Checking For The Presence Of Ac Voltage - IDEAL 61-637 Manuel D'utilisation Et De Sécurité

Checking for The Presence of AC Voltage

Prior to use, test on known live circuit to verify tester functionality. Place tip of the
tester near an AC voltage source and refer to the NCV Sensing Indications Table for
tester indication during operation.
Flashing Red LED in the tip and
intermittent beeping indicate
voltage is present. (See NCV
Sensing Indications table for
indications associated with each
range and mode setting)
While the NCV is a helpful function, it is ALWAYS RECOMMENDED that the
operator verify that any electrical conductor is completely deenergized and that
no voltage is present by measuring for voltage AND CONFIRMING THAT NO
VOLTAGE IS PRESENT and that all applicable PPE and lock out tag out procedures
be followed before attempting any work on ANY electrical distribution system.
Voltages with frequencies higher than 60Hz or electrostatic charges may also be
detected by the NCV sensing antenna. Due to the variability of designs across
device manufactures the 61-627 and 61-637 may not detect the presence of voltage
in Tamper Resistant Outlets.
