Rev Lx Ls Series II ENTRY DESCRIPTION SMC connector on the rear panel Transient List points data entry method Transient list points are numbered sequentially from 0 through 99 and executed in this order Each list point or list entry has 6 parameters as shown in the table above To enter list point data the right hand knob Frequency is used to increment or decrement the parameter value The left hand knob Voltage is used to increment or decrement the list point sequence number The sequence number can only be increased to the next available empty new list point To move to the next or previous parameter use the UP A or DOWN cursor keys The voltage and frequency slew parameters can be set to their maximum slew rates by turning the Frequency knob counter clock wise past 0 This will cause the slew parameter to wrap around to its maximum available value It is not necessary to use all list points only as many needed to accomplish the desired output sequence Setting Data Values Data values can be set for each point in a list If all data values in a specific list are going to be the same value e g the current limit parameter is set to the same value for the entire transient program only the first data value for that parameter has to be set Setting only the first data point will automatically repeat that value for all subsequent points in the transient list Setting Slew Rates Very of
