During calibration of a Clark polarographic O2 analyzer, you cannot get the sensor to read 100% when exposed to 100% O2, even after adjusting its calibration control. The unit has new batteries
Which of the following actions would be correct?
a. Use it only with low FiO2 values.
b. Send the device out for repair.
c. Replace the unit's batteries.
d. Change the sensor or electrode.
ANS: D
If the analyzer still does not calibrate on fresh batteries, the problem is probably a depleted sen-sor. With most analyzers, a depleted sensor must be replaced (some Clark electrodes can be re-charged).
