UK - Operating instructions
Thank you for purchasing an OEHLBACH
®
quality product.
General
The OEHLBACH® Phaser phase-tester (Part #17017) is intended for the rapid and simple
detection of the phase-proper polarity of audio and video components. If you connect a
number of hi-fi, video or home cinema devices to a multiple outlet strip without taking ac-
count of their phase, the earth potential equalising currents cause perceptible interference.
This cannot happen if you connect correctly to a phase-identified mains strip (such as
the Oehlbach XXL® Powersocket 808 / OEHLBACH® Powersocket 404) and you will be
rewarded with the best picture and sound quality.
Inserting the battery
Use the included Allen key® to open the side of the device which is labeled „Ground“
4
.
Now connect the 9V battery supplied to the terminals provided and stow the battery away
inside the tester. Avoid mechanical stress when closing the side cover. The device is now
ready for use. We recommend that you remove the battery if you will not be using the
tester for some time.
Battery charge indicator LED
The yellow „Batt. low“ LED
lights up as battery capacity begins to fade. Please replace
the 9V battery if this occurs, otherwise perfect operation of the device can not be guaran-
teed.
Determining the phase of your devices using the polarity tester
Power “OFF” the main switch of the device you want to determine the phase difference.
Disconnect the device from the main power. Disconnect all other connections to other de-
vices (Cinch, aerial cable etc.) Connect the device on the Oehlbach® PHASER and switch
„ON” the main power switch. This procedure protects the Phaser from damage by possible
surge. Press and hold the „Test“-button
1
on the PHASER. One of the two red LEDs
will now light up while holding the button and will indicate the phase on the connected
device. You can now remove the device plug from the phase tester, turn it 180° and plug it
in again. The other red LED
should now light up while holding the Test
1
button. The
phase of the device has now been detected.
Devices with “Euro-Plug” do not have connection to PE Line „protective earth“. To detect
phasing of those devices, it will be necessary to connect the „Ground“
4
connector of the
Phaser to any ground connector of the device (metal part of the device’s housing or ground
connector of an RCA socket) by using the ground-wire included.
Comments about the measurement: If the same LED
lights up even after having turned
the plug 180°, the Phaser cannot determine the correct Phase. This might happen with
devices with low received power. This is no malfunction of the Phaser.
Note: Some manufacturer of hardware devices mark phasing of their devices. Since the
Phaser involves the complete device including it’s powercord into ist measuring as well,
phase-detection may vary to already factory-marked phasing of your hardware.
Environmental note
Batteries - even heavy metal-free batteries - must not be disposed in household waste.
Exhausted batteries must be disposed in the old battery bins in shops or at public disposal
site.
