INTEGRATOR

The PM3300 provides comprehensive integration capability for determining energy
consumption, maximum demand, or averaged values over a time period.

The following functions and their fundamentals are available as integrated
measurements.

WATT-HOURS, VA-HOURS, VAr-HOURS, AMPERE-HOURS, AVERAGE POWER FACTOR

The integrator can be programmed from the menu to operate in response to

i). Manual control. Integration started and stopped from front
panel pushbuttons.

ii). External control. Integration under remote control via rear panel
connector.

iii). Time control. Integration controlled by the real time clock.
User can set Start and Stop time/date, reset
interval and time bands.

Automatic data dumps are made to the printer in all cases.

INTEG INTEGRATOR
- hr
This key sets the displayed value indicated by the cursor to change to
the corresponding integrated value (eg Watts to Watt-hours).

FUND FUNDAMENTAL

This key displays the fundamental integrated value alongside the rms
integrated value.

The integrator operates independently of other measurement functions, allowing the
user to make normal measurements alongside integration measurements.

DATALOG

The PM3300 can record and analyze short term events, from a few milliseconds up
to a minute. The waveforms are recorded , and power parameters previously set up
on the printer menu, are printed after analysis.

Data logging can be triggered manually, or triggered externally using the integrator
input on rear panel. The waveforms themselves are available on the ‘analog’ outputs.
For example, the short-circuit current, power and power factor due to an earth fault
can be easily measured and analyzed by using this function.

Datalog measurements are programmed from the main menu.
