Abstract

The invention discloses an electrical detection instrument and a method thereof, comprising an instrument panel, a positive instrument connection terminal, and a negative instrument connection terminal, one end of the instrument panel is connected to a first circuit, and the other end is connected to a second circuit; the first circuit A first on-off structure is set between the positive instrument terminal to switch the first circuit in the on-off state, and a second on-off structure is set between the second circuit and the negative instrument terminal to switch the second circuit in the on-off state .

Description

technical field [0001] The invention belongs to the technical field of testing, and in particular relates to an electrical testing instrument and method. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] Electrical instruments such as voltmeters, ammeters, and frequency meters are widely used, covering almost all industrial processes and scientific research fields. Monitoring, the status of these instruments is directly related to the normal operation of the entire system, so the regular measurement of these instruments is particularly important. [0004] The working method of electrical instruments is to connect to the monitored working circuit in series or parallel, and read electrical parameters such as voltage and current in real time. When measuring electrical instruments, it provides standard electrical signals through a multi-function calibration source....
