Symptom Response
Reading seems to always be
high by a fixed amount
Refer to the Device Parameters manual for
“Adjusting Analyzer Reading to Match Spe -
cific Standard(s)” .
Capture diagnostic data and send the file to
Hauser (refer to “To read diagnostic
data with HyperTerminal” in the Device
Parameters manual).
Reading is erratic or seems
incorrect

Reading goes to full scale If 4–20 mA Alarm Action is set to 1 , look on
display for a fault message (refer to the Device
Parameters manual for instruction on system
faults and “To change parameters in Mode
2” ).
Gas concentration is greater than or equal to full
scale value.
Reading goes to “0” If 4–20 mA Alarm Action is set to 0 , look on
display for a fault message (refer to the Device
Parameters manual for instruction on system
faults and “To change parameters in Mode
2” ).
Gas concentration is equal to zero.
Serial output is providing no
data
Make sure the computer COM port is set for
19200 baud, 8 data bits, 1 stop bit, no parity,
and no flow control.
Be sure no other programs are using the COM
port selected.
Make sure the connections are good. Verify the
correct pin connections with an ohmmeter.
Make sure to select the correct COM port into
which the cable is plugged.
