during
Zero calibration (Input
Correct) is at zero
pressure and input
during LRV
calibration
(LRV Correct)
matches the
configured
pressure LRV value

Excess Span
Correction
The DP and/or SP
pressure URV
correction performed
by the user is
excessive for the
given inputs
Perform a Reset
Corrects on the DP
and/or SP Pressure
Calibration to reset
the User calibration to
factory default. If
required, repeat the
Pressure calibrations
being careful to
ensure that input
during
URV calibration (URV
Correct) matches
the configured
pressure URV value.
Bit -1
Char Calc Error
The redundant
integrity check on the
Pressure
measurement
calculation
indicates a failure.
Power Cycle the
device. If the problem
persists,replace the
Pressure module.
Bit - 2
Sensor Overload
The Meter Body is
sensing Differential
or Static pressure
greater than the
specified limit of the
Upper Range Limit
(DP URL)
Check that the
process inputs are
within
specification for the
Differential and Static
Pressure for this
device input
range. Correct the
excessive pressure
input. If higher
pressures are
required, a
higher range device
type may be
required. Meter Body
may have been
damaged.
