Abstract:
An electrical run test instrument, comprising:an output connection to a device under test (DUT); two input terminals, including: (a) a high voltage input terminal arranged to receive a high voltage from at least one separate external safety compliance test instrument; and (b) an AC line voltage input terminal arranged to receive an AC line voltage; run test circuitry for receiving and processing run test measurements when the DUT is supplied with said AC line voltage; and a high voltage switching matrix arranged to selectively connect said AC line voltage input terminal and said high voltage terminal to said output connection, wherein: (a) when said high voltage input terminal is connected by said switching matrix to said output connection, the high voltage from said at least one separate external safety compliance test instrument is supplied to said DUT to perform safety compliance tests, and (b) when said AC line voltage input terminal is connected by said switching matrix to said output connection, (i) the AC line voltage is supplied to said DUT to perform said run tests, and (ii) said run test measurements are supplied to said run test circuitry by said switching matrix.
