USING THE CAA 500MARKII THE CAA 500MARKII IS VERY EASY TO USE IN THE
DEFAULT SINGLE FREQUENCY MEASUREMENT MODE.  THE BAND SWITCH SELECTS THE
FREQUENCY RANGE OF INTEREST, AND THE FREQ CONTROL SETS THE MEASUREMENT
FREQUENCY WITHIN THIS RANGE.  SWR AND THE MAGNITUDE OF THE IMPEDANCE ARE
INDICATED ON THE CROSS NEEDLE METER, AND THE LCD PROVIDES ADDITIONAL
DIGITAL AND BAR GRAPH SWR AND IMPEDANCE INFORMATION.  BOTH THE AUTO AND
MANUAL SWEEP MODES DISPLAY SWR ONLY 6 1 MAXIMUM.  FOR THE AUTO SWEEP MODE,
THE BAND SWITCH AND FREQ CONTROL SELECT THE AMATEUR BAND OF INTEREST.  THEN
PRESSING SWEEP CENTER SWEEPS THE SELECTED FULL AMATEUR BAND.  FOR THE
MANUAL SWEEP MODE, PRESS GRAPH ON/OFF AND SET THE DESIRED CENTER FREQUENCY.
THEN PRESS THE SWEEP/ CENTER BUTTON, SET THE BAND SWEEP LIMITS, AND PRESS
A.P. OFF TO CONFIRM THE SETTINGS.  NOW MANUALLY SWEEP THE SWR OF THE
SELECTED BAND WITH THE FREQ CONTROL.  IN THE MANUAL SWEEP MODE, YOU CAN
CHANGE THE SWEEP COLORS AND OVERLAY UP TO FIVE MANUAL SWEEP RESULTS IN THE
DIFFERENT COLORS.  THIS PERMITS YOU TO SEE THE IMPACT OF CHANGES AS YOU
ADJUST YOUR ANTENNA SYSTEM.  MY PRIMARY ANTENNA IS A 43 FOOT VERTICAL WITH
A 160/80 METER BASE MATCHING NETWORK.  FIGURE 2 SHOWS THE 160 METER FIXED
FREQUENCY CROSS NEEDLE AND DIGITAL DISPLAY AT THE LOWEST SWR POINT.  FIGURE
