The TO2 analyzer gives erratic and very insensitive readings.
Check to see that the electrolyte level is within the limits indicated on the reservoir. Add
distilled water as required. If the level is within limits, the electrolyte may have been
contaminated. Refer to section 4.2 above for proper procedure to replace electrolyte. If
replacement of electrolyte does not improve the performance of the sensor, the sensor may
have been damaged due to over-pressurization or poisoning. Sensor replacement may be
required as described in section 4.3 above.
