Product Introduction
at present the contact resistance measurements of the conventional type QJ44 arms widely used in electric power system DC bridge and the Test of this kind of bridge current only mA level it is difficult to find circuit conductor cross-sectional area to reduce defects when measuring contact resistance high-voltage switch electric circuit due to the contact between the oil film and the influence of the oxide la
Contact resistance tester is designed according to the People's Republic of China electric power implementation standard DL/ t845.4-2004 using high frequency switch the power supply technology and digital circuit technology combined.Contact resistance tester is applicable to the measurement of circuit resistance of switch control device.Its Test current USES 100A and 200A DC recommended by national standards.the circuit resistance can be directly measured at the current of 100A or 200A and the final test results are displayed in figures.the instrument is accurate in measurement and stable in performance. It meets the requirements of high voltage switch maintenance and resistance test of high voltage switch factory circuit.
Product names: Contact resistance tester, switchMicro Ohmmeter, Contact Micro Ohmmeter contact (circuit) resistance tester

Product Characteristics
1, High current: using the new power supply technology Contact resistance tester can continuously output high current for a long time overcome the disadvantage of impulse the power supply instantaneous current can effectively break through the switch Contact oxidation film get good test results
2, Strong anti-interference ability: under the condition of serious interference the last digit data of LCD can be stable within ±1 word of the scope of with stable reading and good repeatability
3, Long service life: all use high precision resistance effectively eliminate the influence of the environment temperature on the measurement results at the same time the use of military connector enhances the anti-vibration performance
4, Easy to carry: small volume, the weight of the weight of the weight
