12707 Resistivity Chamber for Liquid Sample Operation Manual

1.2    Before Using the Product 

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. Consequently, normal measurement values cannot be 

obtained. 

Perform measurement on a flat horizontal workbench. 

1.2.3
