Use of inductive load DC resistance tester and classification test method

Inductive load DC resistance tester takes high-speed microcontroller as the core, adopts high-speed A/D converter and programmable current source technology to achieve unprecedented measurement effect and highly automated measurement function, with high precision, wide measurement range, and stable data. Good repeatability, strong anti-interference ability, perfect protection function, fast charging and discharging, etc.

Cautions for the instrument 1. Be sure to reset before measuring the back-to-back tap changer of the no-load regulator. After the discharge is completed, the discharge prompt tone is over, and the prompt message disappears and then the tap changer is switched.

2. After the test is finished, press the "Reset" button. Be sure to wait until the discharge indicator goes out. After the message disappears, turn off the power and remove the line.

3. Please cut off the power or test the clamp off during the test.

4. Please connect the ground wire before turning on the power, and finally remove the ground wire after the test.

Classification test method A: DC power test: Close the main power switch, the corresponding indicator light, press the "start and stop" button, you can test. After the test is completed, press the "reset button", the instrument displays "is in the discharge", and other instruments return to the boot interface, turn off the main power switch, the corresponding indicator light goes out, and then convert the test clip to conduct another test.

B. AC power test: Connect the AC220V power supply. The "charge" indicator light is on. Close the main power switch. The corresponding indicator light is on. Press the "Start and stop" key to test. After the test is completed, press the "reset button", the instrument displays "is in the discharge", and other instruments return to the boot interface, turn off the main power switch, the corresponding indicator light goes out, and then convert the test clip to conduct another test.

Niobium metal turns blue when left at room temperature for a long time. Although its elemental state has a higher melting point (2,468 ° C), it has a lower density than other refractory metals. Niobium is resistant to many acids and alkalis.
Niobium is less electropositive than zirconium on its left. Its atomic size and Tantalum atoms located below it are almost the same, which is caused by the lanthanide contraction effect. This makes niobium chemically very similar to tantalum. Although its corrosion resistance is not as high as that of tantalum, it is cheaper and more common, so it is commonly used as a replacement for tantalum in less demanding applications, for example as coating material in chemical plant tanks.The Melting Niobium is a kind of primary material, which can be used as an additive in the production of iron and steel. And the melting niobium is the best choice for the production of Niobium Ingot. Compare with the niobium strip, the smelting niobium can make the better niobium ingot.

BT Alloy Co.,Ltd. was founded in 2005 with a strong financial foundation, a sound system ofpersonnel and system management. The company is located in 205 Century Road,Dawukou Area, Shizuishan,Ningxia Province, China, and mainly produceand sale related Ta, Nb, Be and Graphite, Al products, semi-finished products. Afteryears of development, the company has two factories, which covers an area ofmore than 40000 square meters, with professional facilities and personnel.

Companiesadhering to the scientific management of modern enterprises, the production ofprecision, forge ahead, pioneering and innovative, rapid rise to the strengthenterprises in the local market.
