Measurement Configuration

PQ Logger Mode
PQ Logger mode provides the ability to log measurements over an extended period of time to
find intermittent issues or trend data to discover the overall performance of the electrical
system. PQ Logger mode includes all the PQ Meter Mode functions as well as additional
measurements to customize the average period for each of the stored measurements and the
collection period.
In PQ Logger mode, the Analyzer guides you through the steps to collect measurements that
describe the health of the electrical system during the measurement period. The first screen
shown is the Measurement Settings screen that includes extra items compared to the
PQ Meter setup.
The extra items are:
Power Quality Standard
Mains signaling voltage
AUX (analog inputs)
See PQ Meter Mode for descriptions of other settings.
PQ Logger Measurement Settings
The Measurement Settings screen enables the evaluation method for the captured
measurements.
Power Quality Standard
During the logging session, the measured values are captured and evaluated according to the

PQ Health screen as an overview of all measurements. See Measurement Data Review for
more information.
