Calibration

1. Open the cover plate & place 2-3 drops of distilled water onto the prism surface, close the cover plate, press lightly & ensure the water spreads evenly across the whole surface area without air bubbles or dry sections. (wait 30seconds until the water adjusts to ambient temperature)

2. Hold towards light source & look into the eyepiece, if the boundary line between the upper blue field & the lower white field is not located exactly on the 0°C waterline, adjust the correcting screw until both lines meet.

3. Wipe the water from the prism with clean dry cloth & replace the rubber correcting screw cover.

NOTE: under normal operating conditions the calibration only needs to be checked periodically

Maintenance

1. If the ambient temperature is not within the automatic temperature compensation range (10 – 30°C) the instrument must be calibrated before testing commences.

2. The prism must be cleaned thoroughly with a soft, clean damp cloth after each use – failure to do so will result in inaccurate readings & possible long term damage

3. The instrument must be kept in a dry clean environment to prevent condensation forming on the optical components

4. If used in accordance with the instructions & all warning are followed – the optical performance will remain constant & the instrument will give many years of reliable service.
