Performance Verification
HFP1500-OM-E Rev E
7–1
7 Performance Verification
This procedure can be used to verify the warranted characteristics of the HFP1500 High Fre-
quency Probe.
The recommended calibration interval for the model HFP1500 is one year. The complete perfor-
mance 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
• Offset Accuracy
• LF Attenuation Accuracy
TEST EQUIPMENT REQUIRED
Table 7-1 lists the test equipment and accessories (or their equivalents) that are required for per-
formance verification of the HFP1500 Probe.
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 connectors types may vary on different brands and models of test
instruments, additional adapters or cables may be required.
