P2.3: Temperature Normalization 20 or 25°C
The conductivity of solution varies greatly with
temperature. The meter’s automatic temperature
compensation (ATC) feature adjusts conductivity
measurements to factor out fluctuations in the readings
caused by temperature.
The meter readings are referenced to or normalized at a
standard temperature: either 20° or 25°C. This feature
lets you compare conductivity readings from various
temperatures. Under the default condition, the meter
normalizes all readings to 25°C.
1.

keys
to toggle the tempera-
ture normalization setting to 20 or 25°C.
See Figure 28.

Press the ENTER key
when you have made your
selection. The meter automatically scrolls to Setup
parameter 2.4. To exit the SETUP mode, press
CAL/MEAS.
P2.4: Cell Constant Selection
Select the nominal cell constant depending on the
probe you use. The standard probe included with the
meter has a nominal cell constant of 1.0. With this
program, you can use an probe with K=0.1, for low
conductivity measurements below 20 µS, or an probe
with K=10.0, for high conductivity measurements above
20 mS.
1.
Press the MI/

or MR/
▼
keys
to toggle between a
cell constant of 1.0, 10.0, and 0.1.
See Figure 29.

Press the ENTER key
when you have made your
selection. The meter automatically returns to
Measurement mode.
