This procedure can be used to verify the warranted
characteristics of the AP034 Active Differential Probe.
The recommended calibration interval for the model AP034
Active Differential Probe is one year. The complete performance
verification procedure should be performed as the first step of
annual calibration. You can record test results on a photocopy of
the Test Record provided at the end of this section.
You can do the performance verification without removing the
instrument covers, exposing yourself to hazardous voltages.
Adjustment should only be attempted if a parameter measured in
the Performance Verification Procedure is outside of the
specified limits.
Adjustment should only be performed by qualified personnel.
TEST EQUIPMENT REQUIRED
Table 3 lists the test equipment and accessories (or their
equivalents) that are required to verify the performance of the
AP034 Active Differential Probe.
This procedure is designed 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.
