INSTRUCTION FOR USE
●
Before using the Phase Comparator, clean the Front End (Fiber
Glass) with a polymer polishing.
●
All models do not require batteries and are being signal driven
(current taken from the source or circuit under test) and do not
require arming. However,
it is recommended that a functional
test be carried out using a High Voltage Insulation tester
or a
proving unit.
●
To prove the Phase Comparator, set the voltage on the Proving
unit or on the High Voltage Insulation tester, to suit the model of
Phase Comparator. Turn the test "ON" or the proving unit "ON".
The Neon should light up (if the voltage if high enough) and the
indicator should move nearest the voltage measured.
●
Reverse the poles of the Phase Comparator and check that an
out-of-phase indication is given.
●
They are
no user serviceable parts
on our range of Phase
Comparators. Should the Phase Comparator become damaged,
faulty or, suspect in any form, please consult with your nearest
distributor to return it to the factory.
●
There must be galvanic contact between the test electrodes and
the part of the installation under test and, no other part of the
phase Comparator, except the electrodes, should be in contact
with energized or earthed parts, in order to ensure accuracy of
the display.
