 | Always wipe the prism surface and daylight plate dry between and after each measurement. |
| Do not allow saltwater to remain anywhere on the unit. When through, wipe clean with damp cloth (fresh water) then wipe dry. |
| Keep in dry place and preferably in the ambient temperature in which you are taking samples. (this will eliminate constant re-calibration). |
| DO NOT immerse unit past the daylight plate when taking samples direct from liquid source. |
| Submersion past the daylight plate partially or completely will cause leaking and/or condensation
inside the unit, distorting the view and ultimately damaging the bi-metal compensating device. (internal water damage is not covered by warranty).
