The DIGIAIR™ meter is intended to provide you with a spectrum view of the available off-air channels and provide
a relative strength reading which will assist in alignment of directional antennas. The default screen (on startup)
focuses on one channel, other multiple-channel presentations can be made from the main menu list.
Please take time to read this instruction manual first so you will be familiar with the capabilities of the DIGIAIR™.
The DIGIAIR™ has an internal NiMH battery which is not charged when you receive the meter.
To charge the battery, plug the wall charger or vehicle charger into the "15VDC socket on the meter. The LCD
display will indicate charging is in process with approximately 14 hours to go on the cycle. In most cases, the
battery will charge up well before the 14 hour limit of the cycle. The meter will indicate when the battery is fully
charged. The charger will not over-charge the battery as it has a timer limit as well as an internal level sensing limiter.
NOTE: If the internal battery is 'dead', connecting the wall charger or vehicle charger cord will only begin the
battery charge cycle, this will not power the meter.
After the battery has charged, press the "
button. The DIGIAIR™ is immediately ready to begin
antenna alignment. The signal strength (when
connected to an antenna) will be indicated by the bar
graph and in digits just above the bar graph. As you
move the antenna, you will see the increase and
decrease in signal strength. The objective is to
maximize the signal strength indicated on the bar graph by rotation adjustments of the antenna. Channel strength
changes are instantaneously reported while viewing this screen. When you have maximized the readings - often a
compromise between the various channels available in your area - tighten the antenna locking bolts.
Note that there are several display presentations possible with the DIGIAIR™ other than the default display shown
here. You can also select six-channel bar graphs or even all channels displayed at one time, however the single-
channel display (above) provides the most detailed information. The other possibilities available to you are
discussed in this manual on the following pages. .
