Analog output settings—zero, range, and attenuation

Figure 23 Range settings
There are limits to usable range settings for some detectors. The table below
lists the valid range setpoints by detector.
Range may be run time programmed. See chapter 7 for details.
Attenuation—for analog outputs only
Attenuation(Attn) scales the presentation of output on 0- to 1-mV strip chart
recorders. Valid setpoints are from 0 to 10 and represent 2
0
to 2
10
. As with range,
each higher setpoint value reduces the size of the chromatogram by one half,
while each higher setpoint doubles the size.
Attenuation is in addition to range. Thus, the total scaling factor is:
