Function Feature

This meter can real-time measure the multiple electric parameters of single-phase electric circuit, and it adopts the multiple-row LED display. One meter can fulfill the measuringtask of multiple common meters. For partial models, it can also be added with alarm contact output function according to the users' demand. It has the following features:  
★Buckle mounting way, easy and convenient installation.
★It can measure and display the voltage, current and frequency of the circuit at the same time.      
★True RMS measurement. 
★PT (or CT) multiplying power can be set freely. It is easy to match any specification of PT or CT.  
★It can be added with alarm contact output function additionally. The alarming upper and lower limit of voltage, current and frequency can be set freely. The 3-channel alarm can use the same relay to output, and then use LED lamp to indicate their alarming status. 
★It can respectively set the delay time of generating alarm and releasing alarm. 
★It has alarming lock function and alarming return difference setting function. 
★It has alarm electricity suppression function.
