Autozero provides the most
accurate measurements, but requires
additional time to perform the zero
measurement. With autozero
enabled (On), the GDM-9060/9061
internally measures the offset
following each measurement. It then
subtracts that measurement from
the preceding reading. This prevents
offset voltages present on the
GDM-9060/9061’s input circuitry
from affecting measurement
accuracy. With autozero disabled
(Off), the GDM-9060/9061
measures the offset once and
subtracts the offset from all
subsequent measurements.
When turning On the Auto Zero, the display
shows an icon indicating the Auto
Zero mode is currently being activated.
