Recorder calibration Zero, Full Scale,
Normal
Use this setting to calibrate a
recording device. Select Zero to set
the output signal to zero volts. Select
Full Scale to set the output signal to
the selected full-scale voltage (0.01,
0.10, or 1.00 V). For normal
operation, select Normal (the
default) to output a signal
corresponding to the detector output.
Offset level 0 to 100% Use this setting to adjust the zero
position of the analog output when it
is plotted. The value entered is a
percentage of the full-scale analog
output. An offset allows a recording
device to plot the signal if it becomes
negative. The offset level does not
affect the magnitude of the output
signal.
Polarity Positive, Negative Use this setting to set the polarity of
the analog output signal to either
positive (the default) or negative. In
applications in which the analyte
output is lower than the background
signal, the polarity must be negative
to display peaks instead of dips on the
chromatogram.
Mark 10% of the full-scale
analog output
Use this setting to send a positive
pulse to the analog output as an event
marker. A mark is typically used to
indicate a sample injection.
