Recommended Action
Verify the calibration setup and procedure. Make sure that no
water droplets are on the surface of the cap. Verify that the cap
lifetime has not expired yet.

unstable.
Salt may be present in the sample. Set the salinity factor in the
meter.
Verify that the temperature sensor (metallic pin along the sensor
shaft) is immersed in the solution.
