Product Description

DCR9910C 10A 100kΩ Transformer Core Winding DC Low Resistance Tester

Product Description

Dear Clients, Thanks for visiting Lucyelec Test Equipment. Please find more details as below:

I. Overview

The measurement of direct current (DC) resistance is a required test item for the factory test, installation and handover test of semi-finished products and finished products in the manufacturing of inductive coils such as transformer, mutual inductor, reactor and electromagnetic operating mechanism, as well as the preventive test of the power department, which can effectively identify the manufacturing defects such as material selection, welding, loose connection, missing strand and disconnection of inductive coils and the hidden dangers after operation. In order to meet the needs of rapid measurement of inductive coil DC resistance, we have developed DC resistance tester depending on our own technical advantages. The instrument adopts a new power supply technology, which features small size, light weight, large output current, wide range, digital display, two power supply modes including mains supply and internal lithium battery. The whole instrument is controlled by a single chip microcomputer and has the functions of multi-current gear selection, data processing display, discharge indication, etc. The instrument features high test precision and simple operation, which can realize the rapid measurement of DC resistance.
 

II. Safety precautions

1. It is required to carefully read the Manual before using the tester and especially follow the instructions for caution;
2. The tester can be used indoors and outdoors. But it should be avoided to use it in the rain, corrosive gases and other places. Violent vibration should be avoided for the tester so as not to affect the test data;
3. The repair, maintenance and adjustment of the tester should be completed by professionals. It is forbidden to disassemble personally.
4. The selection of test menu items should be consistent with the actual test items and wiring;
5. It is prohibited to remove the moving test clip and shut off the supply circuit in the process of testing;

III. Performance characteristics

1. The instrument has large output current and light weight.
2. The instrument provides 7 output current options, the maximum output current being 10A.
3. It is equipped with perfect protection circuit for more reliable performance, and discharge audio alarm to reduce disoperation.
4. The instrument has a wide measuring range (0.5mΩ-100KΩ), where different sample temperatures can be set, and converted resistance value can be calculated automatically.
5. The instrument can calculate the three-phase imbalance rate, providing a quick and intuitive understanding of the stability of the transformer.
6. The instrument is powered by a built-in lithium battery and equipped with an independent charging system, which is convenient for on-site operation.
7. The instrument is equipped with a 7-inch color touch screen with a resolution of 800×480 pixels. It can be configured with Chinese/English operation menus and print the output results in real time.
8. The instrument adopts two power supply modes, i.e. AC and DC, to meet the use requirements of different sites (AC and DC mode involves the same testing and wiring methods except for different power supply modes).
9. With RS232 interface, the test data can be transmitted to the backend.
10. This instrument has a powerful storage function, capable of storing up to 1000 test records.
11. With a USB interface, the test data can be transferred to a USB flash drive.
12. The parameter settings are more comprehensive, allowing for the setting of the transformer's test winding, tap position, test phase, sample temperature, converted temperature value, winding material, etc.

Panel is shown as below:


1. I+, I-: Flat cap terminals for current input/output, red for positive and black for negative.
2. U+, U-: Voltage input terminals, red for positive and black for negative.
3. LCD: 7-inch color touch LCD screen, displaying menus, current, and resistance values, etc. Avoid prolonged exposure to sunlight and heavy pressure.
4. Switch: The button switch to control the power supply of the instrument. When connected to the mains, the power supply of the whole instrument is AC; when not connected to the mains, the power supply of the whole instrument is internal lithium battery.
5. RS232: The instrument adopts a standard RS232 interface, which can be connected with the communication port of the upper computer. The instrument communicates with the PC according to the specified protocol. Both parties shall set the same baud rate and communication address to operate the instrument in real time and realize the functions of setting, measurement, data storage and transmission.
6. USB port: The connection and communication interface between the instrument and the USB flash drive is used to export memory data; the USB flash drive can be used to import data as a transfer port; the USB flash drive is connected to the computer for data transmission.
7. Printer: Miniature thermal printer, which will print test data and information when testing is completed to display or retrieve data: the printer uses 58mm thermal printing paper. When replacing the paper, open the paper compartment, insert the paper roll and leave a small portion outside, then close the cover.
8. Power socket: The instrument is connected to the mains power port and charging port.
Mains power port: The input voltage required for the instrument power supply is between AC200V and AC240V. The fuse holder is integrated with the power socket, and the fuse specification is 2A. When replacing the fuse, make sure to use a fuse of the same specification. (If the fuse still burns out after replacing it with a spare fuse, there may be a malfunction in the instrument. Please contact the manufacturer for timely assistance.)
Charging port: When the instrument is connected to the mains power, the built-in charging system starts charging the battery. Charging stops when entering the current selection interface and testing interface during use. Charging can be done normally when entering other interfaces or in shutdown state.
9. Grounding rod: Used for grounding the shell of the whole instrument, connected to the grounding wire of the power socket. Ensure reliable and independent grounding of the instrument before use. Check the grounding rod carefully for any paint or rust, as it may result in unreliable grounding.
