INFORMATION NOTE
The PGA-710 Autoanalysis System is a precision instrument. Depending on the
environment and while rare, the System’s zero reference may be affected by high
levels of extraneous transmitted energy, or “noise” i.e., EMI/RFI. All units are easily
zeroed as described above unless influenced by excessive noise. The noise level
will be recorded and displayed by the system unless it is eliminated, or the system is
shielded from the transmitted energy in some manner.
