Major Internal Components

The major components in the Control Unit are shown in Figure 5-3.

Figure 5-3: Control Unit Major Internal Components

WARNING: HAZARDOUS VOLTAGES EXIST ON CERTAIN

COMPONENTS INTERNALLY WHICH MAY PERSIST
FOR A TIME EVEN AFTER THE POWER IS TURNED
OFF AND DISCONNECTED.

The 3010TA Control Units contain the following major components:

•

Power Supply

•

Motherboard (with Microprocessor, RS-232 chip, and
Preamplifier PCB)

•

Front Panel Display Board and Displays—

5 digit LED meter
2 line, 20 character, alphanumeric, VFD display

See the drawings in the Drawings section in back of this manual

for details.

The Front Panel Display Board is accessed by unlatching and swinging

open the front panel, as described earlier. Other electronic components are
accessed by removing four rear panel screws and sliding out the entire
chassis. See Figure 5-4, below.
