•
‘POWER/CLEAR’ button:
Pressing the ‘POWER/CLEAR’ button clears all measurements, and re-scales the chart
if necessary.
•
‘MODE’ button:
Pressing the ‘MODE’ button once will open the mode menu, and highlight the measurement
mode currently selected; pressing the ‘MODE’ button again while the menu is open will
select the next available measurement mode. All four measurements (spark burn time,
RPM, spark plug peak voltage and dwell angle and ramp time) are simultaneously tracked
and stored, and are available for viewing at any time (without delay).
•
‘HOLD’ button:
The ‘HOLD’ button when pressed once pauses measurement and holds the display
in its current condition (while displaying a “HOLD” label in the center of the screen).
Pressing the ‘HOLD’ button a second time will remove the pause (and label), and add
a new set of values at the right of the screen, which will keep updating until the ‘HOLD’
button is pressed again. This cycle repeats every time the button is pressed twice (stop/
start) and up to the last 16 set of values will be shown in the display at once, if this
maximum is exceeded the oldest set will be deleted and a new set added.
