possible leakage caused by damage in shipment.
1.If not already removed from the analyzer, remove the top cover of the analyzer module and locate and remove the five mounting screws which hold the Sensor Assembly (Sensor, flowmeter, plumbing) to the module. Care should be taken not to lose the screws as they have metric threads.
2.Carefully lift out the Sensor Assem- bly. Place on a flat surface and re- move the black Sensor cover by unscrewing clockwise.
3.Refill the the Sensor per Section 4- 2a, steps 2 through 5.
4.Allow the Sensor to stand for ap- proximately 15 minutes, then check for leaks around the base of the reservoir, at seams and corners.
5.If a leak is found, drain the Sensor. Contact the factory before proceed- ing.
6.If no leaks are detected drain the Sensor, refill with one bottle of elec- trolyte. Use the entire contents of the bottle.
NOTE
Do not add water. The volumn and concentration of the bottled electrolyte is
4-3 LINEARIZATION
After installation of a new Sensor, it will be necessary to load the new calibration data supplied with the Sensor.
NOTE
It is not necessary to load lineariza- tion data on a new analyzer which has been filled with electrolyte. The data is
The data supplied with the new Sensor and must be entered exactly as shown the the Se- nosr data sheet.
