Why does LaMotte TC-3000 Measuring Instruments give erroneous readings?
Erroneous readings from the LaMotte Measuring Instruments can occur if a measurement was taken with the lid open. Ensure the lid is closed, and then read again.
What to do if LaMotte Measuring Instruments shows '>' on display?
If your LaMotte Measuring Instruments displays '>', it indicates an over range situation. This means the sample you are testing is outside of the acceptable measurement range. To resolve this, dilute the sample and test it again.
Why does LaMotte TC-3000 Measuring Instruments freeze?
The LaMotte Measuring Instruments may freeze if the lid was opened while a reading was being taken. To fix this: 1. Close the lid. 2. Read again. 3. Unplug the adapter. 4. Plug the adapter back in to reset the device.
