Adding Water to the Reservoir

If the analyzer is to be used continuously for on-line gas analysis, then add

approximately 800 cc of distilled water to the reservoir. The rate of water

addition to the sensor is controlled by the metering valve MV3 located adjacent

to the reservoir, below the top cover plate. The valve MV3 is also accessible

from the rear of the analyzer.

The water drip rate is set at the factory at 1 drop every 2–4 minutes. This drip

rate is close to the rate of evaporation of water from the Ultra Trace sensor.

However, if the water drip rate is not proper, the electrolyte level in the Ultra

Trace sensor will not be maintained at the desired level (between the yellow and

green level markers). A drip rate that is too slow will cause the electrolyte level

to drop slowly. If this occurs, open MV3 slightly (

control knob anticlockwise. See Figure 3-11 for the location of MV3. Repeat

this step if necessary.

CAUTION:

If you open valve MV3 too wide, an excessive amount of water

will enter the sensor and the output will increase but will

slowly return to the original value. With MV3 open too wide,

the level detector will open and close more frequently causing

output instability. If this occurs, close MV3 slowly until the

drip rate is normal. If you experience difficulty in adjusting

MV3, you may add prepurged water directly to the sensor

through the filler port.
