7. ERROR MESSAGES
On Zero Reading
On Sample Reading
The meter has lost its configuration. Contact your dealer or the
nearest Milwaukee Instruments Customer Service Center.
"Light high": there is too much light to perform a measurement.
Please check the preparation of the zero cuvet.
"Light low": there is not enough light to perform a measurement.
Please dilute the sample five times (see GENERAL TIPS FOR AN
ACCURATE MEASUREMENT).
"No Light": the instrument cannot adjust the light level. Please
check that the sample does not contain any debris.
"Inverted": the sample and the zero cuvet are inverted.
The sample absorbs less light than the zero reference. Check
the procedure and make sure you use the same cuvet for
reference (zero) and measurement.
A flashing value of the maximum concentration indicates
an over range condition. The concentration of the sample
is beyond the programmed range: dilute the sample and
measure again.
