Manual Tune Sub-Menu; Measure Sub-Menu - Acom 2000R Operating Manual

4-2. MANUAL TUNE sub-menu

During manual tune do not apply continuous drive longer than 3 minutes and after
that leave pauses of 1-2 minutes for cooling of the tubes.
If for some reason you prefer to match the antenna impedance manually, you can do it in the MAN.TUNE
sub-menu. The procedure starts as for AUTO TUNE, but you will need to adjust the LOAD and TUNE
settings yourself:
Below the inscriptions TUNE and LOAD are indicated the numbers of the current positions of the
motors which control the respective capacitors. To the left of them there are arrows indicating which
way the automatic procedure would move the motor (they are correct only at drive power of 5 to
50W). When changing the direction of the arrows you will hear a sound signal.
The current output power is shown below Pout on the display.
By means of the
selected in brackets. With the
select STO (store), in order to memorize the tuning done as USR in the nonvolatile memory.
To leave the procedure, remove power and press
If you adhere to the tune-up criteria following the arrow prompts, you will achieve
the same results as AUTO TUNE. Because of this, the MAN.TUNE procedure is
only appropriate if you have tune-up criteria of your own. We recommend you use
the AUTO TUNE procedure instead.
