DISPLAY PANEL KEY DESCRIPTIONS
FREQUENCY KEY
When the Freq. key is pressed, the display shows the
output frequency setting (
Fig.2.1
). Pressing the Arrow
keys allows the user to change the output frequency.
Pressing the Enter key selects the settings and returns
you to the status screen. The range of this control is from
1Hz to 120Hz in 1Hz increments. Pressing 'Freq.' a second
time will abort this function and return to the status
screen. Pressing another function key (other than the
Arrow keys) will abort this function and move you to the
setup display for the key that was pressed.
DUTY CYCLE KEY
When the Duty Cycle key is pressed, the display shows
the output duty cycle setting and pulse width in
milliseconds. Pressing the Arrow keys allows the user
to change the output duty cycle (
Fig. 2.2
). Pressing
the Enter key selects the settings and returns you to the
Status Screen. The range of this control is from 1% or 0.1
milliseconds, whichever is larger, to 99% in 1% increments.
Pressing the Duty Cycle key a second time will abort this
function and return you to the Status Screen. Pressing
another function key (other than the Arrow keys) will
abort this function and move you to the setup display
for the function key that was pressed. Duty cycle is the
percentage of time the output pulse is on over a one
second period. For example, if the selected waveform
is 60 Hz with 25% duty cycle, an output pulse will occur
60 times per second (once each 16.7 mSec) with a pulse
width of 0.25 X 16.7 mSec. = 4.2 mSec, and a gap between
pulses of 0.75 X 16.7mSec. = 12.5mSec.
