signals, capture turn on/ turn off surges, and monitor line voltage changes over a

recording which is apt to be overflowed or to have insufficient resolution. The meter
f eatures a fast sampling speed of 50 ms for MAX, MIN and AVG readings. The
faster the sampling speed, the more accurate the measurements will be. The true
average (AVG) feature calculates all readings continually taken over time. The

rpm in the , , and Hz
function.
The selected cylinder setting or RPM setting is maintained until
the meter is turned off.
5-4. Trigger Level and +/- Trigger Slope Selection
This feature is available for RPM, Dwell, ms-Pulse, or Duty measurement function.
The meter is set at selected trigger level as power up default in individual function
as follows :
However, car signal levels under test may vary due to aging of component s,
abnormal conditions, and each car manufact urer’s diff erent design. Therefore,
positive and/or negative 4 selectable trigger levels, which are carefully designed
and tested to cover all the extreme conditions, are available in these functions to
provide more flexibility to cope with your applications.
If your reading is unstable, select lower sensitivities (higher trigger level number) by
pressing the button momentarily. If your reading shows zero, select higher
sensitivities (lower trigger level number).
