Abstract
The invention discloses a pointer type multimeter. The multimeter comprises a multimeter head part, a panel and multimeter probes. The multimeter head part is arranged at the top of the pointer type multimeter, and the panel is arranged below the multimeter head part. A mechanical zero setting rotary knob is arranged at the top of the panel, audion test holes are formed in one side of the lower portion of the mechanical zero setting rotary knob, a positive pole inserting hole and a negative pole inserting hole are formed the positions below the audion test holes, an Ohm zero setting rotary knob is arranged on the other side of the mechanical zero setting rotary knob, and special inserting holes for a specific shift range are arranged below the Ohm zero setting rotary knob and are the 2500 V special inserting hole and the 10A special inserting hole. A circular change-over switch is arranged in the center of the panel. Each multimeter probe is composed of a metal needle, a casing, a copper wire and a plug. The metal needle is connected with the corresponding plug through the corresponding copper wire. The multimeter head has a strong burnout resistant function, the multimeter damage caused by errors is reduced, and maintenance difficulty is avoided. In this way, the multimeter head part has high sensibility, and can precisely display readings of a tested circuit and reduces the errors in reading.
Description
Technical field
The present invention relates to a kind of universal meter, more particularly, to a kind of pointer multimeter.
Background technology
Now, in a lot of industries, especially in electric operation industry, even in our huge numbers of families, universal meter
A requisite survey tool, this just be enough to find out universal meter in our life in occupation of very big status, ten thousand
It is even more the core of a universal meter with the gauge outfit of table, be directly connected to the certainty of measurement of universal meter, but, gauge outfit part again simultaneously
It is the part that universal meter is easiest to damage, under existing technology, usually have a lot of people's meetings because imprudence when using, in mistake
Measure on gear, then the consequence leading to this when is exactly blown out, be followed by burning gauge outfit by mistake, and one
Denier gauge outfit is burnt it is possible to declare that this universal meter has been scrapped, main cause be also because repairing comparatively laborious, with
When also have certain cost expenditure, a certain degree of inconvenience is caused on some angles.
Content of the invention
In order to overcome existing various deficiency, it is an object of the invention to provide a kind of pointer multimeter, this pointer-type ten thousand
Have stronger resistant to damage ability with the gauge outfit of table, will not easily burn out, though measurement during make a mistake it is also possible to
To react to operating personnel's time enough, it is to avoid the final selection changing universal meter occurs.
The technical solution adopted in the present invention is：
A kind of pointer multimeter, including gauge outfit part, panel and test pencil, described gauge outfit part is actually a sensitivity
Very high DC ammeter, described table header sets up the top in described pointer multimeter separately, and described panel is located at gauge outfit part
Lower section, the top of described panel is provided with machine zero knob, is provided with three poles in the lower section side of described machine zero knob
Pipe instrument connection, below described triode instrument connection "+" socket and " " socket, the opposite side being provided with machine zero knob is provided with Europe
Nurse returns to zero knob, and described ohm returns to zero the special jack of lower section special gear range of knob, be respectively the special socket of 2500V and
The special socket of 10A, the centre being provided with described panel is provided with a circular change-over switch, described test pencil by metal needle, shell,
Copper wire electric wire and plug composition, described metal needle is connected with described plug by described copper wire electric wire, the side of described universal meter
Equipped with fuse, after be provided with battery case, described battery case is externally provided with screw.
It is provided with permanent magnet in described gauge outfit, between described permanent magnet, is placed with the pole palm, the inside of the described pole palm is provided with iron core,
It is provided with movable coil between the described pole palm and described iron core.Described movable coil is provided with axle bed, and described axle bed is provided with pointer,
