Note: Any calibration being calculated when an error occurs, is discarded. The old
calibration is kept.
Table 3 Error codes
Error Description Solution
ERR01 The turbidity of the
dilution water is greater
than 0.5 NTU.
Start the calibration again with lower turbidity
dilution water.
Note: Ignore ERR01 when the sample cell diameter
is less than 25 mm. Push UNITS/Exit to go back to
measurement mode.
ERR02
• Two calibration
standards have the
same value.
• The difference
between two
calibration standards
is less than
60.0 NTU.
• The turbidity of
Standard 1 is too
low (less than
10 NTU).
1. Inspect the preparation of standards.
2. Do the calibration again.
Note: Ignore ERR02 when the sample cell diameter
is less than 25 mm. Push UNITS/Exit to go back to
measurement mode.
ERR03 Low light error
1. Put the sample in the instrument again.
2. Make sure that the lamp light is on.
3. Make sure that an object is not in the light
path.
4. Do sample dilution if necessary.
ERR04 Memory malfunction
1. Turn the instrument off and then back on.
2. Contact Technical Support if the error
occurs again.
ERR05 A/D is over the range
1. Make sure that the light shield is closed.
2. Contact Customer Service if necessary.
Table 3 Error codes (continued)
Error Description Solution
ERR06 A/D is under the range
1. Make sure that no object is in the light
path.
2. Contact Customer Service if necessary.
ERR07 Light leak
1. Make sure that the cover for the sample
cell compartment is closed.
2. Turn the instrument off and then back on.
ERR09 Printer time out error
1. Make sure that the external printer is
connected correctly.
2. Make sure that the external printer is
selected (online).
ERR10 System voltage out of
range
1. Turn the instrument off and then back on.
2. Contact Customer Service if the error
occurs again.
ERR11 System loop test error
1. Turn the instrument off and then back on.
2. Contact Customer Service if the error
occurs again.
Diagnostic codes
Table 4 lists the diagnostic codes that are used to get information about
instrument operation when instrument operation is in doubt.
To do a diagnostic test:
1. Push SETUP.
2. Use the arrow keys to enter a diagnostic code.
3. Push ENTER to show the diagnostic value.
4. Push UNITS/Exit to go back to Measurement mode.
