Safety precautions for connections
WARNING
Connection information for switching cards is intended for qualified service personnel. Do not
attempt to connect DUT or external circuitry to a switching card unless qualified to do so.
To prevent electric shock that could result in serious injury or death, comply with these safety
precautions:
Before making or breaking any connections to the switching card, make sure the Series 3700A
is turned off and power is removed from all external circuitry.
Do not connect signals that will exceed the maximum specifications of any installed switching
card.
If both the rear analog backplane connector of the Series 3700A and the switching card
terminals are connected at the same time, the test lead insulation must be rated to the highest
voltage that is connected. For example, if 300V is connected to the analog backplane
connector, the test lead insulation for the switching card must also be rated for 300V.
Dangerous arcs of an explosive nature in a high-energy circuit can cause severe personal
injury or death if contacted. If the multimeter is connected to a high-energy circuit when set to
a current range, low resistance range, or any other low-impedance range, the circuit is
virtually shorted.
