4. BUTTONS, ICONS AND MENUS OPERATION 4.1 ‘POWER/CLEAR’ button • When the instrument is OFF, to turn it ON press and hold the ‘POWER/CLEAR’ button until the unit turns on (in approximately 1 second). • When the instrument is ON, to turn it OFF press and hold the “POWER/CLEAR’ button until the display turns OFF (in approximately 3 seconds). • When the instrument is ON, press the ‘POWER/CLEAR’ button to clear all measurement data, and start a new measurement.
4.3 ‘MODE’ button and menu The ‘MODE’ button allows the selection of the type of measurement to be shown in the display. Upon pressing this button a pull down menu will open with the current setting highlighted, To change the setting press the ‘MODE’ button repeatedly until the desired setting is highlighted, then wait until the pull down menu closes. The new current setting will be displayed as the mode icon at the top of the screen.

Waveform (i.e. oscilloscope) view. 4.5 ‘HOLD” button · When chart, digital or waveform display mode is selected, pressing the ‘HOLD’ button will pause the measurement, hold the current display, and the word “HOLD” will be shown in the measurement area of the display to indicate this status.
5. MEASURING MODES There are four different ignition system parameters that can be selected for measurement, depending on the engine’s ignition system: • Engine RPM. • Spark burn (firing) time. • Spark plug voltage. • Dwell angles (for ignition systems equipped with high voltage spark plug wires). • Primary ignition coil current ramp time (for coil on plug and coil near plug ignition systems). 5.
6. DISPLAY VIEWS There are four views that can be selected to display measurements: • Chart • Comparison • Digital • Waveform 6.1 Chart view This view displays the selected measurement’s value corresponding to each of the last 276 sparks, with the left most measurement being the oldest, and the rightmost the newest. The measurement scale and units are located on the vertical axis, at the far left of the display.

• ‘POWER/CLEAR’ button: Pressing the ‘POWER/CLEAR’ button clears all values in the graph, and re-scales the gauge 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.
7. MEASUREMENT PROCEDURES CAUTION To avoid personal injuries and damage to the instrument carefully inspect the spark plug wires, distributor cap, ignition coil , ignition module, and all other ignition system parts for damage or leaks, and avoid using this instrument in case any damage or leaks are found. Never touch the capacitive pick-up or flexible probe during a test.
COP pick-up Ignition module Fig. 11 - Using the COP pick-up on a ignition module 6- If the instrument is unable to detect the ignition system signal, it may be necessary to reposition the pick-up so that a consistent signal is detected and displayed. NOTES • The position of the pick-up and the particular design of the ignition module may affect the signal’s shape shown when the waveform display is selected.
NOTES • The absolute spark plug voltage reading will depend on the position of the pick-up, the particular characteristics of the wire, etc.. Therefore the placement of the pick-up relative to the wire should be keep as consistent as possible for all the measurements in order to compare voltage readings between several cylinders’ spark plug wires.
6- If the instrument is turned on (by pressing the ‘POWER/CLEAR’ button) at any time while connected to the power adapter, the instrument will display the charging status . 7- The USB type A connector can be also plugged into a USB port of a personal computer, powered USB hub, or any other USB compliant power source. 5- The recharge time will depend on the state of charge of the battery, and it may take up to 6 hours to fully recharge a depleted battery.
