PT 301 1
RHA M LTURPO ACF
STA STU

Characterization PROM is not
functioning correctly. Replace meter body.
#T 011P3
R ESETRECCOR ST
ST ATUS

All calibration “CORRECTS” were
deleted and data was reset to
default values.
Recalibrate transmitter.

No temperature compensation
data exists for calculations. Effect will be minor degradation of
ambient temperature influence
specifications. Replace electronics
module (PWA).

OLE I >BCRN <ESTC
OUT 1P

Transmitter’s nonvolatile memory
fault. Replace electronics module (PWA).

SPAN correction factor is outside
acceptable limits. Could be that
transmitter was in output mode.
Check input pressure and be sure it
matches calibrated range value.
Check meter body. Do a URV
CORRECT procedure.

ZERO correction factor is outside
acceptable limits. Could be that
either INPUT was incorrect or
transmitter was in output mode
during a CORRECT procedure.
Check input pressure and be sure it
matches calibrated range value.
Check meter body. Do an LRV
CORRECT procedure.

SFC failed a communications
diagnostic check. Could be an
SFC electronic problem or a faulty
or dead communication loop.
• Check polarity and try again.
• Press [STAT] and do any
corrective action required and try
again.
• Check communication loop.
• Replace SFC.

/LTSV

Either there is too much
resistance in loop (open circuit),
voltage is too low, or both.
Check polarity, wiring, and power
supply. There must be 11 volts
minimum at transmitter to permit
operation. Check for defective or
misapplied capacitive or inductive
devices (I/Ps) on the loop wiring.
