Introduction: In order to meet the needs of rapid measurement of inductive coil DC resistance, SYZ-3A developed this DC resistance tester with its own technical advantages. LCZ3A type 3A straight resistance bridge adopts new power supply technology, featuring small size, light weight, large output current, wide measuring range, digital display and internal lithium battery power supply. The whole machine is controlled by single-chip microcomputer, which automatically completes functions such as self-test, data processing and display, and has automatic discharge and discharge indication functions. The instrument has high test accuracy and easy operation, and can realize rapid measurement of direct resistance. Safety measures for the 3A straight resistance bridge tester: Be sure to read this manual carefully before using this instrument. The operator of the instrument should have general knowledge of the use of general electrical equipment or instruments. This instrument can be used indoors and outdoors, but should be used away from rain, corrosive gas, excessive dust, high temperature, direct sunlight and other places. The instrument should avoid agitation. Repair, care and adjustment of the instrument should be performed by a professional. After the test is completed, be sure to wait until the discharge alarm sound stops before turning off the power and remove the test line. To measure the unloaded voltage regulating transformer, be sure to switch the gear position after the discharge indicating alarm sound stops. It is forbidden to move the test clip and power supply line during the test. Features: 1. The instrument has large output current and light weight. 2. The instrument provides 5 output current selection, which can output 3A current. 3. The measuring range of the instrument is wide, 0-20kΩ. 4. With perfect protection circuit, the performance is more reliable. 5. Lithium-ion battery power supply, easy to operate on site. 4. LCD prompt menu operation, easy to use. 5. With sound and liquid crystal indicating discharge alarm, the discharge indication is clear, reducing misoperation. 3A straight resistance bridge tester parameters: 6.
