SEM-XXD Digital Multimeter, Contains 3 C.T, Three Phase Volt(L-L),(L-N), Ampere,Frequency, Phase Sequence Display (Color : 250D(10-250A))

RelaysGeneralSEM-60D/100D/250D Multimeter are designed to display 3 phase current, voltage and frequency.Usage and Working PrincipleMake the connections according to the diagram. Connect the current before electric charges to be connected to the system. SEM-60DUse the 3 pcs CT-60(1-63 A) current provided with the device. Connect the current lead wires to k-1terminals of the device. The device automatically displays the current value without any setting. So, don't use current of different brands and models. Wher the device is energized, it shows the phase-neutral, phase-phase voltages, frequency, phase sequence and current values on the displays SEM-100DUse the 3 pcs CT-120(10-100 A) current provided with the device. Connect the current lead wires to k-1terminals of the device. The device automatically displays the current value without any setting. So, don't use current of different brands and models. Wher the device is energized, it shows the phase-neutral, phase-phase voltages, frequency, phase sequence and current values on the displays.SEM-250DUse the 3 pcs CT-300(10-250 A) current provided with the device. Connect the current lead wires to k-1terminals of the device. The device automatically displays the current value without any setting. So, don't use current of different brands and models. Wher the device is energized, it shows the phase-neutral, phase-phase voltages, frequency, phase sequence and current values on the displaysYou can see the frequency between phase and phase, phase and neutral at the first display group. When the voltage values is shown (V) led gets on. While pressing the up button ,phase-phase range can be seen.When the phase-phase values is shown you can see the leds on phase phase. While pressing theup buttons you can see the frequency value and Hz led gets on.Phase Sequence: If the phase sequence is reverse you can see the (X) led gets on which take place in the 1
