WARNING: Failure to follow the instructions may result in personal injury or damage to the
instrument.
PC Specification:
The SPCPro has a large memory capacity and also utilises Bluetooth as its communication and
data transfer protocol. This requires a PC of the following minimum specification to make best
use of the product’s capabilities.
Windows: Vista or XP Pro
Processor: Pentium 4 or Centrino mobile 2.0 GHz+
RAM: 256MB+
Display: 32 bit colour 1024 x 768 minimum
USB:
A lower spec PC may provide satisfactory performance, but the graphing capability, particularly
with larger surveys will be slower. Download speed is dependant on the USB port spec.

The SPCProand its dedicated PC software package ‘PowerPackPro’ combine
new technology and years of experience into an unbeatable low-cost package.
It is the latest development of the well-proven “3 currents, 1 voltage” design,
which allows accurate 3 phase power and energy measurements to be made
safely. The unit uses 3 off AmpflexTM flex type CTs (current transformers) for
current measurement, and a standard wall socket plug for voltage
measurement and power supply. Set up and download of the SPCPro is via a
USB connection to any PC running Windows XP or later software, and all
survey data and user settings are securely saved in non-volatile ‘flash’
memory.
The instrument uses a sophisticated auto-ranging measurement technique
which ensures that excellent accuracy is maintained from 1 amp to 2000 amps
without the need for any user-setting of range, or swapping of CTs. It has
been developed with ease-of-use as a No 1 priority and is therefore simple to
set up, connect and download, assuring even non-technical or inexperienced
users of correct results from day one.
The SPCPro is a professional-grade instrument for the measurement
and logging of three-phase and single phase electrical loads. It is able
to measure the following parameters:
Voltage amplitude x 1
Current amplitude x 3
Current phase angle* x 3
*Referenced to the measured voltage
From the above data, the following parameters are presented via the
instrument’s dedicated software package ‘PowerPackPro’.
INTRODUCTION
DESCRIPTION
Voltage (1 phase)
Current (3 phases)
Power Factor (3 phase average)
kW (active power (3 phase total)
kWh (active energy) (3 phase total)
The unit is fully self-contained and is supplied with a set of permanently
connected AmpflexTM flex-type CTs, plus voltage connection and PC
connection (USB) cables. The rechargeable battery provides on-board
power for surveys of up to 2 weeks duration where mains power is not
available.
The SPCPro uses a rechargeable internal battery to provide power for
surveys where a mains voltage is not available, and to provide back-up
power in the event of a mains failure during a normal survey. The
battery will charge whenever the unit is connected to a mains supply,
but a faster charge rate is achieved with the unit switched off. It is
strongly recommended that the battery is charged for a minimum of 12
hours prior to commencing a survey. Battery condition may be checked
via the software interface.
The unit requires little or no set up prior to commencing a survey, as
the only user-definable variable is the survey storage period/survey
length. This is set via the PC software. Once the storage rate has been
set, it is not necessary to repeat the procedure for future surveys unless
the rate is changed.
Note: If the instrument does not power up as expected, or does not
communicate correctly with the PC, a GENERAL RESET may be carried
out by pressing and holding both buttons simultaneously for 3 seconds.
The unit will reboot when the buttons are released.
SET UP & USE
Logging Indicator Multi-function Display
Power Indicator
Sleep Button Reset/Start Button USB Connection Socket
Display:
On start-up the display shows the logger status, followed by
measurement values for current and voltage.
Sleep Button:
THE FRONT PANEL
The ‘sleep’ button will switch the unit into standby mode. If the unit is
recording when the button is pressed, the display will warn that the
survey will terminate, and provide a 5 second countdown to avoid
unintended operation.
Reset/Start Button:
Pressing the ‘Reset/Start’ button initiates a 5 second countdown prior
to commencing logging.
Note: any data stored in logger memory is erased when
as new survey is started.
Power Indicators:
The blue ‘power’ indicator will illuminate when the unit is connected to
a valid supply voltage (175-300 VAC). When the led is ‘off’ the SPCPro
is operating from battery power.
Logging Indication:
The red ‘logging’ indicator provides a short flash every few seconds
whilst a survey is taking place.
USB Connection Socket:
The SPCPro is connected to a PC from this port using a standard USB ‘A
to B’ interface cable (supplied).
SETTING UP
Refer to the ‘PowerPackPro’ section of this manual for detailed
instructions on setting up the SPCPro prior to commencing operation.
CONNECTING UP
Voltage Connection:
The SPCPro is supplied with its flex CTs already connected, which
means the only physical connection to be made to the instrument is the
mains supply. This should be carried out via the supplied lead to a
230VAC wall socket. If a wall socket of the correct type is not available
refer to Elcomponent for availability of alternative connection cables.
Warning: The connected voltage must not exceed 300VAC.
Exceeding the voltage will damage the instrument and
could be hazardous.
Current Connection:
The SPCPro is suitable for use on both single phase and three phase
supplies. Current measurement connections are made by clipping the
flex-type CTs around the conductors as shown in the following diagrams
and pictures.
NOTE: It is important to be able to identify cables
correctly when carrying out electrical surveys. Failure to do
so may compromise the accuracy of results obtained.
Please refer to Appendix 2 for information on UK wiring
connections. If you are working outside the UK, additional
information may be required.

NOTE: It is essential to orientate the CTs with the arrow
pointing towards the load as shown.
NOTE: It is essential that the phase cables are correctly
identified when connecting the flex CTs. (See Appendix 2
for more information on phase identification).
NOTE: It is not necessary to have a wall socket voltage
connection available to carry out a survey. The SPCPro will
continue to operate on battery power for up to two weeks
on a fully charged battery. In this case, power and energy
values are based on user-defined references.
STARTING A SURVEY
Once the unit is connected, logging is initiated by pressing and holding
the ‘Start/Reset’ button for 5 seconds. Note that the display will ‘count
down’ to the survey start. Logging is confirmed by the red ‘logging’ led
flashing every few seconds.
ENDING A SURVEY
A survey may be ended manually by pressing & holding the ‘sleep’
button.
Surveys will end automatically if the programmed survey duration is
reached, or if the power is removed and the battery life exceeded.
In all cases the recorded data will be securely saved for download.
DOWNLOADING A SURVEY
Please refer to sub-heading “Connecting the SPC Pro”in the following
section for details on data download and presentation.
