extremely short in AUTO T.C.

Mode.

T.C. element open.

Check T.C. element as instructed in Section 6.5

and replace sensor if defective.

Sluggish or slow meter

indication for real changes in

pH level.

Electrode coated.

Clean sensor as instructed in Sections 6.3 or

6.4. Replace sensor if cracked.

Electrode at end of life.

Replace sensor.

Transmitter cannot be

standardized.

Electrode coated or cracked.

Clean sensor as instructed in Sections 6.3 or

6.4. Replace sensor if cracked.

Transmitter short spans

between two different buffer

values.

Electrode at end of life, due to old glass or high

temperature exposure.
