8 Hot Keys
Hot keys are used as “shortcuts” to get to a specific screen in the PowerMaster
®
. The
PowerMaster
®
3 Series supports (4) hot keys accordingly:
Waveform
Vector Diagram
Power Meter
Harmonics
When a hot key is pressed, the form will populate the screen. A hot key is accessible at ANY
time in the application. All of the function keys are accessible (F1-F6) when applicable. When
the form is on screen, the PowerMaster
®
will remember the last form the user was on before the
hot key was pressed. Once the same hot key is pressed a second time, the form will go away
and the last form remembered is re-displayed.
For all “Hot” displays pressing
also takes you back to the screen you were at before you
pressed the first hot key. It is equivalent to pressing the same hot key twice in a row.
Common Function Keys:
Instantaneous, Interval, Test Period
This function key can be found on the vector diagram, power meter, and harmonics. The main
job for this key is to allow the user to view measurements in three different time bases:
Instantaneous
: This is the default time base. Measurements are displayed every 4 cycle interval.
The PowerMaster
®
screen updates once per second.
Interval
: This is a user defined time base (currently in development). By default, values are
displayed every second. During and after a meter test, this time is based on the last meter pulse
seen.
Test Period
: This time base takes measurements until the user tells it to stop (F6). During this
time base, power is accumulated (summed) and all other signals are averaged.
Sec V, Sec I; Sec V, Pri I; Pri V, Pri I; Neutrals
This function key can be found on the waveforms, vector diagram, power meter, and harmonics.
The main job for this key is to allow the user to view different probe sets that are attached to the
PowerMaster
®
. This process may include viewing a single probe for a certain application, or it
may be to change the “power pairs” altogether.
