Detection of live wires in the DETECTION mode
This application allows to detect alternating voltage (50Hz/220V) in place, where direct access to a
metal conductor is impossible. Set the detection sensitivity level close to its maximum position but
without forcing the device to react. Press the DETECTION button. Move the measurement pin close to
the location, where a hidden live wire may run. If Fazer detects voltage you should - by lowering the
sensitivity - try to pinpoint exact location of the live wire. Mind the materials that screen the field.
Non-contact PHASE detection in wires in the DETECTION mode
Set the detection sensitivity (Fazer's bottom side) almost to the max. Press the DETECTION button and move
the measurement pin close to a tested wire. If the wire (or a device) is connected to 220V, Fazer will react at
a distance of approx. 0.5m. By lowering the sensitivity level you can precisely determine, which wire is a
"phase" wire. By moving the measurement pin alongside the wire you can detect a rupture in a phase wire. If
the second wire is not connected to "zero", Fazer will indicate induced voltage.
Detection of harmful radiation in the DETECTION mode
Fazer reacts to harmful discharges that take place near monitor screens. Small electrical discharges cause
short disruptions to the Fazer's operations that manifest itself by cracking sounds and flickering LED light.
You can test this behaviour by placing the device close to a screen and switching the monitor on and off. In
case of a continued operation of a good monitor Fazer's cracking sounds will stop 20 cm from the screen at a
low detection sensitivity level.
Repairing Christmas tree lights in the DETECTION mode
The description of this application applies to Christmas tree lights with two wires. Connect the lights to a 220V
outlet. Separate wires at the socket to prevent them from influencing each other during the testing. With Fazer
in the DETECTION mode locate the first light from the plug connected to the "phase" wire by acting as in:
"non-contact phase detection in wires". If the light is working Fazer will react before and after the light. In
case of lights with more circuits you should take out the first lights from the phase side of not tested circuits.
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.
