INPUT and SENSE LO are not internally connected to the chassis and cannot be allowed to
float above chassis ground more than the values shown on the front panel.
Cable effects on dry-circuit ohms
Dry-circuit resistance applications include measurements where the voltage applied across the device
under test DUT is limited to 20 mV to 30 mV. The limited voltage is an important parameter when
measuring resistance of metal oxides on connectors, relays, or switch devices contacts during
environmental HALT and HASS testing.
The Model DMM7510 properly conditions the internal I
test
current and voltage clamping signals to
maintain less than 30 mV across the DUT.
