1. 2 3 L Earth Ground Figure 2 4 1 Output Terminal Connection 2 5 Remote Sense Connection The remote sense function of the AC source monitors the voltage at the load instead at the output terminal of the AC source It ensures the delivery of accurate voltage as programmed at the load by automatically compensating the output voltage drop over the connecting cable Connect the sensing leads as shown in Figure 2 5 1 Because the sensing leads carry only a few milliamperes the wires for sensing are much lighter than the load leads The sensing leads are part of the feedback path of the AC source so they must be kept at a low resistance in order to maintain the best performance Connect the sensing leads carefully so that they will not be open circuited If the sensing leads are left unconnected or become open circuited during operation the AC source will disable the output The sensing leads must be a twisted pair to minimize the pickup of external noise The sensing leads need to be connected to the load as close as possible 2 5 Programmable AC Power Source 61705 User s Manual gt AC INPUT WES A Figure 2 5 1 Output amp Remote Sense Connection 2 6 The Procedures of Power on WARNING Before turning on the instrument all protective ea
