General description
FAZER 767 BASIC is intended for performing basic tests of 220V/380V electric installations, car installations
and other electric installations. With Fazer 767 you can also check the operations of electrical devices. As for
electronics, Fazer 767 allows, among other things, to detect 0/1 and check resistors, capacitors, diodes and
transistors for malfunction. The device does not have a power off switch. Fazer consumes power only during
the measurement. Precise, carefully developed Fazer's electronic circuitry ensures very low power
consumption. Alkaline batteries LR44 allow to perform more than 10000 measurements. Fazer cannot be
dismantled.

Basic modes of operations
Fazer 767 operates in one of the four basic modes: PHASE, CONT, VOLT. In the PHASE mode, Fazer 767
uses the operator's body as electric earth, and in the CONT and VOLT modes Fazer 767 uses the skin's
conduction. Thus, good contact between a hand and the contact is advisable. In order to improve this contact
you can slightly moisten your fingers before performing a measurement in the CONT and VOLT modes.
9
"PHASE" Mode
do not touch the contacts, do not touch any contacts
ALTERNATING VOLTAGE PHASE INDICATOR Grab the Fazer's
body. Do not touch the metal contacts.. Voltage "PHASE" will be
indicated by a red LED (visual signal) Note: Sometimes Fazer may
indicate voltage in case of a non-live wire but one that is located near
another live wire.
10
"CONT" Mode
touch the "CONT" contact
CONDUCTION CONTINUITY INDICATOR. FAZER 767 differentiates
between non-conduction and conduction at approx 1 MΩ. Press the
CONT contact. The measurement pin and the operator's second hand
should touch measurement points of a tested object. Conduction is
signalled by the red LED going ON. Note: In the CONT mode the
measurement should be performed with the power supply switched
OFF, since induced voltage makes correct indication impossible.
11
"VOLT" Mode
touch the "VOLT" contact
"-" DIRECT VOLTAGE INDICATOR. Fazer detects voltage and
polarization of direct voltage with the value bigger than 2.5 V. Press the
VOLT contact. The measurement pin indicates positive voltage in
relation to the VOLT contact. Therefore, the operator's second hand
should be connected to the voltage negative pole. For instance, the
battery's or power supply plug's "-" contact, or the body of a device,
where one can find negative ground. If there is "+" voltage on the pin,
Fazer will react by lighting up the visual indicator.
12
Exchanging the batteries
Power supply: two alkaline batteries LR44, AS44 or replacements.
Batteries are located under a cover on the Fazer's bottom side. Pull the
battery cover aside gently. Slide the cover towards the measurement
pin. Replace the batteries. Observe the correct "+" and "-" polarization.
Follow the marks inside the battery chamber.
Battery maintenance
If the device fails to signal the measurement results the batteries' contacts may be dirty. Take the batteries
out, clean them with a dry cloth or spirit and put them back in. Sometimes, it's enough just to move the
batteries around their axis inside the device.
13
The most frequent applications
220/380V grid, electric installations, devices, electronics, direct current, cars
14
Detection of PHASE in the PHASE mode
Phase and zero detection is a basic test, equivalent to operations of the so called neon tester, the only
difference being that in case of Fazer there is no need to touch a metal contact. Fazer should be held by its
body. Touch a tested area with the pin. Fazer will react when it detects 220V voltage phase. Fazer will not
react in case of "zero". One should note the voltage induced on wires connected neither to "zero" nor "phase"
but running alongside live wires.

15
Breaks/shortings detection. Testing cables. The CONT mode
This application allows to control cables, fuses, light bulbs, etc. for current conduction. Touch one of the ends
of a tested object with the measurement pin and grab the other end of the object with you hand. If there is a
break in conduction FAZER will not react. A long cable ruptured inside its insulation - drive a metal pin inside
the cable at a certain distance from one its ends and check for conduction. By moving the pin you can find the
rupture location.
16
Determining the sequence of wires in a group of conductors - the CONT mode
This application allows to identify wires in large groups of conductors. Example: determining of the sequence
of wires is necessary e.g. when we have two cable boxes (A and B) with several wires of repeated colours
coming out of them.
- take a wire with unique colour in box A and B as the point of reference;
- in the box A, attach any wire to the wire of reference and try to detect it in the box B with the CONT test, and
then assign a sequential number to it (here, 2); - repeat it with remaining wires.
17
Verification of earthing - the PHASE mode
With this application you can roughly determine the quality of earthing of home devices connected to 220 V
grid. If a metal housing of a washing machine, a refrigerator, etc. is properly earthed, then FAZER will not
react in the PHASE mode. If FAZER reacts it means that the device's earth may not be enough, which may
lead to electric shock. FAZER's positive reaction will not always indicate danger (induced fields). However,
no reaction confirms correct earthing.
18
Working/Malfunction test. Searching for a rupture. The CONT mode.
With this application you can find a damage location in electric devices. Grab one of the pins of the power
cable's plug with one hand and touch the plug's other pin with the Fazer's measurement pin in order to check
for the continuity of conduction. You can locate a break inside the device by successively checking assembly
points with the Fazer's measurement pin outwards. Note: there must not be 220V voltage nearby since it will
disrupt the test.
19
0/1 detection in digital circuits in the VOLT mode
When operating in the VOLT mode, Fazer has the ability to find "0" or "1" in digital circuits. The Fazer's
activation threshold in the VOLT mode is approx. 1.5 V. Touch the assembly board (power supply zero) with
your second hand. Fazer's measurement pin will detect gate bias (0/1).
20
DC voltage detection - identification of "+" and "-" in the VOLT mode
This application allows to detect direct voltage levels from 2.5 V to 60 V. Grab the power supply's "-" of a
tested device with one hand. Using Fazer's measurement pin you can search for places with positive direct
voltage. Pole identification is done by changing the electrodes grabbed with the hand (or places on the
device). General rule: Fazer will react if there is positive voltage (U>2.5V) on the measurement pint as
compared with the operator's second hand holding the power supply's "-".
21
Detection of +12V/ground in cars in the VOLT mode
Grab a non-painted element of the car's ground (negative ground) with your hand. In the VOLT mode Fazer
will indicate points with +12V voltage. Note: with high level of air humidity you do not need to touch the car's
body.

22
Testing commutator motors in the CONT mode
Using the CONT mode you can check the continuity of individual windings in a motor. Touch ends of a single
circuit with the measurement pin and the operator's second hand, equipped with a sharp-ended pin. If the
motor's winding is in good order, Fazer will react
24
Testing of electronic components in the CONT mode
Diodes and transistors: With Fazer 777 you can check the diode connection. For example an npn transistor.
Grab the transistor's base with you fingers. Put Fazer's measurement pin to the transistor's collector and then
to its emitter. Fazer will react.
Resistors: You can check the continuity of conduction.
Capacitors: Grab one of the capacitor's terminals with one hand and touch the other terminal with the
measurement pin. Fazer will charge the capacitor, which will be manifested by a short flash. Changing the
terminals will again cause a short flash.
25
Telephone applications in the CONT and VOLT modes (touch CONT or VOLT)
All applications of the CONT and VOLT modes in 220V/380V electric installations and devices have their
equivalents in telephone installations and devices. With the CONT mode it is easy to check the continuity of
conduction in case of telephone set's elements (e.g. bells) and cables. Identification of wires in cable boxes
becomes just as easy. The VOLT mode allows, among other things, to quickly determine the line's
polarization.
26
Testing of fuses, light bulbs, etc. The CONT mode
Touch one of the fuse's terminals with one hand. Touch the other terminal with the measurement pin. If a
fuse, light bulb, etc. are in working order, Fazer will react.
