Abstract

The invention provides a medical electric leakage analyzer calibration device and system, and belongs to the technical field of calibration equipment. The device comprises a control module, a small signal generation module connected with the control module, and an amplification output module connected with the small signal generation module. The amplification output module is used for being connected with a medical electric leakage analyzer to be calibrated. The control module is used for generating a calibration instruction to the small signal generation module. The small signal generation module is used for generating a high-frequency sine wave signal corresponding to the calibration instruction and having the bandwidth being in a preset frequency range according to the calibration instruction. The amplification output module is used for amplifying the high-frequency sine wave signal at a preset multiple to obtain a calibration signal. When the medical electric leakage analyzer to becalibrated is calibrated through the calibration signal, the bandwidth of the calibration signal is within 10 Hz to 10 MHz and is also amplified by a preset number, so that the calibration signal generated by the calibration device of the medical electric leakage analyzer meets the calibration requirements of the medical electric leakage analyzer to be calibrated no matter the bandwidth and the power.

Description

technical field [0001] The invention relates to the technical field of calibration equipment, in particular to a calibration device and system for a medical leakage analyzer. Background technique [0002] As early as 2007, my country has issued the verification regulations for medical leakage analyzers or similar equipment JJG843-2007 "Verification Regulations for Leakage Current Testers". The verification regulations stipulate that when calibrating the medical leakage tester, the measurement frequency range of the calibration device is required to reach 10MHz, the load reaches 2kΩ, and the load current reaches at least 20mA. Although the parameters of the instrument are stipulated in the verification regulations, the existing instruments and equipment on the market are difficult to meet the requirements of the standard in the specification. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a medical leakage analyzer ca...
