LM-1312 Meter Adapter Recorder
A Versatile Meter Base "Plug-In"
Recorder.
The LM-1312 is a
Form 2S residential meter adapter recorder designed to simply plug into a meter
base to simultaneously record more than 30 energy parameters along with
harmonics, disturbance events, waveform capture, and flicker. The unit has
captive internal CT’s making installation and current measurement easy and can
be programmed to send real time notification when a measured condition exceeds a
user-programmed threshold. Data is kept in the meter in non-volatile
flash memory so that no data is ever lost and there is no battery maintenance
required to preserve recorded data.
Energy Measurements
The unit records more
than 30 energy parameters including Voltage, Current, kW, kVAR, kVA,
True and Displacement Power Factors, for each leg, total, and both
the single-cycle minimum and single-cycle maximum values for each
interval, as well as line Frequency. Time stamps are Internet
synchronized.
Power Quality
More and more residences have become vulnerable
to power quality problems because of home offices and so many
appliances using sensitive electronics. The LM-1312 records
voltage, current, swell and sag events, total harmonic distortion (THD%)
for both voltage and current and even measures and records
individual harmonics. Easy to use software generates charts and
reports in Excel®
eliminating software compatibility
problems. At a glance, sags or loose neutrals can be identified.
And you still have the Excel®
data to manipulate to do other
calculations if necessary.
