Figure 45: HV Waiting Screen
– Security Circuit Open
The HV Waiting Screen will display the status message INTERLOCK OPEN if the security circuit is not
closed on the test set. This status message will appear at the HV Waiting Screen if an open Security Circuit
is detected regardless of what operation mode the PM15-4A is set to (Normal or Guard). If this message is
seen, check the security circuit for loose connections or replace the SX1 plug onto the front panel to close the
security circuit. Press the red HV ON push button to activate the high voltage test. The Dielectric Absorption
Ratio Testing Screen will be displayed.
FIGURE 46: Dielectric Absorption Ratio Testing Screen
The Dielectric Absorption Ratio Testing Screen (Figure 46) will display real-time data on voltage, current and
resistance. After the test is complete, the test complete screen will come up (Figure 47) and the user may
print or save the results. Either printing or saving to the SD Card will give the operator resistance
measurements for every ten seconds in addition to the final Dielectric Absorption Ratio result. The PM15-4A
will discharge the test object upon test completion.
WARNING
: Depending on the size of load capacitance, dangerous voltages may be present at the end of the
lead for a few moments. Always ground any high voltage leads before removing leads from test object. The
use of appropriately rated discharge and grounding devices is recommended to ensure that the test object is
fully discharged and grounded before removing leads after testing is complete. A minimum discharge time
which is approximately 4 times that of the voltage application duration is recommended.
