Recently, our regional sales manager made a special trip to Zaoyang, Hubei to visit old customers.

    After arriving at the destination and having a brief chat with the customer, the sales manager conducted an investigation and return visit on the use of the equipment previously purchased by our company. Then led by the customer to the equipment room, the customer manager carefully checked the performance of each equipment.

    During the face-to-face communication with the customer, the customer reported that some tests needed on-site retraining and guidance. The sales manager listened carefully to the customer's questions and explained the problems encountered in detail. The customer listened carefully and recorded them one by one. Afterwards, a series of operations such as booting, wiring, and setting parameters are demonstrated again.

    During the operation, the performance of the equipment was also checked, the instrument was running smoothly, and the product quality was once again recognized by customers. And said that in the future will continue to carry out in-depth cooperation!

    Today, let's introduce our NR5300 loop resistance tester!

    Features
    NR5300 loop resistance tester, also known as contact resistance tester, is mainly used to measure the contact resistance of the main contacts of various high and low voltage circuit breakers (referred to as switches), and can also test high and low voltage cable lines, busbars, welds and any ultra-low voltage The resistance value of the non-inductor, etc.
    This instrument is strictly in accordance with the latest standard "JJG1052-2009 Loop Resistance Verification Regulations" GB50150-91 and DL/T596-2021. It can output a stable current of no less than 100A for a long time, avoiding the inability of the instrument to work continuously and thus not be able to effectively hit The disadvantages of wearing "oxide film".
    The combination of new power supply and precision measurement control circuit makes the measurement data have high precision and good repeatability.
    This instrument has the functions of automation and simple operation. It only needs to press a button to automatically measure the data without manual adjustment, which avoids the instability of the data generated by the operator in the process of adjusting the current, and greatly improves the use efficiency.
