Modes of Operation:
Single Phase Current and Voltage
Set-up
For monitoring single-phase current with a voltage reference.
In this mode the logger will be powered from the mains, and
will be able to log for six weeks before it fills its memory at
the default five minute logging interval.
Instructions
•
Select the wiring configuration to be monitored
by pressing the function button.
•
Follow the on-screen prompt and plug in:
•
The mains cable.
•
The L1 coil.
•
Clip the coil around the correct conductor.
•
Wait for the logger to configure.
•
Read values from the screen, pressing the scroll
button to step through the current, voltage and
power readings.
Data Logging
•
Press and hold the Record button until the logger
confirms it is recording.

Modes of Operation:
Three Phase Current and Voltage
Set-up
For monitoring three-phase current with a voltage reference.
In this mode the logger will be powered from the mains, and
will be able to log for six weeks before it fills its memory at
the default five minute logging interval.
Before logging is started, the logger is in a set-up mode
where it automatically matches the voltage measurement
against the three current measurements.
Coil positioning is particularly important to allow this
automatic set-up to complete. See page 20 for examples,
and follow the prompts on the display.
Automatic set-up is complete once the prompts disappear;
recording can then be started.
Once recording, the position of the coils is no longer as
important and provided they remain around the conductors
they were configured to, the logger will measure correctly.
Instructions
•
Select the wiring configuration to be monitored
by pressing the function button.
•
Follow the on-screen prompt and plug in:
•
The mains cable.
•
Coils L1, L2 & L3.
