Auto Zero Operation
The scope software includes a feature to null the probe’s residual offset voltage.
The probe should be disconnected from any signal and the Auto Zero button on
the probe menu pressed. This will measure any residual offset in the probe and
remove it from the measurement.
Connecting the Probe to the Test Circuit
To maintain the high performance capability of the probe in measurement
applications, care must be exercised in connecting the probe to the test circuit.
Increasing the parasitic capacitance or inductance in the input paths may
introduce a “ring” or slow the rise time of fast signals. Input leads which form a
large loop area will pick up any radiated electromagnetic field which passes
through the loop and may induce noise into the probe input.
Using one of the available accessories makes the ZD200 probe with its small
profile and low mass head ideally suited for applications in dense circuitry.
Care and Maintenance
Cleaning
The exterior of the probe and cable should be cleaned, using a soft cloth
moistened with water. The use of abrasive agents, strong detergents, or other
solvents may damage the probe. Always ensure that the input leads are free of
debris.
The probe case is not sealed and should never be immersed in any fluid.
