OVERVIEW

While the Hazardous Area Oxymitter 5000 electronics provides a significant 
number of diagnostic alarms to assist in troubleshooting potential problems, it 
is good to place these alarms in perspective with respect to the instrument's 
operating principles:

When the Zirconium Oxide sensing cell is heated to its setpoint [736°C 
(1357°F)], the cell will generate a voltage that re presents the difference 
between the process O

2

% and the reference O

2

% inside the probe (20.95% 

O

2

 ambient air).

Test points, Figure 8-1, are provided to read the raw millivolt value generated 
by the thermocouple that controls both the cell temperature and the raw cell 
signal.

The cell temperature at test points 3 and 4 should always be stable at 
approximately 29 to 30 millivolts, which represents the 736°C setpoint 
temperature.

When flowing calibration gasses, the raw cell millivolt value at test points 1 
and 2 should represent the levels on the chart in Figure 8-1. Note that the raw 
cell millivolt value increases logarithmically as the O

2

 concentration 

decreases.
