Metrohm 838 Advanced Sample Processor, Introduction

1 Introduction
Like all Metrohm Sample Processors, the 838 Advanced Sample Proc-
essor can be operated as stand-alone device or be controlled entirely
by a PC software (e. g. «IC Net»). In the latter case the particular func-
tions of the instrument are invoked directly by the PC software. The
keypad of the 838 Advanced Sample Processor therefore is not neces-
sary.
In a stand-alone system with a keypad connected, the 838 Advanced
Sample Processor can execute methods containing command se-
quences automatically. These sequences may be programmed freely in
a wide range. The Sample Processor can even be operated manually to
prepare a sample series.
«IC Net 2.3» (Service release 3 or later) sets a parameter in the 838
Advanced Sample Processor, which forces the Sample Processor to
reset all of it's device settings and delete all stored methods on start-
up (RAM init). This behavior is intended and necessary for controlling
the Sample processor with «IC Net».
If a 838 Advanced Sample Processor is to be used as a stand-alone
system with keypad control and instrument methods, which previously
was controlled by «IC Net 2.3», the setting mentioned above has to be
switched off beforehand. In «IC Net» uncheck the check box "Autoinit"
which is accessible after right-clicking the Sample Processor icon in
the working system.
The 838 Advanced Sample Processor is delivered with four standard
methods for voltammetric analysis. These can be used in the connec-
tion with the Metrohm 797 VA Computrace.
Operating and programming of the 838 Advanced Sample Processor is
described in this Instructions for Use.
