5. Conductivity Measurement
You can measure readings using Automatic Temperature
Compensation with a temperature sensor, or using
Manual Temperature Compensation without a tempera-
ture sensor. The probe included with your meter features
a built-in temperature sensor.
Measurements with Automatic Temperature Compensation
1.
Switch on the meter, if necessary.
The MEAS annun-
ciator together with the auto-ranging annunciator
(AUTO) displays on the top center of the LCD.
See Figure 13.
Make sure the temperature sensor is
plugged in the back of the meter.
2.
Rinse the cell with deionized or distilled water
before use
to remove any impurities adhering to the
probe body. Shake or air dry.
3.
Dip the cell and temperature sensor into the
sample.
NOTE:
When dipping the probe into the sample, make
sure the tip of the probe is completely immersed
into the sample above the air holes about
3
⁄
4
" from
the bottom of the probe.
Also make sure there are
no air bubbles trapped in the slot of the probe, or
your measurement will be incorrect. To remove air
bubbles, tap the probe gently while the probe tip is
submerged.
4.
Stir the probe gently in the sample
to create a
homogenous sample.
5.
Take readings.
Allow some time for the temperature
reading to reach the solution temperature. If the Ready
mode is switched on, the READY indicator will light
when the reading is stable.
See Figure 14.
See page 13
for information on the READY indicator.
