Chapter 14—Maintenance and upgrades PowerLogic™ PM5500 series user manual

Phasors can be used to troubleshoot incorrect connections on the meter’s voltage and current inputs. The phasors can reveal switched phase wiring or polarity errors.

NOTE: If two phasor lines overlap (i.e. if they have the same relative phase angle), only one phase label is visible as phasor diagram labels are overwritten dynamically on the display panel.

Maintenance log

The meter’s maintenance log can be accessed using the webpages. See “Diagnostics” on page 59.
