9.2.4 IN CNF (Input Configuration)
Input configuration is used to select:
• 50 or 60 Hz line frequency [INP.1]
• slow or fast read rate [INP.2]
• unipolar or bipolar inputs
• cold junction compensation [INP.5]
INP.1 and INP.2 are related to each other. If your power requirements require
50 Hz, you can have optimum integration in FAST read mode (12/sec). In the
FAST mode, you need a jumper in the S1A position on the vertical Signal
Input Board. If you set the SLOW read rate, this jumper should be removed
to avoid overloading the integrator. SLOW read rate produces less noise.
