Overview:
The LTR-1627 double-jaw grounding resistance tester is suitable for testing the grounding resistance of various devices and building grounding devices. Such as communication equipment, telecommunication cables, equipment room, power distribution lines, transmission lines of electric towers, gas stations, factory grounding nets, lightning rods, etc., can also measure soil resistivity under various conditions. In addition to the traditional function of assisting ground pole resistance, the instrument also has the unique function of unassisted ground pole measurement, which changes the traditional measurement principle and means of testing ground resistance. The use of two-pole measurement principle and the use of double-jaw measurement technology, without the need to hit the auxiliary ground, without isolation of the grounding body and equipment, to achieve on-line measurement.
The machine has an intelligent measurement function, which can not only automatically calibrate and realize interchangeable jaws, but also store and browse measurement results.
Technical features:
1, suitable for any grounding place, non-ground contact measurement and hit the auxiliary pile double measurement method, no more or a single point of ground, can be normal testing.
2. It can be measured online. When the power equipment is used normally, there is no need to disconnect the grounding body from the equipment. Can also be measured.
3, strong anti-interference ability, since the generation of high-frequency current, so as to filter the mains in the 50Hz, 100Hz and other harmonic interference currents, even in the 500KV substation environment, can also accurately measure.
4. Automatic display of creepage resistivity without the need for tedious calculations.
5, built-in large-capacity memory, can store 100 groups of measurement data.
6, configure the charger and rechargeable battery, power saving design, automatic power off more than the specified time.
7, using four-wire measurement, the grounding resistance below 0.7Ω, but also accurate measurement.
8. The alarm will be given if the limit is exceeded or the test condition is incorrect.
9, automatic accuracy function.
Application range:
1. Communication: The power system has no auxiliary pole grounding resistance to facilitate measurement on the concrete floor.
2. Measuring the soil resistivity when constructing the ground network is conducive to the depth of construction personnel laying the ground network.
3, digital traditional resistance tester all applications (instead of traditional rocking table)
4, loop connection resistance test.

The POS Machine reads the cardholder's magnetic stripe information on the bank card through the card reader, the POS operator enters the transaction amount, the cardholder enters the personal identification information (ie password), and the POS sends this information through the UnionPay Center and uploads it. The card issuing bank system completes the online transaction, gives information on whether it is successful or not, and prints the corresponding bill. The application of POS realizes the online consumption of credit cards, debit cards and other bank cards, ensures the safety, speed and accuracy of transactions, avoids complicated labor such as manual inquiry of blacklists and pressing orders, and improves work efficiency.
