In the software, obtain the SMTP server address from your provider for correct setting. If the SMTP server requires authentication enter the user name and password. -
Page 17: Transient
Transients of current - > EMK-01 quality analyzer detects two types of transients: absolute transient and differential transient. ● Absolute transients are detected according to override of defined voltage level. The trigger for detection of the absolute transients is defined by absolute threshold (percentage of Udin). -
Page 18: Events
Memory space for capturing of the particular transients is fixed on the maximum 8000 samples. Definition of number pre and post samples is limited by this maximum samples memory space. 8.8. Events The events captured by EMK-01 can be adjusted with the parameters given in the table below. Parameter Description... -
Page 19: Voltage Dip
Memory for capturing the samples of RMS curves is fixed on the maximum 4000 samples. Definition of number pre and post samples is limited by this maximum samples memory space. 8.8.1. Voltage Dip The dip threshold is a percentage of either Udin or the sliding voltage reference. The user should declare the reference voltage in use. -
