Zc-630 three-phase harmonic analyzer adopts key type operation, can automatically switch the measuring range, maintain the measured data, store the measured data, realize large capacity storage, and output vector diagram, which is very suitable for differential detection and start-up test field use such as electric energy measurement, power inspection, substation maintenance, relay protection, etc.
When using zc-630 power harmonic analyzer, the following safety precautions shall be taken to avoid personal injury and damage to the product or any other connected products. Only qualified technicians can carry out maintenance and operation.
1. As a safety measure, the instrument is equipped with protective grounding terminal. Before the test, the grounding terminal on the side of the device shall be reliably grounded.
2. Prevent falling: do not place the instrument on an unstable platform or desktop to prevent the instrument from falling and damage.
3. Use appropriate power cord: use 220VAC, 50 / 60Hz power cord with current of 10a and above.
4. Ensure good heat dissipation: the fan and ventilation hole on the side of the instrument are set for ventilation and heat dissipation, please do not block them.
5. Prevent short circuit: do not let any foreign matter fall into the chassis to avoid short circuit.
6. Connect and disconnect correctly: do not connect or disconnect the test wire when the equipment is under test.
7. Do not operate without cover plate: if the cover plate or panel has been removed, do not operate this product.
8. Use appropriate fuse: 12a fuse is used for this equipment.
9. Avoid contact with exposed circuit and live metal: do not touch exposed contacts and parts when the product has power.
10. Do not operate in case of suspected fault: if the product is suspected to be damaged, please check it by the company's maintenance personnel and do not continue to operate.
11. Operating environment: do not operate in humid or explosive environment.
12. This instrument is a precision electronic instrument. Please pay attention to prevent the high temperature environment such as sun exposure when using outdoors, and do a good job in blocking the sun and ventilation, so as to prevent the instrument from overheating or reducing the measurement accuracy.
13. Product transportation: during transportation, please lay buffer protection such as sponge on the outside of the instrument, so as to avoid damaging the instrument or reducing the accuracy of the instrument due to vibration and turbulence.
Finally, I would like to remind you that in order to avoid possible dangers, zc-630 power harmonic analyzer can only be used within the specified range. If there is something you don't understand, please contact our online customer service for details.
