Conductivity/Resistivity Analyzer/Controller

ATTENTION

Most of the operations described in this section are performed with the unit off-line (that is, not connected to the process). However, some of the operations described in this section are performed with the Analyzer/Controller on-line. Your process may be affected as soon as you initiate the maintenance function.

ATTENTION

This equipment contains devices that can be damaged by electrostatic discharge (ESD). The damage incurred may not cause the device to fail completely, but may cause early failure. Therefore, it is imperative that assemblies containing static sensitive devices be carried in non- conductive plastic bags. When adjusting or performing any work on such assemblies, grounded work stations and wrist straps must be used. If soldering irons are used, they must also be grounded.

A grounded work station is any conductive or metallic surface connected to an earth ground, such as a water pipe, with a 1/2 to 1 megohm resistor in series with the ground connection. The purpose of the resistor is to current limit an electrostatic discharge and to prevent any shock hazard to the operator. The steps indicated above must be followed to prevent damage and/or degradation, which may be induced by ESD, to static sensitive devices.
