Abstract
The utility model discloses a dual-purpose multimeter which comprises a multimeter body. The multimeter body is formed by a meter head, an adjusting knob and a testing connection port, wherein the testing connection port is in electrical connection with the adjusting knob, the meter head is provided with an indicator type display panel, a digital displayer and a three-section adjusting switch, the indicator type display panel and the digital displayer are respectively in electrical connection with the adjusting knob through the three-section adjusting switch, and the indicator type display panel, the digital displayer and the three-section adjusting switch are all embedded on the upper surface of the meter head. The dual-purpose multimeter is simple in structure and high in measuring reaction sensitivity and accuracy, effectively overcomes the shortcomings that indicator type multimeters are low in sensitivity and digital type multimeters are unstable in reading, effectively reduces measuring time and improves working efficiency.
Description
Technical field
The utility model relates to a kind of dual-purpose multimeter, belongs to electric power testing tool field.
Background technology
The survey instrument of indispensability when multimeter is the low-voltage circuit detection, multimeter commonly used is divided into pointer-type and digital according to its reading mode at present, all there is certain deficiency in the multimeter of these two kinds of forms, pointer multimeter stable reading but to measure sensitivity not high, digimer measures highly sensitive but reading is unstable, has certain deviation, therefore, in actual use, often need to same objective circuit take multiple measurements to guarantee reading accurately, work efficiency relatively under.
Summary of the invention
The utility model purpose just is to overcome above-mentioned deficiency, and a kind of dual-purpose multimeter is provided.
For achieving the above object, the utility model is to be achieved through the following technical solutions:
A kind of dual-purpose multimeter, comprise the multimeter body, described multimeter body is made of gauge outfit, adjustment knob and test connector, and test connector and the electrical connection of adjustment knob, described gauge outfit is established pointer display panel, digital display device and three sections by-pass cockes, described pointer display panel, digital display device are electrically connected with adjusting knob respectively by three sections tune switches, and described pointer display panel, digital display device and three sections tune switches all are embedded in the gauge outfit upper surface.
The utility model is simple in structure, and it is high to measure reaction woods sensitivity and degree of accuracy, has effectively overcome the low and unsettled deficiency of digital reading of pointer sensitivity, thereby has effectively reduced the measurement number of times, has improved work efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
