Voltage measurement connections
Even though the Series 3700A can measure up to 300 V, the maximum input to a switching
module may be less. Exceeding the voltage rating of a switching module may cause damage
and create a safety hazard.
Make sure the insulation and wire sizes used are appropriate for the voltages and current
being applied to the Series 3700A analog backplane connector. Use supplementary insulation
as needed. Exceeding the voltage rating of a wiring may cause damage and create a safety
hazard.
