To Mao DLB-LR resistance box resistance voltage tester purely resistive load bank test for the detection of this type of resistance box resistance voltage tester leakage current, capacity specially developed, good stability! Compliance with the withstand voltage tester verification procedures. Second, use a voltage tester to test resistance, leakage current and capacitance. Accuracy, stable performance, lightweight portable, easy to operate. Third, the standard conditions at a temperature of -10 ℃ ~ + 40 ℃, relative humidity less than 80% of the standard conditions, the accuracy of this type of resistance box of ± 0.5%. Fourth, the use conditions use conditions: temperature of 0 ℃ ~ + 40 ℃, relative humidity less than 80%. 6, the main technical performance :( according to user requirements) 1 Accuracy AC, DC, 0.5 level maximum power ≥500W. 2 limit the amount of leakage current 2.1 100uA-400mA 2.2 Capacity: test capacity and pressure resistance value is set equal resistance. So that the output voltage maximum power, we use the full power resistor, so no need to calculate. 3kV5mA, 3kV10mA, 3kV20mA, 3kV50mA, 3kV100mA 4kV5mA, 4kV10mA, 4kV20mA, 4kV50mA, 4kV100mA 5kV10mA, 5kV12mA, 5kV20mA, 5kV40mA, 5kV50mA, 5kV100mA 6kV10mA, 6kV20mA, 6kV50mA, 6kV100mA, 10kV10mA, 10kV20mA, 10kV50mA 15kV10mA, the points above are available 15kV20mA Full load measurement. Available at half load measurement are: these points plus half of the rated voltage is half load measurement, in addition, can also be used half of the load box load measurement 3kV200mA, 4kV200mA, 5kV200mA, 15kV100mA Seven, use and care of 1 Use 1.1 breakdown current test for safety, set on the resistance box of metal ground terminal, before using the ground terminal and the ground should securely connected! ! ! The left side of the load box gray area is the leakage current measurement. Press withstand voltage tester test procedures wiring resistance, voltage tester output high voltage terminal first, then load box corresponding current measurement jack, then from the public side to the thickness of the lead ※ mark potentiometers, then connect the lead to the end of the potentiometer measuring device Red current terminal, from black current low-end low-end return pressure instrument. ※ symbol of gray to black gray part of the public side, the other terminals of the test side, the resistance value of the test is relatively gray terminal marked common terminal. In 5kV pressure meter, for example, the output voltage is set voltage meter 600V ~ 650V, high voltage to the load termination box corresponding jack, take a good line, after the check, open digital meter switch, the changeover switch in the desired range, turn on the power, slowly raised pressure tester output voltage until the voltage tester close to the alarm value, adjusting the thickness profile plus fine tune the potentiometer until the voltage meter alarm and cut off the output voltage, recorded at the moment Current, repeat the test N times the mean value, that is the point of breakdown current. (0.5mA The following section shall resistor in series over borrowing capacity, load box after the three-part series resistance of 3MΩ, three ※ mark resistance of the common terminal under the jurisdiction of independent, orange capacity of common terminal portion of the first rows of black and 3kV20mA and 3kV10mA side buttons constitute a loop, other portions of the end button orange capacity with orange region of the second row of black common form a loop) 0.5mA or less measured with a 100kΩ potentiometer;. 0.5mA ~ 2 mA with a 100kΩ potentiometer for coarse, 10kΩ potentiometer for fine tuning; 2mA ~ 20 mA with a 10kΩ potentiometer for coarse, 1kΩ potentiometer for fine tuning; 20mA ~ 50 mA with a 1kΩ potentiometer for coarse, 470Ω potentiometer for fine tuning; 50mA ~ 120 mA with 470Ω potentiometer for fine tuning, 120mA above do not take potentiometer. Capacity utilization portion of the resistance can be measured leakage current under high pressure. Measurement should ensure that there is no series circuit breaker phenomenon. Do not touch the metal part of the operator! Withstand voltage tester which may be removed after cable cut off the pressure!
