Life of soldering iron head

The life of the iron head is determined by the number of welds, and the length of life guaranteed depends on the coating thickness of the head. The thicker the coating, the longer the life of the iron head, but the heat transfer efficiency will be greatly reduced, the life of the iron tip for the same temperature series of iron head, fine iron head, life expectancy than a rough iron head life is shorter. Because the iron head is working, it will inevitably cause wear and tear on the surface of the nozzle life. Therefore, the fine iron head is more prone to wear, so to reduce the life of the soldering iron.

Maintenance of iron head

The use of new electric iron, electric iron can not bring the new use, need to be plated with a layer of solder in the iron head method is: according to the power supply when the temperature gradually increased, the rosin coated iron head; rosin smoke, to melt the solder iron head, with a the solder layer so as to strengthen the tip life.

Holdoff Range 100ns ~ 10s

Pulse Width Trigger

Pulse Width Trigger Mode Trigger when (< , >, = , or ?); Positive pulse or Negative pulse

Pulse Width Trigger Point Equal: The oscilloscope triggers when the trailing edge of the pulse crosses the trigger level.

Not Equal: If the pulse is narrower than the specified width, the trigger point is the trailing edge. Otherwise, the oscilloscope triggers when a pulse continues longer than the time specified as the Pulse Width.

Less than: The trigger point is the trailing edge.

Greater than (also called overtime trigger): The oscilloscope triggers when a pulse continues longer than the time specified as the Pulse Width

Pulse Width Range 20ns ~ 10s

Slope Trigger

Slope Trigger Mode Trigger when (< , > , = , or ? ); Positive slope or Negative slope

Slope Trigger Point Equal: The oscilloscope triggers when the waveform slope is equal to the set slope.

The Frequency Counter measures trigger source at all times, including when the oscilloscope acquisition pauses due to changes in the run status, or acquisition of a single shot event has completed.

Pulse Width Trigger mode: The oscilloscope counts pulses of significant magnitude inside the 1s measurement window that qualify as triggerable events, such as narrow pulses in a PWM pulse train if set to < mode and the width is set to a relatively small time.

Edge Trigger mode: The oscilloscope counts all edges of sufficient magnitude and correct polarity.

Video Trigger mode: The Frequency Counter does not work.
