or
“F1 /Calibrate” (Cylinders Decrease ) button to adjust the scale value.
3.5 Additional functions
3.5.1 Minimum and Maximum functions
(For COP and SPW modes)
This instrument remains the record of the minimum and maximum readings of the
function currently selected.
1- In order to display the minimum and maximum readings of the main display,
press the
“
F2
”
button if not already selected.
2- In order to reset the minimum and maximum readings, press the
“
Power /Reset
”
button momentarily. These values will be reset after turning on the instrument.
3.5.2 Spark KVolt calibration function (For COP mode only)
In order to measure the spark KVolt in Coil on Plug and Coil near Plug ignition
systems, this instrument requires the user to calibrate the instrument. This calibration
uses the measurement values obtained during the procedure to find the optimal
measurement parameters or a particular type of the ignition module, and
compensates for the difference in waveform and signal strength.
◆
Once the instrument calibrated one of ignition modules of the engine under test,
the spark KVolt measurement will relative to the calibration value.
◆
Follow the procedure as described in
“3.4.2 Measuring in Coil on Plug and Coil
near Plug ignition systems
” to calibrate the instrument.

– Display during calibration
Notes:
◆
The instrument will display the default baseline value of
“10.0 spark KVolt”
immediately after calibration. All the spark KVolt measurements obtained thereafter
will relative to the calibration value module.
◆
The calibration does not have any influence on the spark burn time or the PRM
measurement. (These are absolute).
◆
The Spark KVolt values obtained before and after calibration may not be
comparable if calibrate the instrument again.
◆
The instrument will display a false
“0.0 Spark KVolt” reading when measuring the
spark KVolt on Coil on Plug and Coil near Plug systems if not calibrated.
3.5.3 Auto power off
In order to prolong the battery life, the instrument will automatically power off after
