NOTE
When using a Chromatopac, select the sensitivity of this instrument such that the noise becomes several
percent of the plot range when the [ATTEN] setting of the Chromatopac is [0]. Next, select an [ATTEN] setting
that ensures that the targeted peak is within the plot range. If the peak height is beyond the plot range even
when [ATTEN] of the Chromatopac is set to the lowest sensitivity, change the sensitivity of this instrument to
low sensitivity.
The settings for sensitivity are shown below.
On shipping from the factory, the setting is [2] (MED).
