The measured value is blinking
The measured conductivity value exceeds the
measurement parameters (when conductivity value is
displayed).
Display range: 0.00 – 19.99 (when cell constant is 100
m
-1
)
Check this point
As shown in the diagram, use a jumper wire or bent
paper clip to short the meter by touching both the center
pin and some metal part in the electrode connector.
If the flaching measured value disappears when this
done, the meter is nomal.

How to solve problem
The sample
solution is
inappropriate.
Change to a sample solution with
