Checking For The Presence Of Ac Voltage - Ideal 61-657 Manual De Instrucciones

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 de-energized 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 61-647 may not detect the presence of voltage
in Tamper Resistant Outlets. The 61-657 should be placed in the low voltage
detection mode (blue LED) in order to sense the presence of voltage in Tamper
Resistant Outlets.
