Chapter 7. Maintenance
7.1.1 Checking the Electrolyte Level
Using the level indicator window on the oxygen cell, check the electrolyte level. The electrolyte should cover
about 60% of the window. The electrolyte level should be between the Min and Max lines, as shown in
Figure 75 below.
When the Delta F Oxygen Cell connections are made to the moisture.IQ, the analyzer can detect the electrolyte
level and indicate when it is low. When the electrolyte level is low, all oxygen readings are highlighted in amber
and an "Oxygen Fluid Low" error message is displayed beneath the measurements.
7.1.2 Replenishing the Electrolyte
Once the oxygen cell receives the initial charge of electrolyte, you should monitor the level regularly. DO NOT
let the fluid level drop below the MIN level mark on the window.
WARNING! The electrolyte contains a strong caustic component and can be harmful if it comes in
contact with the skin or the eyes. Follow proper procedures for handling the caustic (potassium
hydroxide) solution. Consult your company safety personnel.
To raise the fluid level in the reservoir, add DISTILLED WATER slowly in small amounts. Check the level as you
add the distilled water, making sure you do not overfill the reservoir. The electrolyte mixture should cover
approximately 60% of the level indicator window.
