      If your Nalco Measuring Instruments give you erroneous readings, first, re-analyze the sample to verify the suspected result. Then, analyze a fresh sample taken from the same sample point; if the new sample reads differently than the first, run the sample again to verify the result. Also, recalibrate the instrument and retest the samples. Finally, check the pump/product to ensure the product is being delivered to the system.

      Error codes on Nalco Measuring Instruments can result from several causes. The screen might show a low battery and no number. It could also be due to an incorrect calibration solution, or dirty or broken optics. Another cause is when the reference channel returns exactly zero, a divide by zero has occurred in an earlier step, or the calibration has been deleted. Finally, it can be caused by an incorrect zero solution, or dirty or broken optics.
