Final Check
Pressing the FUNCTION key rotates the LCD display through the following
screens:
1. After pressing the FUNCTION key on the front of the unit, the Forward
and Reverse power readings will appear on the LCD display (see Figure
3-4a).
Figure 3-4a.
Press the FUNCTION key to read Powers
2. Pressing the FUNCTION key again will display Voltage and Current on
the LCD display (see Figure 3-4b).
Figure 3-4b.
Press the FUNCTION key to read Voltage and Current
Note: At each screen, pressing the LOWER or RAISE key changes the output power
only. PA VOLTS and PA AMPS is another way of indicating the power output,
accomplished by multiplying the voltage by the amperage (current), then multiplying
the result by the efficiency.
Readings should be recorded weekly to keep track of changes, which may indicate
developing problems such as antenna or coax deterioration.
