Please check that the sample does not contain any debris. Quantity/test 4 mL "Light Low": there is not enough light to perform a measurement. Please check the preparation of the Glycerol cuvet. "Light High": there is too much light to perform a measurement. Please check the preparation of the Glycerol cuvet. b) on sample reading There is too much light for the sample measurement. Please check if the right sample cuvet is inserted. "Cal": calibration was not performed. Follow the instruction in the operational guide for calibrating the meter. A blinking "100. 0" on sample reading is a warning that the Glycerol Reference cuvet is still inserted in the instrument, or indicates that the sample absorbs less light than the Glycerol Reference. Check the procedure and recalibrate the instrument. · Do not use the same cuvet with glycerol for more than 5-10 times to perform calibration and dispose of it after 1 day has passed. · Never re-use maple syrup sample cuvets, dispose of them after use. · Use one syringe for glycerol, and the other one for syrup in order to avoid contamination. Note: Maple Syrup samples exposed to direct sunlight and/or air will darken over time. This is caused by microorganisms. · Remove the Glycerol cuvet. · Use the second syringe to add to a clean cuvet 4 mL of maple syrup, up to 5 mm (0. 2") below the rim.
