o
Check that the positive wire lead (yellow connector) is securely
attached to the top of the conductivity rod. Check for corrosion inside
of the yellow connector and on top of the conductivity rod. Clean if
needed.
o
If the yellow connector is securely attached, use a multimeter to see if
3.3 Vdc is present.
o
If 3.3 Vdc is not present, check for a broken wire and recheck the
yellow connector to ensure that it is not loose or broken.
Symptom #3: Sampler clock drifts outside of specification:
•
Connect to the computer and sync the clock by using the
Clock
