Up to 15 Series EL Electronic Loads may be paralleled for additional current handling capability.
All units must have the same voltage rating. One load is designated as the Master, and the rest
are designated as slaves. Refer to PAR. 2.6.3 for connections.
A Master/Slave combination responds to an *IDN? query with the *IDN string from first the Mas-
ter and then the Slave(s).
