7. ATTENTION This equipment contains devices that can be damaged by electrostatic discharge ESD As solid state technology advances and as solid state devices get smaller and smaller they become more and more sensitive to 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 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 ATTENTION The preamplifier power supply at terminals V V and SC provides a nominal unregulated 10 and 10 volts for an external preamp If the 31022283 preamp is used it will perform correctly from this supply although its terminals are designated 16 16 and SC 110 9782 Series pH ORP Analyzer Controller Operator s Manual 3 00 Maintenance 10 2 Output Calibration Introducti

Operator s Manual 121 Maintenance 10 10 Determining and Entering a Solution Temperature Coefficient 10 10 1 Introduction Automatic temperature compensation Corrective adjustment or compensation is needed for the effects of temperature on pH measurement This is done automatically by the Analyzer Controller which offers two types of automatic temperature compensation They are referred to as conventional electrode temperature compensation Nernstian and solution temperature compensation Neither type of compensation applies to ORP measurement Conventional electrode temperature compensation Nernst Response Conventional temperature compensation is included in most pH instruments Compensation is made for the fact that the measuring electrode response is proportional to temperature as well as pH The electrode output is greater at higher temperature The Analyzer Controller uses information from a temperature sensor in the electrode assembly to adjust the measured value for this effect Conventional compensation is always active and requires no setup Note that the Durafet electrode preamplifier performs the basic temperature compensation Solution temperature compensation This type of compensation adjusts for the fact the actual pH of a solution will change if its temperature changes The change is so slight for normal applications it is usually ignored but for high purity water measurements it is significant By means of a sp
