<p>This device comprises a control unit 1 provided with means of connection to an electrical power supply 2 and containing a module which comprises an input 7 for the connection of an electrical monitor and an output connected to a cable 3 which ends in a connector 4 having several different pins 5a, 5b, 5c for connection to the terminals of the equipment to be monitored. Two selectors A, B select the pairs of terminals corresponding to the various equipment to be monitored; a switch 8 interposed between the selectors and the input allows the checking of pulsed voltages, and a unit 9 for checking the electromechanical devices comprises a generator 10 generating pulses of variable duration. The module comprises calibrated resistors provided with connections. <IMAGE></p> |
