    5. With the unit on, press the ZERO button. A refractive index reading between 1.3329~1.3331 indicates that the unit accurately reads to the calibrated zero point. If the unit is out of range, a flashing crosshair symbol will be displayed, indicating that recalibration is required. Press any other button to exit this function. Perform Zero Checking if the unit has sustained a shock, is subjected to temperature changes, or seems inaccurate. PARAMETER SETTINGS A.

C. When diluting samples, be sure to use a pure solution such as distilled water. D. Sample contains suspended solids. Filter and thoroughly mix the sample before testing. E. Perform a calibration and check the zero point. F. Replace the battery. G. Outside light can cause erratic readings, make sure to close the COVER to the PRISM during measurement. 7. BATTERY REPLACEMENT A. When the battery is low, the above symbol appears on the LCD. B. Open the back cover to replace the 9V battery. C.
