Thermo Fisher Scientific Model 5030i SHARP Instruction Manual 7-3
Read the safety precautions before beginning any procedures in this
chapter.
WARNING The service procedures in this manual are restricted to qualified
service representatives. ▲
If the equipment is operated in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired. ▲
The detector assembly should be replaced by a qualified technician
knowledgeable in dealing with radiation precautions. By removing the
detector assembly, the C-14 radioactive source is partially exposed. Safety
glassed must be worn during this replacement procedure. The amount of
C-14 meets the U.S. NRC regulations as an exempt amount of radioactive
source <100 μCi. ▲
The detector pre-amp assembly has a power backup built in. “DO NOT
OPEN” caution handeling. Backup power will dissipate after 8 hours. ▲
CAUTION The detector window is very fragile. Handle with great care and
do not wipe or touch the window. Furthermore, do not touch the solder
cable connection (electrode) with your bare fingers. The oils from your skin
can damage the detector. ▲
Safety glasses must be worn while replacing the detector assembly.
▲
If the LCD panel breaks, do not let the liquid crystal contact your skin or
clothes. If the liquid crystal contacts your skin or clothes, wash it off
immediately using soap and water. ▲
Equipment Damage Some internal components can be damaged by small
amounts of static electricity. A properly grounded antistatic wrist strap
must be worn while handling any internal component (Figure 7–1). If an
antistatic wrist strap is not available, be sure to touch the instrument chassis
before touching any internal components. When the instrument is
unplugged, the chassis is not at earth ground.
▲
Do not remove the LCD panel or frame from the LCD module.
