5.3.2.4 Measurement unit
Measuring interface has two units of selecting methods, one is default instrument unit "MS/m
and % IACS" (see 5.3.4.7 unit selection), which used in data storage, calibration, measurement
mode. Another is quick convert method, in the measurement of interface, press "

press key once will converse the unit once, such as "MS/m

then open or from other interface returns to measurement interface, measurement unit recovery to
the original default units.

temperature sensor (automatic temperature compensation for temperature sensor, see
5.3.4.3) , the temperature sensing end is close to the surface of the specimen until
temperature stable, press "

the "OK" button, σ(Tc)values in brackets immediately modified into TA temperature value
and stored until the next change. Conductivity value
