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.
