Talking about the calibration environment and equipment requirements of the wrist strap online tester

Wrist strap online testerIt is an important device for testing anti-static wristband equipment. It can judge whether these devices can work normally, so it is widely used in some high-precision equipment, national defense and other fields. With the attention of all walks of life to anti-static, the application frequency of wrist strap online tester is increasing, and the requirements for its test accuracy are getting higher and higher. Therefore, it will be calibrated every certain period of time, and before the calibration , The calibration environment and equipment need to be configured.

Environmental requirements for calibration: The wrist strap online tester has very high requirements for the laboratory environment to be calibrated. The laboratory environment is very important. It will have a very important impact on the calibration results of the tester. The inaccurate detection of the anti-static wrist strap will cause the human body to leak static electricity, which will affect the production activities and, in serious cases, will damage the production equipment and products. Therefore, it is necessary to strictly control the calibration environment. According to relevant practices, the laboratory temperature is generally controlled at 20℃~25℃, and the humidity is generally controlled at 40%~60%. In addition, it should be noted that the wrist strap is online Before calibrating, the tester needs to be placed in the laboratory for 8 hours before calibrating.

Equipment used for calibration: At present, the equipment for calibration of the wrist strap online tester generally uses a continuously adjustable resistance box. The resistance box should first be a qualified product, with a certificate of relevant qualification certification, and its resistance value range should be greater than the anti-counterfeiting of the tester, otherwise it cannot be calibrated. In addition, the allowable error, stability, and resolution of the resistance box should be better than the wrist strap online tester.
