5.3 Fuse Replacement

There is no replaceable fuse. Rather, this unit has an internal solid-
state fuse with overcurrent protection where it increases resistance with
higher temperatures caused by increased current flow, and automatically
resets when temperature cools to a safe level.
However, if it persists in preventing the unit from powering on,
contact tech support at Teledyne Analytical Instruments for service.

5.4 System Self Diagnostic Test

Refer to Section 4.5.3 to initiate a Self-Diagnostic Test.
Table 5-1: Self-Test Failure Codes

5.5 Major Internal Components

The Micro-Fuel cell is accessed by pressing the top latch button
and swinging the front panel down. Other internal components are
accessed by removing the four rear panel screws and sliding out the
entire chassis. See Figure 5-4, below. The gas piping is illustrated in
Figure 2-5, and the major electronic component's locations are shown in
Figure 2-7, in chapter 2.
