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;
V ~
The
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
3
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
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
