Measurements with Manual Temperature Compensation
Use the manual temperature compensation feature if you
do not have a temperature sensor (the cell included with
your meter has a built-in temperature sensor). This feature
lets you manually set the meter to any temperature
between –9.9°C and 110°C. The conductivity meter will
compensate readings for the temperature you set.
1. Make sure you are in MEAS mode and that there is no
temperature sensor plugged in to the meter. Press the
MODE key and select temperature mode (TEMP).
The ATC indicator will not appear.
See Figure 16.
2. Press the CAL/MEAS key to enter calibration mode.
The primary display shows the measured Conductivity
value, and the secondary display shows the tempera-
ture at factory calibration value. The CAL indicator will
flash.
3. Press the
▲
or
▼
keys to manually adjust the tem-
perature reading . You can select any temperature
between –9.9°C and 110°C.
See Figure 17.
4. Press the ENTER/RANGE key to confirm your
selected temperature. The meter will automatically
revert to measurement mode. The meter is now pre-
pared for manual temperature compensation.
5. Press the MODE key to switch to conductivity read-
ings. The MEAS annunciator together with the auto-
ranging annunciator (AUTO) displays on the top center
of the LCD.
See Figure 18.
6. Rinse the probe with deionized or distilled water
before use
to remove any impurities adhering to the
probe body. Shake or air dry.
7. Dip the probe 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.
8. Stir the probe gently in the sample to create a
homogenous sample.
9. 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. To turn off or on READY
Indicator, see the “Ready Indicator” section on page 13.
