    1.2.2 Precautions for Transportation and Measurement (1) Precaution for transportation The internal electrode is not fixed to the shield box. Do not tilt the 12707, otherwise the internal electrode may fall. (2) Precaution for measurement If measurement is performed with the 12707 tilted, a sample will overflow or the internal electrode will not be fully soaked.
