The advantage of Electrocorder products over most
others is that our Data Loggers constantly sample
information (recording the Minimum, Maximum and
Average reading) over the set period. Many other
products only take ‘snap shots’ of what is going on
and can miss 99.9% of the data that is critical to your
Electrocorder Model: PV-3
The PV-3 is specifically designed to accurately monitor one DC
voltage channel, 1V to 300Vdc and one DC current channel -10A
to +10A, -100A to +100A. This allows you to monitor charger
performance and PV (photovoltaic) cell output, as well as many
other applications like DC motors.
peaks and troughs which are one cycle or longer.
Setting up the Electrocorder PV-3 is easy, suitable for non-technical
staff. Using the supplied (free) Windows software, Electrosoft, input
the location details for the logging and choose the logging period.
Electrosoft will print the necessary dispatch/ return documentation
including user instructions. All data is included in a database
of dispatches and returns, allowing you to track the location of
multiple loggers.
The recorded data is uploaded to a PC via the supplied USB cable.
Using Electrosoft, the recorded current levels with dates and times
can be viewed in both tabular and graphical form, exported to a
spreadsheet or saved to file. Graphs can be printed showing the
recorded levels and the allowable tolerance bands. These results
may then be discussed with the customer.
Why is the Electrocorder better than other similarly priced
competitors? The Electrocorder range uses a constant sampling
technique, unlike the single reading of competitors. When the
loggers start to record, they sample every channel 16 times per
cycle, a cycle is 16ms at 60Hz. At the end of each averaging period,
3 quantities are saved for each channel: the True RMS average, the
Max, which is the highest cycle value during the period and the
Min, the lowest cycle value. This means that it will record all the
The voltage and current levels are stored with dates and times. With
the backup battery, the Electrocorder can continue to record for up
to a year.
On the logger, recording is signified by a flashing green light.
A red light advises users that the unit has completed recording.
The PV-3 has a current range ±10A & ±100A.
