The terms "first," "second," and the like in the description and claims of this application or in the foregoing drawings are used for distinguishing between different objects and not for describing a particular sequential order.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

Example 1

A dial plate is characterized in that scale marks 206 and a plurality of range indicating lamps 202 used for indicating corresponding scales on the scale marks are arranged on a dial body 2, and the range indicating lamps 202 are uniformly distributed on one side of the scale marks 206. The tray body 2 is further provided with two mode lamps 201 and a key 204, wherein the key 204 is used for switching a range mode and displaying a corresponding range mode through the mode lamps 201.

When implementing, the dial plate of this application is applied to on current detection record appearance 1, and wherein, current detection record appearance 1 embeds has main control panel 3, and mode lamp 201 and range pilot lamp 202 are controlled by main control panel 3 respectively, and button 204 is connected with main control panel 3 electricity.

More specifically, in practice, the two mode lights 201 are a red light emitting diode and a green light emitting diode, respectively. The range distinction is more striking through distinguishing the colors again.

As shown in fig. 1, a display screen 203 is installed in the middle of the tray body 2, and a signal input end of the display screen 203 is connected with a signal output end of the main control board 3. The detection value can be displayed through the display screen 203, and is compared with the pointer indication value, so that detection errors are avoided.

In implementation, the range indicator lamp 202 is configured as an LED lamp bead. As shown in fig. 5, a main control chip (single chip microcomputer) is arranged on the main control board 3, and the main control chip is connected with the plurality of LED lamp beads through a serial bus. The main control chip can enable the range indicator lamp 202 to simulate the running water lamp working mode to perform numerical indication.

In implementation, the scale lines 206 include a first scale line corresponding to ampere and a second scale line corresponding to milliampere, specifically, the measurement ranges on the current detection recorder 1 are 0 to 2A and 0 to 400mA respectively, and a measurement range indicator 202 is installed at the positions of the scale lines represented by 0.25A (50 mA), 0.50A (100 mA), 0.75A (150 mA), 1.00A (200 mA), 1.25A (250 mA), 1.50A (300 mA), 1.75A (350 mA) and 2.00A (400 mA) on the scale respectively.

When in use, the detection range is selected to be 0-2A:

when the detected value is greater than 0.25A, the range indicator lamp 202 at the position of 0.25A on the scale is on;

when the detected numerical value is greater than 0.50A, the range indicator lamp 202 at the positions of 0.25A and 0.50A on the scale is on;

when the detected numerical value is greater than 0.75A, the range indicator lamp 202 at the positions of 0.25A, 0.50A and 0.75A on the scale is on;

……

by analogy, when the value is larger than the value representing the scale, the previous range indicator lamp 202 is on, so that data can be estimated according to the number of the range indicator lamps 202, and the method is very convenient.
