Usage Tips:[Wide demand]When using a clamp meter to measure current, it is necessary to clamp a wire to obtain accurate current values. If the power cord is directly clamped, the clamp meter cannot obtain the true circuit current value, because the internal wire currents will cancel out each other or stack currents in different directions. [Convenient measurement] The wire splitter separates the wires into a single or 10 times the current measurement window through its internal structure. In this way, you can accurately and conveniently measure the current value of a single wire inside a sheathed power cord without damaging the sheathed power cord. [Diverse functions] The splitter also adds a conversion switch. When the measured current is relatively small and only at or mA level, the switch can be placed in the OPEN position, the multimeter can be placed in the current range, and the probe can be inserted into the current test socket. The multimeter can accurately measure the small signal current without damaging the power cord. [Test power supply voltage]A voltage test socket can be used to monitor the power supply voltage through a multimeter. When measuring the power supply voltage, turn the transfer switch to the "Close" position. Insert the multimeter test probes into the two voltage test sockets of the splitter, and the measured voltage value can be obtained through the multimeter LCD. [Easy to operate] Insert the input plug of the splitter into the power socket, and then insert the load device plug that needs to be measured into the output socket of the splitter. Turn the transfer switch to the "Close" position. Turn on the power supply of the tested equipment and clamp the clamp of the clamp gauge into the branching device x 1 window to obtain the actual current value of the tested device.
