5.3 Cell Replacement

The Micro-Fuel Cell is a sealed electrochemical transducer with no

electrolyte to change or electrodes to clean. When the cell reaches the end of

its useful life, it is replaced. The spent fuel cell should be discarded in accor-

dance with to all applicable safety and environmental regulations. This

section describes fuel cell care as well as when and how to replace it.

The Class L-2C Micro-Fuel Cell is used in the standard Model 3020T.

If any other cell is supplied with your instrument, check the front of this

manual for any addenda applying to your special model.
