The series of C1950 instruction manuals is shown in Fig. 1.1.
The
Standard Manuals
, including the specification sheet, are
supplied with all instruments. The
Supplementary Manuals
supplied depend on the specification of the instrument.
This installation supplement for the C1950 series Recorders
contains information and procedures to be implemented at
installation to avoid potential problems caused by electrical
noise, particularly Electro Magnetic Interference (EMI), or
Radio Frequency Interference (RFI). The best method of
controlling and limiting the effects of EMI and RFI is a
comprehensive program including all of the recommendations
contained in this supplement such as shielding, grounding and
radio transmission exclusion zones.
Each of these practices should be considered routine in
assuring and safeguarding public health and safety, and in
maintaining the integrity of electrical instrumentation.
