BASIC MEASUREMENT
49
F3 (Auto Zero)
key to enable Auto
Zero
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.
Frequency/Period Measurement
The GDM-9060/9061 can be used to measure the frequency or
period of an input signal.
