Wattmeter Scale:
The Power LED bargraph displays either 0 to 100 watts or 0 to 1000 watts
full scale. To toggle between these two scales, press
Func -> L Up
. The LED marked “100” or
“1000” will light momentarily to indicate the newly selected scale.
Automatic Tuning Mode:
The AT-1000ProII may be set for either semi-automatic tuning or
fully automatic tuning. In semi-automatic tuning mode, a tuning cycle will not begin unless
specifically requested by pressing the
Tune
button. In fully automatic tuning mode, a tuning
cycle will begin any time there is RF present and the SWR exceeds a pre-set level. The default
setting is fully automatic tuning mode.
To toggle between semi- and fully automatic modes, press
Func -> C Dn
. The LED display
will show one of the two patterns to indicate which mode has been selected:
Automatic Tune SWR Threshold:
When the AT-1000ProII is in fully automatic tuning
mode, an automatic tuning cycle will begin any time RF is present and the SWR has exceeded a
set threshold. This threshold is user-programmable to any value between 1.7:1 and 3.0:1. To set
the automatic tune SWR threshold, press
Func -> L Dn
repeatedly (press
Func,
then
L Dn;
Func,
then
L Dn,
and so on...) to cycle through all the options. The SWR threshold will be
displayed on the SWR scale momentarily.
