Screen: Bar Graph Functions - microHAM SMORF Manual

Another suffix used in provided measurements is superscripted -REF as in FWD
-REF abbreviation appears only after forward power (FWD) and stands for delivered power, power which was
transferred to the cable or to the antenna, cleared of reflected power.
-REF
FWD = (Forward Power – Reflected Power)
TX
FWD -REF = (Forward Power – Reflected Power)
ANT
How bar graphs scales and ranges work was already explained, now we look at bar graphs functions and
settings. While settings for top and bottom bar graph are almost identical, function sets available for each are
much different.
Please note, bar graph function and settings are remembered separately for each SENSOR and each
SCREEN. It means that you can have different bar graph behavior for every screen or screen copy. Anyway,
when you are happy with new settings and you want to just clone them to another screen or sensor you can copy
bar graph settings in SYSTEM MENU – SCREEN MANAGEMENT (described later).
To change function of the bar graph you have to enter EDIT mode and select field (parameter) right next to
T-BAR: or B-BAR: icon in top STATUS bar, depends on if you want to change top or bottom bar function. When
parameter is selected, you can change function by rotating the knob.
