USING THE POWERMASTER II – Front Panel Controls - General Operation
In addition to the large (4x1") LCD display, VSWR and Power Alarm LEDs,
there are two buttons on the front of the PowerMaster II: "Menu" and "Mode
Select."
These buttons are used to select the operational mode and to program the
meters' many functions such as VSWR Alarm, Power Monitor Alarm, Auto
Ranging Bar Graph Scales, etc.
Operation Menus - A tour of how to operate your Power Master II
Note: Along with the image directly above, some of the illustrations in this manual are of the original Power Master and where it is not critical, we have not
used photos of the Power Master II. In these cases, the menus and displays shown are virtually identical in both the Power Master and the Power Master
II.
PowerMaster II RF Wattmeter
The following discussion shows you how to operate the meter. As we add
more features, you will be able to download more options for your meter from
the Array Solutions Website. You are invited to join the Array Solutions
User's Group which can be found on the Array Solutions website.
After Power-Up the meter enters the Normal Operation Mode – see
upper left character for mode selection
Push the mode select button to scroll through the 5 modes of operation:
F – Fast release of peak hold, ~0.2 second
M – Medium retention of peak hold, ~1 second
S – Slow release of peak hold, ~2 seconds
L - Long peak hold - ~5 seconds
V – Reflected Power is displayed on the Bar Graph – see next image
Peak power in digits is always displayed in the upper right corner and SWR
is displayed in the middle of the upper line of the display (V _.__)
VSWR Bar graph Mode
Used to allow easy adjustment of a tuner for minimum VSWR. In this mode,
the bar graph is displaying reflected power. Reduce the amount of deflection
(or "dip") for minimum VSWR. (Original Power Master Image)
Note: The VSWR is still displayed in digits here in the middle of the top row –
in this photo the SWR is 1.33:1, displayed as (V 1.33).
