Troubleshooting
and Maintenance
Routine maintenance, including periodic inspection of essential analyzer parts,
will help ensure continuing high performance.
Routine Maintenance Checklist
1. Calibrate the analyzer at least once each week during the first four
weeks and then once every two weeks during the next eight weeks.
Afterwards, the analyzer should be calibrated once a month.
2. Check the electrolyte level.
3. Check the pressure of the air supply to the analyzer. Air pressure
should be maintained between 70 and 80 psig.
Ultra Trace Sensor Maintenance
CAUTION: Protective equipment including but not limited to gloves,
safety glasses, face shield and rubber apron must be worn
while handling electrolyte. The safety of the people in the
vicinity of the area in which the electrolyte is being
handled must be given similar consideration. Please refer
to Material Safety Data Sheets to learn about potential
hazards and corrective action in case of accident.
Adding Distilled Water to the Electrolyte
Ultra Trace sensor electrolyte levels above the red marker have no effect on
Ultra Trace sensor performance. However, once the level falls below the red
marker, the Ultra Trace sensor may deliver false output signals. The Ultra Trace
sensor holds approximately 250 ml of electrolyte when filled to the green upper-
level marker. During use, however, water will evaporate and cause the
electrolyte level to drop.
The electrolyte level detector mounted inside the Ultra Trace sensor continu-
ously monitors the electrolyte level and triggers automatic addition of water to
the sensor. The rate of addition is set close to the rate of evaporation of water
