6. Dip the rinsed probe into the second container.
Tap probe on the bottom of container to remove
air bubbles. Wait about 15 mins to make the probe
stabilize to the solution temperature.
7. Press "CAL" more than 2 seconds to begin
calibration. The conductivity value of solution will
blink on LCD.
8. Press "p" and "q" to change the value in
order to match the value to the standard
solution(solution must be referred to
normalization temp. 20oC if P1.2 is adjusted as
20 oC). You can adjust the conductivity reading
for +30%. However, if the measured value and
standard value differs by more than 30%, it is
suggested to clean probe or replace meter.
9. When the "CAL" stop flashing, you can
press"SET" less than 1 second to confirm and
return to conductivity measurement mode. If
"CAL" always blinks, check if the calibration
solution is stable enough and if the step 8 input
value is correct or not.
10. Repeat 1~9 for other ranges if needed.
11. To exit conductivity calibration mode without
confirming, press "SET" in step 9 more than 2
seconds.
