5 – OPERATION
Operating SMΩRF is easy and intuitive, but to use it effectively and to maximal pleasure, it is important to
understand its structure and relationship between data and settings.
SENSOR SELECTION
First basic selection on SMΩRF is a
SENSOR focus. If you have only one
SENSOR, it is just the matter of pressing
bottom
SENSOR 1 button [12]. Press
bottom SENSOR 1 button briefly to
change focus to that sensor. When
SENSOR 1 is selected, red SENSOR 1
indicator [7] is steadily lit.
If SMΩRF has both sensors installed,
there are more options. For manual
selection of the sensor press
SENSOR 1 [12] or SENSOR 2 [13] button. SENSOR 2 focus is indicated by green
SENSOR 2 [7] indicator.
When SENSOR 1 and SENSOR 2 buttons are pressed briefly together, meter switches to AUTO mode. In
AUTO mode, meter switches focus automatically to the first sensor which detects power. Activated AUTO mode
is indicated by gently flashing SENSOR 1 or SENSOR 2 indicator [7].
AUTO mode is useful for multiband HF+VHF/UHF transceivers where meter automatically switches between
sensors according to operating band (HF vs VHF or UHF). For SO2R contesting setups where only one
transceiver transmits at a time, AUTO mode is invaluable.
When SENSOR 1 button and SENSOR 2 buttons are pushed and held together for one second, meter switches
to
DUAL mode. When meter switches to the DUAL mode, it provides measurement results of both sensors at
the same time.
Please note, AUTO mode and DUAL mode availability depends on selected METER MODE. It will be described
in details later, just to not panic if you can't do it right now :-) .
BAR GRAPHS SCALES and RANGES
Bar graphs in SMΩRF are well featured and deeply customized indicators capable of displaying much more than
just power or SWR. The selection of what is actually shown on the bar graph - one of available power readings
(forward, reflected, delivered, all these variants at antenna) or parts of the complex impedance or SWR - can be
quickly set in SCREEN EDIT mode (described below). Full functionality and settings of bar graphs will be
described in separate BAR GRAPHS SETTINGS chapter, here, handling of scales and ranges is described.
At the very beginning one important note to remember. Information presented on bar graphs are always related
to one sensor, either SENSOR 1 or SENSOR 2 according to the SENSOR selection (see above). In DUAL
mode, it is possible to select whether the bar graph shows data of SENSOR 1 or SENSOR 2 individually but both
bar graphs show data of one sensor. Remote Control application on computer shows four (4) bar graphs in
DUAL mode.
Both TOP BAR [1] and BOTTOM BAR [2] has its own POWER reading scale. There are three (3) linear scales
for each in 10/20/50 full scale divisions, and five RANGE multipliers: x0.1, x1, x10, x100, x1000. Last x1000
