Equipment needed:
Series 3700A system switch/multimeter
Switching card
Flat-bladed screwdriver
WARNING
To prevent electric shock that could result in injury or death,
NEVER handle a switching card that has power applied to it.
Before installing or removing a switching card, make sure the
instrument is turned off and disconnected from line power. Even
when the instrument is powered off, hazardous voltages may be
present in signal cables attached to the switch cards. Always
disconnect all cables before removing or installing a switch
card.
If the switching card is already connected to a device under test
(DUT), make sure power is removed from all external circuitry.
NOTE
For inexperienced users, disconnect DUT and external circuitry
from switching cards. This allows you to exercise safe
close/open operations without the dangers associated with live
test circuits.
WARNING
Slot covers must be installed on unused slots to prevent
personal contact with high-voltage circuits.
To install a switching card in a Series 3700A instrument:
1. Turn the instrument power off.
2. Position the instrument so that you are facing the rear panel.
WARNING
As described in the International Electrotechnical Commission
(IEC) Standard IEC 664, the Series 3700A switch cards are
Installation Category I and must not be connected to mains.
