Insert the probe into demineralized
water or distilled water for about 30
minutes to rinse the probe.
Select the conductivity standard for
calibration. ( See page 8)
Pour 4 cm (deep) of the solution into
two separate clean containers(A&B).
Turn on the meter, the entire display
flashes three times and then returns
to the normal measurement mode.
5.Rinse the probe in one of the
containers. Gently stir the probe.
6.Dip the rinsed probe into the other
container. Tap the probe on the bottom
of container to remove air bubbles.
Let the probe stabilize to the solution
temperature.
Fo llow the below steps
for
conductivity calibration:
4cm
K=0.966
B( Step 6)
4cm
K=0.9 66
A(Step 5)
7.Press CAL key more than2 seconds to
enter calibration mode. The probe
auomatically detects the conductivity
value of solution and blinks the value
on the LCD (Fig. H)
