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.

"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 conductio
n 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.

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.
