2.2.1 Range Knob
The Range knob is shown in Figure 4. This knob adjusts the signal gain of the
Model 1815-C. The units arrayed around the knob reflect the units of measure-
ment when using a particular type of Newport detector. As an example, if a
measurement with a Low-Power detector with its attenuator was being made,
then the proper units would be read from the middle (blue) column of units
found on either side of the knob.
