1. INTRODUCTION
1.1 Inspection
Examine the shipping carton for any sign of damage. Inspect the
unit and any accessories for damage. If there is any damage then
consult your distributor immediately.
1.2 Description
The PSI4000 and PSI4300 are Non-Contact Phase Detector and
Phase Sequence Indicators with the following features:
uNon-contact connection clips to enhance user safety during
testing and also allow the testing of insulated conductors.
u IlluminatedLED’stoindicatethedetectionoflivephases.
u RotatingLED’sandbuzzertonestoindicateclockwiseor
anticlockwise phase sequence.
uAuto-off function after 5 minutes of non-detection.
uEnhanced brightness switch to make the indication brighter in
strong ambient light.
uMagnetic studs on rear casing to allow hands free operation.
The PSI4000 indicates correct phase sequence as a clockwise
rotation while the PSI4300 indicates correct phase sequence as an
anti-clockwise rotation.
1.3 Accessories (included)
u4 x 1.5V batteries LR6/AA
uSoft case
uInstructions
1.4 Battery Installation

2. PRODUCT SPECIFIC SAFETY INFORMATION
Measurement Category III (CAT III) is applicable to test and
measuring equipment connected to the distribution part of the
building’slow-voltageMAINSinstallation.
Measurement Category IV (CAT IV) is applicable to test and
measuringequipmentconnectedatthesourceofthebuilding’slow-
voltage MAINS installation.
2.1 Precautions
This product has been designed with your safety in mind, but please
pay attention to the following warnings and cautions before use.
Warning
Before use check the unit for cracks or any other damage. Make
sure the unit is free from dust, grease and moisture. Also check any
associated leads and accessories for damage. Do not use if damaged.
Warning
Do not use if the battery/fuse cover is not fitted.
Warning
Always test this unit on an appropriate proving device or known
voltagesourcebeforeandafterusingittodetermineifahazardous
voltage exists in a circuit to be tested. See 3.6.
Warning
When using the sensor clips, always keep your fingers behind the
finger guards.
Warning
IfoneormorephaseliveLED’sdonotilluminate,thisdoesnot
necessarily mean the phase or phases suspected of being open
2

or missing are actually dead. The phase to earth voltage of the
suspected phase could be < 75V, or two or all three sensor clips
could be sensing the same phase, thereby giving incorrect test
indications.
Caution
Avoid severe mechanical shock or vibration and extreme
temperature.
Caution
Remove the batteries when not in use for an extended period, to
avoid corrosion from leaking batteries.

3.2 Low Battery Indication
If the ON LED flashes when the unit is turned on, the batteries are
low and need to be replaced (see section 4.1 battery replacement).
3.3 Auto Power Off
If the PSI4000/PSI4300 is inactive for a period of approximately 5
minutes it will automatically power down.
3.4 Enhanced Brightness

3.5 Testing Considerations
The following considerations should be observed when using the
PSI4000 / PSI4300:
uIncorrect phase live test indications will be obtained if two or
three sensors are connected to the same phase. The L1, L2 and
L3LED’swillonlyilluminatesimultaneouslyifthesensorsare
connected to 3 separate phases, with phase to earth voltages ³75V.
uTouching the sensor clips during testing may give incorrect test
indications.
uIncorrect test indications may be obtained if the sensor clips
are attached near to a charged body or equipment generating
electromagnetic waves.
u Thespecifiedconductorsizefortestingisbetween2.4mmand
30mm diameter. Testing conductors outside of this range may
give incorrect test indications.
uTest indications may be influenced by other nearby cables with
a voltage magnitude that is double or greater than the voltage
magnitude of the cables being tested. The sensor clips should be
attached as far from such cables as possible.
uCorrect wiring status cannot be correctly identified when an earth
line is connected between phases via delta connection. Check the
connection specification of the 3 phase distribution system being
tested.
uCannot be used to test bus bars or metal shielded cables.
uDo not pull the sensor clip wires to remove the sensor clips from the
cables under test. This may break or damage the sensor clip wires.
3.6 Proving Check
Before and after use, prove the function of the PSI4000 / PSI4300
by performing steps 1 to 4 below:
1. Press the button to turn on the instrument. During the power
upsequence,alloftheLED’swillilluminatebriefly.
2.IfanyoftheLED’sdonotflashduringthepower-upsequence,
do not use the instrument.
5

3. After the power-up sequence, only the ON LED will stay
illuminated, all others will extinguish.
4. Prove the function of the L1, L2, L3 sensor clips by attaching
each in turn to a known live insulated conductor energised
at75VACorgreater,andconfirmthattheL1,L2,L3LED’s
illuminate. The tips of the Δ marks at the side of the clip jaws
should align with the centre of the conductor used for testing
(see figure 1).
Do not usetheunitiftheL1orL2orL3LED’sdonotilluminate
when performing step 4 above.
3.7 Testing a 3 Phase Distribution System
1. The three sensor clips are marked L1, L2, L3. These relate to
theL1,L2,L3LED’sontheinstrumentfacia.
2. To determine phase presence and phase sequence, attach
the three sensor clips of the PSI4000 / PSI4300 to the three
separate unshielded phase cables of the 3 phase electrical
distribution system to be tested, whilst referring to figure 1 and
observing the testing considerations of section 3.6.
3. Refer to table 2 of section 3.8 to determine onto which cable to
attach L1, L2 and L3 (see Note 2).
4. The presence of live phases and the phase sequence are
indicatedbytheLED’sandthebuzzersoundingassoonas
detection is complete. Refer to table 1 to determine the status of
each phase cable from the LED indications (see Note 3).

Note1:IfoneormorephaseliveLED’sdonotilluminate,
this does not necessarily mean the phase or phases suspected
of being open or missing are actually dead. The phase to earth
voltage of the suspected phase could be <75V, or two or all three
sensor clips could be sensing the same phase, thereby giving
incorrect test indications.
Note 2: The colours of the cables under test cannot be relied upon
to confirm the expected phases.

a phase marked as “L1” elsewhere in the fixed installation may
not be same phase as one marked as “L1” in the location being
tested. That must be verified by separate tests to confirm absence
of phase offset.
3.8 Wiring Colour Coding
In April 2004 the colour coding of UK wiring was harmonised with
the IEC wiring colour code. Table 2 shows the old UK colour code
and the new IEC colour code.
