Description
Technical field
The utility model belongs to measurement instrument field, is specifically related to a kind of multimeter with alternating current measuring ability.
Background technology
Multimeter is the instrument being mainly used in measuring electrical quantity, existing multimeter can complete and measure the electrical quantity of AC and DC, have both some other functions simultaneously, such as measuring resistance, survey diode and the function such as triode polarity and measuring tempeature, this makes the function of multimeter from strength to strength, and usage range is more and more wider.
When function of multimeter from strength to strength, its single display unit is but unvalued part.Most of multimeter is all the display mode of segment liquid crystal on the market, and the great advantage of this mode is low in energy consumption, and shortcoming is that display according to the displaying contents display determined during prior die sinking, can only lack versatility and dirigibility.In addition, most of segment liquid crystal display does not have backlight, substantially cannot see indicating value, which has limited its range of application under the environment of insufficient light.
Utility model content
The purpose of this utility model is to provide a kind of multimeter of automatic light source, can adapt to dim environment operation, also has shatter-resistant function simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of multimeter with alternating current measuring ability, comprises gauge outfit, governor circuit, metering circuit, power supply, switch and watchcase, and described gauge outfit comprises OLED display screen; Described power supply comprises the power circuit of driving OLED display screen luminescence; Signal wire and the described governor circuit of described OLED display screen are electrically connected; Described watchcase comprises the table window for installing described OLED display screen; Four limits of described OLED display screen are bonding with described table window; Described table is also bonded with transparent nerd pack outside window; The left and right sides in described watchcase front is arranged with the anti-skidding striped of some projections.
Preferred: described power acquisition 3 joint 1.5V dry cell series-feds.In order to ensure that the reading that OLED display screen shows has enough brightness, add a joint dry cell, to meet the power consumption demand of OLED display screen.
Preferred: the rubber protecting jacket also comprising band cavity, described watchcase embeds in the cavity of described rubber protecting jacket.Rubber protecting jacket not only has the effect of buffering shatter-resistant, but also has the effect of certain waterproof, protection against the tide, dust protection, thus extends the serviceable life of multimeter, improves the stability of multimeter performance.
The utility model has following beneficial effect: OLED display screen has self light emission function, and reading is automatic luminous when showing, and does not need backlight, can adapt to dim environment operation.And OLED display screen has built-in electronic circuit system, therefore each pixel is by a corresponding signal wire drive, so just can demonstrate various image, and according to the displaying contents display determined during prior die sinking, versatility and the dirigibility of display can only be improve unlike LCDs.In addition also to have contrast high for OLED display screen, the advantages such as thickness is thin, visual angle is wide, reaction velocity is fast.Anti-skidding striped can strengthen the friction force holding multimeter, prevents multimeter landing from hand, plays the effect of shatter-resistant.
Accompanying drawing explanation
Fig. 1 is circuit structure block diagram of the present utility model;
Fig. 2 is external structure schematic diagram of the present utility model.
Embodiment
As shown in Figures 1 and 2, a kind of multimeter with alternating current measuring ability, comprise gauge outfit, governor circuit 1, metering circuit 4, power supply 2, switch 3 and watchcase, described gauge outfit comprises OLED display screen 5; Described power supply 2 comprises the power circuit of driving OLED display screen 5 luminescence; Signal wire and the described governor circuit 1 of described OLED display screen 5 are electrically connected; Described watchcase comprises the table window for installing described OLED display screen 5; Four limits of described OLED display screen 5 are bonding with described table window; Described table is also bonded with transparent nerd pack 6 outside window; The left and right sides in described watchcase front is arranged with the anti-skidding striped 7 of some projections.Anti-skidding striped 7 can strengthen the friction force holding multimeter, prevents multimeter landing from hand, plays the effect of shatter-resistant.
Metering circuit 4 comprises signal that institute handlebar needs measure and converts the digital signal that governor circuit 1 can identify to, and then governor circuit 1 is reduced into the actual value needing measuring-signal through certain computing formula according to digital signal.When switch 3 is switched to different measurement functions, metering circuit 4 needs the metering circuit of measuring-signal by being switched to correspondence, and governor circuit 1 also calls corresponding calculation procedure according to the gear of switch 3, but also control OLED display screen 5 is demonstrated the Chinese information of respective notch function.
Such as, when measuring alternating current, metering circuit 4 comprises alternating current testing circuit, concrete alternating current testing circuit can with reference to prior art, because be not the core that the utility model improves, turn round and look at and do not repeat at this, switch 3 is switched to alternating current shelves, the alternating current signal detection circuit of metering circuit 4 correspondence plays a role, AC signal is converted to digital signal, now governor circuit 1 receives digital signal and passes through and calculates actual AC current values, and value is shown in OLED display screen 5, simultaneously by clear and definite display " alternating current " printed words, indicate the meaning of now measured value.In OLED display screen 5, all parts that can show are all luminescence displays, in dark conditions can be high-visible; In addition, OLED display screen contrast is high, even if also can be high-visible under the strong environment of light.
Preferred: described power supply 2 adopts 3 joint 1.5V dry cell series-feds.In order to ensure that the reading that OLED display screen shows has enough brightness, add a joint dry cell, to meet the power consumption demand of OLED display screen.
Preferred: the rubber protecting jacket also comprising band cavity, described watchcase embeds in the cavity of described rubber protecting jacket.Rubber protecting jacket not only has the effect of buffering shatter-resistant, but also has the effect of certain waterproof, protection against the tide, dust protection, thus extends the serviceable life of multimeter, improves the stability of multimeter performance.
