Performance Verification
This procedure can be used to verify the warranted characteristics of the ZS4000
High Impedance Active Probe.
The recommended calibration interval for ZS series probes 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
This procedure has been developed to minimize the number of calibrated test
instruments required. Because the input and output connector types may vary on
different brands and models of test instruments, additional adaptors or cables
may be required.
