MEASUREMENT

7.1 Conductivity Measurement

1. 

Immerse the electrode into the sample solution.  Stir
moderately.

Make sure that the meter is in  the  Measure  mode.  If  you  are
using the 2-cell electrode, and separate temperature probe is
NOT available then meter takes 25¡C as default temperature.

2. 

When the meter senses that the reading has stabilized, the
stable icon will appear under the reading. The  reading  may
be recorded at this time.

STABLE icon will only appear provided that it  has  been  set  to
ÔOnÕ mode in setup. See Program 16:  Enable  the  Stable  icon,
page 22.
