General operation 
This section provides information needed to use the 3762 10-channel 2 Form A High-Voltage Card 
with the Model 3706A system switch mainframe. Once the card is installed in the mainframe, refer to 
the Series 3700A System Switch/Multimeter Reference Manual for complete operating instructions.  
 
Safety hazards 
To prevent electrical shock that could cause injury or death, never make or break 
connections while the equipment is powered on. User supplied lethal voltages may be 
present on the PC board or the connections. Turn off the equipment from the front panel, 
disconnect the main power cord, and discharge stored energy in external circuitry before 
making or breaking cable connections. Putting the mainframe equipment into an output-off 
state does not guarantee that the outputs are powered off if a hardware or software fault 
occurs. Precautions must be taken to prevent a shock hazard by surrounding the test 
device and any unprotected leads (wiring) with double insulation for 1000 volts, Category I.
