The 3930 is a high voltage scanner that allows high voltage inputs to be output from any channel. A single unit is equipped with 8 channels (using single mode), and up to four units can be connected to give a total of 32 channels. In addition, the 3930 can be used in combination with the 3153 AUTOMATIC INSULATION/WITHSTANDING HiTESTER, displaying its capabilities as an unattended automatic testing device for multiple point insulation and AC/DC voltage endurance testing.
