Problems solved by technology

[0003] In some application scenarios, users may need to measure multiple parameters at the same time, such as simultaneous measurement of temperature and pressure, simultaneous measurement of thermal resistance and thermocouple, etc. If there is no corresponding single device to measure multiple parameters, the user needs to operate multiple products Achieving multiple parameter measurements can be inconvenient for users
In other application scenarios, users may only need some of the functions. For example, users only need a single function of pressure measurement. If all functions or a combination of functions are configured, resources will be wasted.
Most of the existing calibrators have fixed functions. If the functions can be combined according to the needs, the user experience will be greatly improved.

Abstract

The embodiment of the invention discloses a handheld calibration instrument and a manufacturing method thereof. The handheld calibration instrument comprises a lower shell which is provided with a containing cavity with an opening, a first circuit board and an insertion assembly, wherein the first circuit board is arranged in the lower shell, and at least two first plugging ends are arranged on the first circuit board; the insertion assembly can be inserted into the containing cavity in a matched mode and comprises a cover plate and at least one second circuit board, the combination of different second circuit boards in the at least one second circuit board achieves different functions or function combinations, and each second circuit board is provided with a first end and a second end; the first end is provided with a second plug-in end which is matched and plugged with the first plug-in end, the second end is provided with a plug wire connecting port which is connected with a to-be-tested electric signal or outputs the electric signal, and the cover plate is provided with a hole corresponding to the plug wire connecting port; after the insertion assembly is inserted into the containing cavity from the opening, the second insertion end of each second circuit board is inserted into one of the at least two first insertion ends to be electrically connected with the first circuit board, and the cover plate blocks the opening and is enclosed and sealed with the lower shell into a whole.

Description

technical field [0001] The invention relates to the field of instruments and meters, in particular to a hand-held calibration instrument and a manufacturing method thereof. Background technique [0002] Process calibration instruments in handheld instruments are mainly used in high-precision measurement, detection, and calibration of temperature and pressure industrial instruments, such as on-site debugging of temperature and pressure industrial instruments and instrument factory production processes, process calibration The instrument can realize high-precision measurement and output of signals. Most of the process calibration instruments are divided into temperature and pressure. The pressure is a separate product, and the temperature is a separate product, and the functions are relatively fixed. [0003] In some application scenarios, users may need to measure multiple parameters at the same time, such as simultaneous measurement of temperature and pressure, simultaneous...
