Connection precautions

WARNING
All connecting wires or leads must be connected to the card before it is installed in a
multimeter.
Connection information for the Model 2000-SCAN is intended for qualified
service personnel. Do not attempt to connect the DUT or external circuitry
to a scanner card unless qualified to do so.
To prevent electric shock that could result in serious injury or death, adhere
to the following safety precautions:
• Before making or breaking connections to the scanner card, make sure
the DMM power is turned off and power is removed from all external
circuitry.
• Do not connect signals that will exceed the maximum specifications of the
scanner card.
If both the front panel terminals and the scanner card terminals are
connected at the same time, the maximum signal ratings of the front panel
terminals are reduced to the maximum signal ratings of the scanner card.
As described in the International Electrotechnical Commission (IEC)
Standard IEC 664, scanner cards are Installation Category I and must not
be connected to mains.
