1.2 Precautions
This product has been designed with your safety in mind, but
please pay attention to the following warnings and cautions before
use.
Warnings
In order to avoid the danger of electrical shock, it is important that
proper safety measures are taken when working with voltages
exceeding 30V AC rms, 42V AC peak or 60V DC.
Where applicable other safety measures such as use of protective
gloves, goggles etc. should be employed.
The voltage indicator must only be used by a skilled and competent
person who is familiar with the relevant regulations, the safety risks
involved and the consequent normal safe working practices, and is
capable of interpreting the results under the conditions and for the
purposes for which it has been constructed.
Before each use the unit should be examined for damage, cracks,
cuts or scratches. If there is any doubt the voltage indicator should
not be used.
Make sure the unit is dry, clean and free from dust, grease and
moisture while in use to avoid the danger from electric shock due
to surface leakage.
Before and after each use, the voltage indicator must be proven
using a suitable proving device or a known good voltage source.
Do not use the voltage indicator if any expected indication LED’s
fail to illuminate correctly during proving.

3
Testing for a voltage that exceeds the specified limits of the voltage
indicator may damage the unit and expose the operator to a shock
hazard. Always check the voltage indicator’s specified limits before
use.
The voltage indicator must only be used on CAT IV, CAT III and
CAT II installations up to 600V to earth, and within the operating
temperature and humidity range specified.
Do not use the voltage indicator if the battery casing is not fitted.
Always keep your fingers behind the finger guard.
The voltage indicator will not detect DC voltage.
Do not use the voltage indicator during rain or precipitation.
The voltage indicator must not be dismantled or modified in any
way by unauthorized persons. The safety of the voltage indicator
cannot be guaranteed under such circumstances and must not be
used.
Cautions
Avoid severe mechanical shock or vibration and extreme
temperature.
To avoid possible corrosion from a leaking battery, remove the
battery if discharged, or when the unit is not in use for an extended
period.

2. INTRODUCTION
2.1 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.
2.2 Description
The TEK100 is a non-contact voltage indicator suitable for detecting
the presence of AC voltage in the range of 100V to 600V.
The TEK100/YE and TEK101 are designed to be less sensitive, and
detect the presence of AC voltage in the range of 180V to 600V.
The TEK101 has an extended probe tip for access to confined
spaces.
A self test circuit checks the functionality and battery of the voltage
indicator.
2.3 Battery Installation
Refer to Section 4.1 (Battery Replacement) for the battery
installation instructions for the TEK100, TEK100YE and TEK101.

3. OPERATION
3.1 Self Test
The self test checks the functionality and battery, a proving check
should always be performed prior to use.
Set the voltage indicator OFF/PROVE/VAC switch to PROVE and
check for the following:
The LED is continuously illuminated;
The
V
~LED is flashing;
There is an audible tone.
Set the OFF/PROVE/VAC switch to VAC and check that only the
LED is still continuously illuminated and the audible tone has
ceased.
Do not use the voltage indicator if either LED fails to illuminate or
the buzzer fails to sound.
If both LED’s and the buzzer do not function, replace the battery
(see section 4.1 Battery Replacement) and retest the unit.
3.2 Proving Check
Before and after use, verify the voltage indicator is functioning
correctly on a known good voltage source.
Do not use the voltage indicator if either of the LED’s fails to
illuminate or the buzzer fails to sound during proving.
Warning
If the voltage source exceeds the specified limits of the voltage
indicator the unit may be damaged and the operator exposed
to a shock hazard. Always check the voltage magnitude of the
voltage source before proceeding with a proving check.

3.3 Testing for the Presence of Voltage
Warning
Non-contact voltage indicators are not suitable to determine
if a circuit is not hazardous live. A double pole voltage test
should always be used for that purpose.
Grip the voltage indicator fully and firmly around the hand grip
to obtain optimum and consistent sensitivity. A loose grip during
testing may reduce the unit’s sensitivity.
Set the OFF/PROVE/VAC switch to VAC.
Taking all necessary safety precautions and referring to section
3.4, apply the voltage indicator probe tip to the cable or area you
wish to test for voltage.
When an AC voltage is detected the V
~LED will flash and the
buzzer will sound.
Switch the tester off when not in use to conserve battery power.
3.4 Voltage Testing Considerations
From some directions the neutral and earth conductors in cables
will shield the live, so it is important that a cable is probed from all
directions.
When testing for the presence of voltage in multi-core cables
always run the probe tip of the voltage indicator along a short
length of cable so as to overcome the natural twist in conductors.
Be aware that if the presence of AC voltage is not indicated,
voltage could still be present. The unit indicates active voltages

7
in the presence of electrostatic fields. If the field strength is low
the unit may not indicate. This could be due to factors such as:
Low mains voltage (<100V AC rms, <180V for the TEK100/YE
and TEK101)
Shielded wire/cables
Thickness and types of insulation
Distance from the voltage source
Low battery
If testing at locations with high background noise levels, always
determine whether the buzzer is perceptible before relying solely
on the buzzer indication.

4. MAINTENANCE
4.1 Battery Replacement
To avoid shock or injury, remove the voltage indicator from
the vicinity of any external circuits before proceeding.
To gain access to the battery compartment, undo the screw
securing the battery compartment cover and lift off the cover.
Fit a new 9V, PP3 alkaline battery (IEC 6LR61, NEDA 1604A).
Replace the battery cover and the screw.
4.2 Cleaning
To reduce the risk of surface leakage, this instrument must
be kept in a clean condition.
Prior to cleaning, remove the voltage indicator from the
vicinity of any external circuits before proceeding.
If contamination is found, clean with a damp soft cloth and if
necessary a mild detergent or alcohol. Do not use abrasives,
abrasive solvents, or detergents which can cause damage to the
unit. If a mild detergent is used, the unit should subsequently
be thoroughly cleaned with a water dampened soft cloth. After
cleaning, dry and allow to remain in a dry environment for 2 hours
before use.
4.3 Repair & Service
There are no user serviceable parts in this unit other than those
that may be described in section 4. Return to Martindale Electric if
9
faulty. Our service department will quote promptly to repair any fault
that occurs outside the guarantee period.
Before the unit is returned, please ensure that you have checked the
unit and battery.
4.4 Storage Conditions
The instrument should be kept in warm dry conditions away from
direct sources of heat or sunlight, and in such a manner as to
preserve the working life of the unit. It is strongly advised that the
unit is not kept in a tool box where other tools may damage it.
