Embodiment 1

[0024] see Figure 1 to Figure 5 , the present invention provides a process calibrator, including a housing, a light guide column 1 and a main board 10, the housing includes an upper housing 8 and a lower housing 9, and the main board 10 is fixed between the upper and lower housings 9 between; the main board 10 is provided with a plurality of input and output jacks 3, and each input and output jack 3 is provided with a corresponding indicator light 11; the jacks are horizontally arranged on the front end of the main board 10, and are provided with Corresponding to the through hole 4, when the instrument is fixed, the input and output jack 3 passes through the through hole 4 for display on the upper housing 8, which is convenient for users to identify and use. The positions of the indicator lights 11 are in one-to-one correspondence with the input and output jacks 3 . At the position corresponding to the indicator light 11 , a light guide column 1 is also arranged, and a plura...

Embodiment 2

[0033] On the basis of embodiment one, the different structures of lampshade are set, specifically as follows:

[0034] The top of the lampshade 2 is hollow so that the light can pass through. At the same time, the through hole of the lampshade 2 of the upper housing 8 is covered with a cover plate of a transparent material to prevent dust. In addition, the top of the lampshade 2 or It is the surface of the through hole of the lampshade 2 of the upper housing 8, adopting an optical lens with a light-gathering effect, or covering the interior of the lampshade 2 with a reflective layer to enhance the emission and brightness of light.

Embodiment 3

[0036] see Figure 5 , on the basis of Embodiment 1 or Embodiment 2, the structure of the lower case is improved, the back of the lower case 9 is provided with a fixed lock 14, and the fixed lock 14 is two symmetrical protrusions, Used for fixing with external support frame. In this way, when the instrument fixed on the support frame is tilted, due to the gravity of the instrument, there is a downward force on the support frame, so that the fixed lock 14 can be tightly engaged and fixed on the support frame.

Abstract

The invention provides a process check meter, which comprises a shell, a light guide post and a main board, wherein the shell comprises an upper shell and a lower shell, and the main board is fixed between the upper and lower shells; the main board is provided with a plurality of input and output jacks, and an indicating lamp corresponding to each input and output jack is arranged in each input and output jack; a plurality of lampshades for covering the indicating lamps are arranged on the light guide post, and the lampshades correspond to the indicating lamps one by one; and the main board is provided with a control circuit and an input keyboard connected with the control circuit, and the control circuit is also connected with the indicating lamps and used for controlling the indicating lamps to flicker according to the input information of the keyboard. By adopting the mode, the process check meter can prompt the input and output jacks required to be plugged in advance, so that jackconfusion produced during manual operation is avoided.

Description

technical field [0001] The invention relates to the field of instruments and meters, in particular to a process calibrator. Background technique [0002] The current detection dictionary is mainly used in the high-precision detection and calibration of industrial instruments, especially the on-site debugging of industrial instruments and the use of calibration instruments in the production process of instrument factories. It is characterized in that it mainly includes input test leads, output test leads, input sockets, output sockets, windows, operation buttons, etc., which can realize high-precision detection and output of analog signals; in actual use, the existing detection dictionary, because the input and output sockets Many, and designed together, only use characters to remind the user to insert the signal into the socket, it is easy to insert the test pen into the wrong socket due to misreading the characters, thus burning out the I / O interface of the test book and ma...
