2.2. CONNECTING TO THE PRODUCT UNDER TEST
The PM1000+ will measure up to 600Vrms and 20Arms directly using the 4mm
terminals on the front panel. For measurements outside the range (low or high power)
see the section on Using Current and Voltage Transducers later in this manual.
To measure power, connect the PM1000+’s measuring terminals in parallel with the
supply voltage and in series with the load current.
Always use good quality safety cables as supplied and check that they
are not damaged before use.

The simplest and safest way to make a connection to the
product under test is to use a Voltech Break Out Box. This
provides a line socket for connection of the product and 4 x
4mm sockets for direct connection to the PM1000+
terminals as described above.
2.3. DEFAULT MEASUREMENTS
Switch on the supply to the load and the PM1000+ is now ready to make
measurements. Note that it is not necessary to switch the PM1000+ either off or on
when the load is being connected.
The default display shows 4 values. Each line clearly shows the measurement type
‘Vrms’, the measured value, ‘248.4’ and the measurement units, ‘V’. Normal
engineering notation is used to describe units, e.g. mV = milli-volts (10-3) and MV =
mega-watts (10+3).
To scroll through the measurements, use the 4 keys to the right of the display:
Jump Up Display the page above.
Up Move up through the measurement list.
Down Move down through the measurement list.

USING VOLTAGE AND CURRENT TRANSDUCERS
PM1000+ Power Analyzer User Manual © Voltech 2007 Page 3-1
3. USING VOLTAGE AND CURRENT TRANSDUCERS
3.1. INPUT OVERVIEW
Voltage
Voltages of up to 600V rms may be connected directly to the black and yellow 4mm
VHI and VLO safety sockets at the front of the PM1000+
Current
Currents of up to 20A rms may be connected directly to the black and yellow 4mm AHI
and ALO safety sockets at the front of the PM1000+
External Current Inputs
The external current inputs accept a voltage of up to 1V rms that is proportional to the
current being measured. This input allows a very wide range of external current
transducers to be connected, from low mA current shunts to MA current transformers.
For each type of transducer, the PM1000+ may be scaled to read the correct current.
See the INPUTS menu.
The choice of current transducer will depend on:
• The current being measured, including peaks and transients.
• The accuracy required.
• The bandwidth required: Unless the waveforms are purely sinusoidal, a bandwidth
in excess of the fundamental frequency will be required.
• Whether there is DC current present.
• Convenience of connection – E.g. using a clamp-on current transformer, with jaws
that open, for quick connection in a fixed wiring loom.
• The effect of the transducer on the circuit.

USING VOLTAGE AND CURRENT TRANSDUCERS
Page 3-2 © Voltech 2007 PM1000+ Power Analyzer User Manual
3.2. TO CONNECT A SIMPLE CURRENT TRANSFOMER
To use a conventional current transformer (CT) like the Voltech CL series (or any other
transducer with a current output), connect the normal AHI and ALO inputs of the
PM1000+ to the outputs of the current transformer. Follow the manufacturer’s
instructions for the safe use and installation of the transducer.
Normally the positive or HI output of the transducer will be marked with the point of an
arrow or a ‘+’ symbol. Connect this terminal to the AHI input of the PM1000+.
Scaling.
A current transformer produces an output current which is proportional to the load
current being measured. For example, the Voltech CL100 produces an output current
that is 1/100 of the current being measured.
To measure the correct currenton the PM1000+, use the scale function of the analyzer
to scale, or multiply, the CT output current.
For example, the CL100 is a 100:1 CT. When measuring 100A, its output is 1A. To
scale this on the PM1000+, a scale factor of 100 must be entered:
Press ’MENU’
Select "# ‘Inputs’ and press !
Select "# ‘Scaling’ and press !

USING VOLTAGE AND CURRENT TRANSDUCERS
PM1000+ Power Analyzer User Manual © Voltech 2007 Page 3-3
Use the delete key to clear the entry.
Type the new scale factor (100)
Press OK
Press ‘MENU’ to return to the measurement display.
The PM1000+ is now ready to make measurements using a CT.
3.3. TO CONNECT AN EXTERNAL RESISTIVE SHUNT:
Using resistive shunt is a straightforward method of extending the current measuring
range of the PM1000+. The shunt resistor is connected in series with the load and the
voltage across the shunt is directly proportional to current.
That voltage may be connected directly to the External Current Inputs of the PM1000+.
For example, a 1milli-ohm shunt is to be used to measure 200A rms.
1. Check the voltage that will be generated is suitable for the PM1000+
V = I x R (Ohm’s law)
Vshunt = I x Rshunt
Vshunt = 200 x 0.001 Ohms
Vshunt = 0.2V
This is well within the 1V rating of the PM1000+’s External Current Inputs
2. Connect the shunt in series with the load and to the EXT-HI and EXT-LO inputs
as shown.

USING VOLTAGE AND CURRENT TRANSDUCERS
Page 3-4 © Voltech 2007 PM1000+ Power Analyzer User Manual
REMOVE ANY CONNECTIONS TO THE NORMAL ALO TERMINAL!
EXT-LO and ALO are connected inside the PM1000+. To avoid errors
and a risk of electric shock, remove all connections to ALO.
3. Set up the PM1000+ to measure current from the EXT-HI and EXT-LO terminals.
Press ’MENU’
Select "# ‘Inputs’ and press !
Select "# ‘Shunts’ and press !
Select "# ‘External’ and press !
!!
!
Press ‘MENU’ to return to the measurement display.
4. Scale the measurement on the display.
The default scale is 1V = 100A.
The scale required for any external shunt is given by:
Scale = 1 / (100 x R) (where R is the resistance value of the shunt).
In this example where R = 0.001 Ohms
Scale = 1 / (100 x 0.001)
Scale = 1 / 0.1 = 10
To enter a scale factor for current:
Press ’MENU’
Select "# ‘Inputs’ and press !
Select "# ‘Scaling’ and press !
Select "# ‘Amps’ and press !
Use the delete key to clear the entry.
Type the new scale factor (e.g.10)
