4.2 Troubleshooting
If any of the conditions described above have occurred, troubleshooting is required to determine the
repairs that are necessary.
4.2.1 Precautions
Because the Convectron gauge contains static-sensitive electronic parts, follow these precautions
while troubleshooting:
• Use a grounded, conductive work surface. Wear a high impedance ground strap for personal
protection.
• Do not operate the module with static sensitive devices or other components removed from the
product.
• Do not handle static sensitive devices more than absolutely necessary, and only when wearing
a ground strap.
• Rely on voltage measurements for troubleshooting module circuitry. Do not use an ohmmeter.
• Use a grounded, electrostatic discharge safe soldering iron.
Safety Precautions
Substitution or modifying parts can result in serious product
damage or personal injury due to electrical shock or fire.
Install only those replacement parts that are specified by MKS.
Do not install substitute parts or perform any unauthorized
modification to the module.
Do not use the module if unauthorized modifications have
been made
Safety Precautions
Failure to perform a safety check after the module has been
repaired can result in serious property damage or personal
injury due to electrical shock or fire.
If the module has been repaired, before putting it back into
operation, make sure qualified service personnel perform a
safety check.
