ELECTROSTATIC DISCHARGE
CAUTION
The electronic parts of the Analyzer Module can be irreparably damaged if exposed to electrostatic discharge (ESD).
The instrument is ESD protected when the covers have been secured and safety precautions observed. When the housing is open, the internal components are not ESD protected anymore.
Although the electronic parts are reasonable safe to handle, you should be aware of the following consid- erations:
Best ESD example is when you walked across a carpet and then touched an electrical grounded metal doorknob. The tiny spark which has jumped is the result of electrostatic discharge (ESD).
You prevent ESD by doing the following:
Remove the charge from your body before opening the housing and maintain during work with opened housing, that no electrostatic charge can be built up.
Ideally you are opening the housing and working at an ESD - protecting workstation. Here you can wear a wrist trap.
However, if you do not have such a workstation, be sure to do the following procedure exactly:
Discharge the electric charge from your body. Do this by touching a device that is grounded electrically (any device that has a three - prong plug is grounded electrically when it is plugged into a power recep- tacle).
This should be done several times during the operation with opened housing (especially after leaving the service site because the movement on a low conducting floors or in the air might cause additional ESDs).
