3. Usage
3.1 General
Keep fingers behind the finger guards shown below.
Check the correct function of the VIP
ESI both before and after use with a
true AC output proving unit such as
the Socket and See SP400.
The main body prod is
interchangeable to allow fitting of
either a straight or right-angle prod as
needed. Unscrew the collar, pull the
prod straight out from the main unit,
refit and tighten using normal finger
pressure. Check correct operation
afterwards.
Should the straight prod on the passive probe be damaged it can also be
changed. Unscrew the collar and then unscrew the prod from the probe body.
Be careful not to remove the Safety Resistor Cartridge from the probe body.
Screw on the replacement prod and refit the collar to finger tightness. Check
correct operation afterwards.
Please note: The passive probe straight prod and main unit prods are not
interchangeable.
3.2 Voltage Indication
To use as a voltage indicator, touch the prods onto the circuit to be measured.
The voltage between the two points of contact will be indicated immediately. If
the voltage is AC Mains, its impedance will be measured. This is shown by a
pulsing of the display and afterwards either HiZ or LoZ are indicated.

1.1 Equipment Markings
1.2 Operational Safety
The VIP ESI is designed to be used by skilled persons in accordance with safe
methods of work. If the VIP ESI is used in a manner not specified by Socket and See,
the protection provided by it may be impaired.
Inspect the product before using. If any damage is visible; such as cracks in the
casing, damage to any accessories, leads or probes, the unit should not be used.
Keep fingers behind the finger guards. Avoid touching a free prod while the other
prod is in contact with an electrical circuit. Avoid obscuring the indicator LED's
during use. This tester has been designed to be used with suitable PPE including
insulated gloves if required.
To maintain safety, check the correct operation of the VIP ESI, both before and after
use, with a true AC output proving unit such as the Socket and See SP400 or on a
know live source. Check that the voltage LED's are visible in the environment of use.
Caution - refer to this instruction manual
Safe for energized working ( up to 600V)
Product should be recycled as electronic waste
Conformity to EU standards
Measurement Category IV is applicable to test and measuring
circuits connected at the source of the building’s low-voltage MAINS
installation. This part of the installation is expected to have a
minimum of one level of over-current protective devices between
the transformer and connecting points of the measuring circuit.
Due to these high short-circuit currents (above 50kA) which can be
followed by a high energy level, measurements made within these
locations are extremely dangerous. Great precautions shall be made
to avoid any chance of a short circuit.
Examples of CAT IV are measurements on devices installed before
the main fuse or circuit breaker in the building installation.

2. Description
The VIP ESI is a 2 pole voltage indicator with enhanced safety features suited to
the electrical supply industry.
2.1 Indicator Parts
● Colour coded voltage bar graph displays the voltage between the prods.
● LoZ indicator: indicates the VIP ESI is connected to a low impedance circuit.
● HiZ indicator: indicates the VIP ESI is connected to a high impedance
circuit.
2.1.1 Bar Graph Details
50V 2 X White LED
110V 2 X Yellow
230V 2 X Blue LED
400V 2 X Red LED
The base display helps when
measuring in difficult locations. It is
always active.

3.3 Impedance Indication
The VIP ESI can be used to indicate impedance and therefore prospective
current. When AC Mains is detected, Impedance is measured automatically
the LED's will pulse to indicate an impedance measurement is being made.
Keep the prods still during the measurement and wait for the LED's to stop
pulsing.
For example, before reconnecting a supply:
● With the service cut-out fuse removed, connect
the VIP ESI to the fuse terminals (in place of the
fuse).
● The voltage and impedance should be measured.
If the green HiZ LED illuminates, the impedance is
high, (low prospective current) and it is safe to
insert the fuse.
● If the red LoZ LED illuminates, the impedance is
low, (high prospective current) and the installation
needs further investigation.
3.4 Automatic Ghost Voltage Suppression
Ghost Voltage suppression is automatic.
Firstly they are moderately suppressed by the operating current of the VIP ESI.
Secondly the Red and Green Impedance Measurement LED's will show whether
the voltage indicated has an impedance of more or less than 100Ω. Should the
Green LED illuminate this would indicate a high impedance voltage but even
high impedance voltages can be dangerous and further careful checks would
need to be made before proceeding.
Impedance is measured when the voltage is in the range 110-400V/40-60Hz
nominal. For voltages outside these limits neither the HiZ or the LoZ LED will light.
