Signal Output

For analytical information from a detector, proper settings for
RANGE 2 ()
and
ATTN 2 ()
are determined such that peaks of interest are on scale
at the integrator or chart recorder: peaks of interest must neither flat
top by exceeding the allowed maximum output level, nor be too small to
be measured. Table 5•3lists maximum detector output producing +1 volt
at the +1V output for each
RANGE 2 ()
setpoint value.
