The correct selection and use of SF6 density relay calibrator requires following the following key steps:
1. Select a calibrator
① Clarify testing requirements: Firstly, you need to clarify your testing requirements. This includes determining the items that need to be tested, such as SF6 gas density, pressure, temperature, etc., as well as the range and accuracy requirements of the testing. If you need to test high-purity SF6 gas, you should choose instruments with high-precision testing capabilities. Meanwhile, if you need to move frequently or engage in field work, smaller and lighter instruments may be more suitable for you.
② Understanding instrument performance: When selecting a calibrator, attention should be paid to its performance indicators, such as measurement accuracy, stability, reliability, etc. High precision instruments can provide more accurate test results, while high stability and reliability instruments can ensure the smooth progress of the testing process.
③ Considering versatility: Depending on the needs, equipment that supports multiple SF6 density relays for simultaneous verification can be selected to improve work efficiency.
④ After sales service and brand selection: Choosing a brand and supplier with good after-sales service is also very important. This will ensure timely technical support and solutions when encountering problems during use.
2. Using a calibrator
① Inspection and connection: Before use, check and confirm whether all connections are correct, such as measuring pipelines, alarm locking signal lines, inflation pipelines, etc. After ensuring that the connection is correct, turn on the instrument power again.
② Function selection: Select the corresponding functional interface according to the testing requirements, such as the contact state selection interface, density relay verification interface, etc.
③ Verification operation: According to actual needs, perform locking reply value verification, locking value verification, alarm value verification, and overpressure value verification. During the operation, pay attention to following the instructions in the instrument manual to ensure correct operation.
④ Attention: During use, be careful to avoid strong vibrations to avoid affecting the accuracy and stability of the instrument. At the same time, regularly maintain and calibrate the instruments to ensure they are in good working condition.
Through the above steps, you can correctly select and use the SF6 density relay calibrator to ensure the accuracy and reliability of the test.
ZC-310 SF6 density relay tester is an intelligent SF6 gas density relay calibration instrument. The equipment adopts high-precision pressure sensors and high-speed A/D converters, combined with 32-bit high-performance microprocessors, which can perform performance verification on various SF6 gas density relays. It can accurately measure the pressure value at the current temperature when the signal acts, automatically convert the standard pressure at any ambient temperature to 20 ℃, and has printing, storage, and USB transfer functions. At the same time, it can automatically identify faults during the testing process and judge the contact status of the density relay. This product is easy to carry, easy to operate, has high testing accuracy, strong stability, and good reliability, reflecting the characteristics of the instrument as "intelligent".
