10.1.2 Warning messages
Important Note: The value in the right hand column of the above table is a direct correlation to
the value in the warning flag column in the measurement file Result.txt. If a value in the warning
flag column does not exist in the above table it is because it is a composite code meaning more
than one warning is relevant (e.g. a value of 6 in the warning flag column equates to warning
messages 4 and 2 from the table above). Be aware that this is a hexadecimal code meaning that
if warning codes 8 and 2 from the above table are relevant, it will be displayed as an A in the
warning flag column of the measurement file. If you have any difficulties relating the
measurement file warning flags to the codes in the above table, please contact your Hach Lange
representative for assistance.

HEX001
W1: Unstable reference
pressure. The variation of reference
pressure is too high. Check the pressure stability of
the input reference gas.
1
HEX002 W2: Unmatched package size.
The measured package height is
different from the value defined in
the package definition.
Check the package size
definition.
2
HEX004
W4: Measurement timeout.
Accuracy of dissolved O2 not
guaranteed.
The measurement pressure is
lower than 3.5 bar.
Check the black seal on the
piercing unit.
4
Check the purge gas pressure.
Check the forcing gas pressure.
Check the Goretex filter.
Gas path not airtight.
Check the airtightness of the gas
path between the piercing unit
and the measurement chamber.
HEX010 N/A
A spontaneous and/or too fast
degassing has occurred. Restart the measurement with
another package.
10
The package (especially in the
case of cans) is losing pressure
due to a leak.
Verify the package is leak free i.e.
watertight and airtight
The sensor has become
unstable. Perform an oxygen sensor
maintenance procedure
HEX020
W20: Measurement process
incomplete. Insufficient initial
package pressure. The pressure in the package is
too low to continue with a
measurement.
Restart the measurement with
another package.
20
HEX040 W40: Spontaneous degassing...
A spontaneous degassing is
detected at the end of the first
expansion.
Restart the measurement with
another package.
40
HEX080
W80: Measurement process
incomplete. Insufficient package
pressure during ultrasound
stage.
The measured pressure is too
low to compute the second phase
of the measurement.
Check foam intrusion in the gas
path.
80
Check Goretex filter.
HEX100 N/A
Possible problem with instrument
configuration
Contact your Hach Lange
representative to analyze the
problem.

HEX200 N/A
Possible problem with instrument
configuration
Contact your Hach Lange
representative to analyze the
problem.

HEX400 N/A
True CO2 may not be reliable
due to CO2 purge gas purity out
of specification. Check gas cylinder purity, tubing
and connections to 6110 and
recalibrate CO2 sensor
