HFV 8000 Generator
1. Verify that the generator is set to the desired frequency band for your application
(see “Setting the Frequency Band” on page 5-11 ).
2. Press the Display Mode button on the front panel repeatedly until the display
reads:
Top line—Press and Hold
Bottom line—Center/Auto Tune
3. Press and hold the Display Mode button for at least five seconds until the Load
Regulation indicator flashes.
Note: The load regulation indicator will begin to flash, indicating center
frequency mode. (See also
“Display Mode and the LCD Display
Indicator” on page 5-16 .)
To verify the operating frequency while in center frequency mode, select MODE 1 on
the front panel LCD display (see also “Display Mode and the LCD Display Indicator”
on page 5-16 ).
Note: Cycling AC power (circuit breaker) to the generator will cause the generator to
automatically return to automatic tuning mode. You will need to repeat the steps
in
“Selecting Center Frequency Mode” on page 5-12 to return to center
frequency mode after cycling the power.
Automatic Tuning Mode
Automatic tuning, mode continually adjusts the frequency to minimize the mismatch
to the generator. This mode is particularly useful when you expect large variations in
operating impedance.
SELECTING AUTOMATIC TUNING MODE
To select automatic tuning mode:
1. Press the Display Mode button on the front panel repeatedly until the display
reads:
Top line—Press and Hold
Bottom line—Center/Auto Tune
2. Press and hold the Display Mode button for at least five seconds until the Load
Regulation indicator does not flash.
Note: When the Load Regulation indicator is not flashing, the generator is in
automatic tuning mode. (See also
“Display Mode and the LCD Display
Indicator” on page 5-16 .)
