摘要: An electric meter having a detachable measuring bar includes a main body, a first measuring bar and a second measuring bar assembly. One end of the main body is formed with a supporting portion. The first measuring bar has a connecting portion and a probe formed at the other end of the connecting portion. The connecting portion is detachably connected with the supporting portion of the main body. The second measuring bar assembly comprises a second measuring bar and a lead. Both ends of the lead are connected to the main body and the second measuring bar. Via this arrangement, when the first measuring bar is worn or damaged in use, the first measuring bar can be replaced, thereby reducing the purchasing cost of the electric meter.

摘要: A detecting device for fuel injecting interval is provided, more particularly, to a portable and digital detecting device for detecting the fuel injecting interval of the injector of engine. The detecting device comprises a level transformer, a signal delay filter, a digital signal processor, and a display. The input of the level transformer 2 is electrical connected to the output load terminal of the controller 1 of the injector of engine in a way of inverse measure. The high frequency noise in the target waveform is filtered by the signal delay filter. The delay time within the detecting device is calculated by the digital signal processor and is subtracted. The resulted and exact fuel injecting interval is illustrated in the display. The detecting device features a compact configuration, easy to maintain and low service cost. Most important, the detecting device features a lower measuring error level.
