A voltmeter can be used to monitor DC input levels at
the AIN+ SENSE and AIN- SENSE pads. The reference
value seen by the part can be monitored at the VREF
SENSE pad. These pads have an isolation resistor to
prevent noise being injected by the voltmeter and are
useful for verification of DC measurements. When moni-
toring voltages through the SENSE pads, be sure to set
the voltmeter to high-impedance mode, as current
drawn through the isolation resistors can cause mea-
surement errors.
