Wiring method
The current loop should be connected with the thick wire in the test wire, and the voltage loop should be connected with the thin wire in the test wire. (This instrument is equipped with a set of 4 x 8m test leads)
1. The measurement wiring for a single resistor is shown in the figure below. RX is the measured resistance.
2. When the measuring resistance is greater than "2Ω", select the constant current to test, press the "Move" button to move the indicator arrow "↑" to the right, select "A", press the confirmation button, press the "Print" button to increase, press The "Move" key decreases. Use this formula I = 10/Ω to roughly estimate the current, select the appropriate current to increase the measurement accuracy, press the ENTER key to display the loop current, and then press the ENTER key to test. After the resistance value is displayed, printing and discharging operations can be performed.
Operation method
The DC resistance tester has five buttons: "reset", "print", "move", "discharge" and "determine".
Resistance measurement:
After turning on the instrument or pressing the reset button, the instrument enters the initial state (1). Press the "Move" key to move the "↑" cursor pointer back and forth to select the desired function, so that the "↑" key points to "Ω", press the "OK" key to enter the state of automatic resistance measurement (2), display the resistance value (3) . Press the "Print" button once to print the measurement results. After the test is completed, press the "Discharge" button and the instrument will automatically discharge
DC resistance tester considerations
1. When using the instrument, do not block the exhaust fan window to facilitate heat dissipation.
2. If an abnormal situation occurs during the measurement, please check the wiring is correct, press the reset button or shut down. If it cannot be returned to normal, please contact the factory and do not disassemble it yourself.
