שפּראַך
וואָרענען
- Cold or hot measuring solution
לייזונג: Drop in the measuring solution and wait 20 seconds before measuring. Because the instrument needs to do temperature supplement, this requires the instrument and the measuring solution to maintain the same temperature ,and this takes more than 20 seconds.
- Measuring solution containing suspended substances
Solution (Step 1):
Remove suspended solids from measuring solution with filter spoon or gauze as much as possible.
Solution (Step 2):
Mix measuring solution evenly (do not use metal and hard objects, and avoid scratching the optical prism). Because uneven measuring solutions or suspended solids can lead to instrumental uncertainty in measurement.
רייניקונג
If there is dirt in the measuring slot or the instrument is not used for a long time, It should be cleaned first.
נול באַשטעטיקן
Measure whether the clean water or pure water is 0.0% before using, and if it is not 0.0%, it will be zerged first.
