Performance Verification
Performance Verification Overview
This procedure can be used to verify the warranted characteristics of the ZD Series High
Impedance Active Probe.
The recommended calibration interval for the models ZD Series is one year. The complete
performance verification procedure should be performed as the first step of annual
calibration. Test results can be recorded on a photocopy of the Test Record provided in
Appendix A at the end of the manual.
Performance verification can be completed without removing the probe covers or exposing
the user to hazardous voltages. Adjustment should only be attempted if a parameter
measured in the Performance Verification Procedure is outside the specification limits.
Note: Adjustment should only be performed by qualified personnel
This procedure tests the following specifications:
 Output Zero Voltage
 LF Attenuation Accuracy
Required Test Equipment
The following table lists the test equipment and accessories (or their equivalents) that are
required for performance verification of the ZD Series Probes.
This procedure has been developed to minimize the number of calibrated test instruments
required.
Only the parameters listed in boldface in the Minimum requirements column must be
calibrated to the accuracy indicated.
Because the input and output connector types may vary on different brands and models of
test instruments, additional adapters or cables may be required.
