First Measurements - Fluke 1730/BASIC User Manual

The Logger is now ready for the first measurements or
energy study.
Note
Be aware that for power measurements in 3-phase
systems:
Total Active Power (W) is the sum of the
individual phases
Total Apparent Power (VA) also includes the
neutral current that can result in a very
different result than the sum of the three
phases. This is especially noticeable when a
signal is connected to all three phases (for
example, a calibrator) the total value is
approximately 41% higher than the sum of
each phase.
Total Fundamental Power (W) only delivers
the sum of each phase when the phase
rotation is clockwise. It is zero when the phase
rotation is counter-clockwise.
For more information, see the white paper,
Measurement Theory Formulas, at
for a list of formulas.

First Measurements

At the energy study site, look at the information in the
panel and the rating plates on the machines. Based on
knowledge of the electrical supply in the facility, determine
the configuration.

To start measurements:
1. Connect the Logger to mains power.
Note
See page 15 if you want to power the Logger from
the measurement line.
The Logger starts and shows the Meter screen with
Volts, Amps and Hz readings.
2. Push Change Configuration. Confirm the study type
and the wiring configuration is correct. For most
applications the current range is set to Auto and the
voltage and current ranges are 1:1.
3. Push Configuration Diagram for guidance on the
voltage test lead and current probe connections.
4. Plug the voltage test leads into the Logger.
5. Use the Thin-Flexi current probes and plug the phase
A current probe into the phase A/L1 input jack on the
logger, the phase B/L2 current probe into the phase
B/L2 input jack on the logger, and the phase C/L3
current probe into the phase C/L3 input jack on the
logger.
6. Apply the iFlex Probes to the wires in the electrical
panel. Make sure the arrow on the probe points to the
load.
7. Connect the voltage test leads to neutral, phase A/L1,
phase B/L2, and phase C/L3.
