EPF 30 Professional Scanning Feature:
One problem for all single pole contact and non contact
devices is the FALSE LIVE indication of ‘floating’ (typically open
circuit) conductor(s) that are in the proximity of the true live
conductors. EPF 30 Professional uses Patented ‘True Phase
Locate’ memory scanning to eliminate false signals to give a
clear and positive indication of true live phase(s) found with a
continuous bright red LED and continuous tone.
The test button can be momentarily pressed at any time to
clear and reset the memory function (this feature helps to
‘focus’ on true live conductors if there are many open circuit
conductors in a cable bundle or terminal block).
To use the memory scanning feature momentarily press the
memory scanning button (to reset the memory) and
sequentially touch the tip to each conductor.
If the EPF 30 Professional still detects more than one live
signal repeat the test KEEPING THE TIP IN PLACE ON EACH
CONDUCTOR FOR A MINIMUM OF 2 SECONDS so the
memory can ‘lock’ the true signal until only true live
conductors are found.
Warning
By the law of chance you may contact the live cable first (or
you may choose to check what you assume is the live cable
first). Clearly the true phase locate memory function will then
eliminate all lower voltage cables WHICH MAY STILL BE
CARRYING VOLTAGES GREATER THAN 50V AC.
It is always good practice to hit the memory re-set button
and re-test any conductors or terminals BEFORE attempting
to handle or cut them AS EVEN INDUCED VOLTAGES CAN
BE DANGEROUS.
