RMS REAL TECHNICAL EXPLANATION
• To measure the non-sine wave signal, the measure method of the real
RMS value is lower than the average value response method.
• The RMS multimeter can measure with Precision the non-sine wave
signal but to test the AC voltage or current without the AC signal input,
the multimeter shall show a reading between 1 to 50. These deviations in
readings are normal.In measuring specific ranges, the multimeter will
not be affected to measure the current or voltage Precision. The real
RMS requires an input signal to be measured to certain level so that the
c.a. voltage range and current is specified between 2% and 100 % of the
complete scale.
WORK PROPORTION
Work proportion refers to the high level within a period of time. The work
cycle proportion of a square wave is 50%, the work proportion is 0,1
justified by the level of 0,1 cycles.
The proportion of duration of positive pulses and the pulse cycle. For
example, the pulse width is 1 s, the period of sequence sign of pulses 10 s
work cycle 0,1.
MOTOR PERMANENCE ANGLE
Permanence angle is defined as the period of time it takes to make the
contacts close the ignition time. The right angle of the ignition coil can be
closed in any speed of the motor with maximum savings of energy thus
gaining better ignition. A closing that takes too long involves a contact
combustion and accelerates damage and if the contact time is too short,
causes the reduction of the ignition voltage, so that performance or
acceleration variation is reduced. RPM must be reduced after cleaning or
changing the ignition time adjustment and before closing the angle and
adjustment test.
MOTOR TACHOMETER
The idle speed in an automobile is not a tachometer speed, but a type of
work condition known as idle when the motor is idling. When the motor is
running, the accelerator pedal is completely relaxed when the motor is
idle. The tachometer speed of the motor is known as idle speed. The idle
speed of the motor is shown as idle value.La velocidad ralentí del motor se
muestra como valor ralentí.
