Introduction
The IDEAL 61-637 and 61-627 Single Range Non-Contact Voltage Testers
automatically detect and indicate the presence of voltage within specified ranges.
The 61-637 detects voltage within a range of 24-600V AC and the 61-627 detects
voltage within a range of 50-600V AC. Both testers provide non-contact detection
of voltage through an antenna enclosed in plastic at the tip of the tester which
senses the presence of the electromagnetic field present around live conductors.
The 61-637 has a flash light that works independently of the testing function and is
activated by an independent On/Off button.
Arc Flash and Shock Hazard, Proper PPE Required. Follow all safety procedures,
wear proper PPE in accordance to NFPA 70E. Read and fully understand the
instruction manual prior to using this product. Failure to comply can result in
serious injury or death.

WARNING
Arc Flash and Shock Hazard, Proper PPE Required. Follow all safety procedures,
wear proper PPE in accordance to NFPA 70E and follow the guidelines below and
the instructions in this manual when operating the tester. Failure to comply can
result in serious injury or death.
• Choking Hazard, Small Parts. Keep Away from Children Sharp Objects
Hazard, This is not a toy. It is not for use or play by children. Keep
Away from Children. Failure to do so can result in serious injury.
• Only experienced or technically competent consumers should use this
equipment. When in doubt, call an experienced electrician to make any and
all necessary repairs or installations. At all times, perform any necessary
work on a de-energized circuit that has had its circuit breaker turned off and
has been locked out.
• Use the Tester only as specified in this manual or protection provided by the
Tester can be compromised.
• Before using the Tester, visually inspect it to ensure the case or tip are not
cracked and the battery cap is securely in place. Do not use if the Tester
appears damaged.
• When using the tester, keep fingers behind the tactile barrier at the base of
the tester. (see #4 on page 9)
• This Tester is intended for use by qualified electricians and competent
consumers. Follow NFPA 70E Standards for Electrical Safety when using
this Tester.
• Do not use without the batteries correctly in place and the slide on battery
cover secured.

WARNING
Arc Flash and Shock Hazard, Proper PPE Required. Follow all safety procedures,
wear proper PPE in accordance to NFPA 70E and follow the guidelines below and
the instructions in this manual when operating the tester. Failure to comply can
result in serious injury or death.
• Have the Tester serviced only by qualified service personnel.
• Do not use the Tester around explosive gas, dust, or vapor, or during electrical
storms, or in wet environments.
• Do not apply more than the rated voltage, as marked on the Tester. Observe
CAT Rating of Tester when in use.
• To avoid false readings that can lead to electrical shock and injury, replace the
batteries as soon as the low battery indication appears.
• Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution.
• Do not work alone so that assistance can be rendered in an emergency.
Use extreme caution when working around bare conductors or bus bars.
•
Contact with the conductor could result in electric shock.
• Adhere to local and national safety codes. Individual protective equipment
must be used to prevent shock and arc blast injury where hazardous live
conductors are exposed.
• Cancer and Reproductive Harm
CAUTION
Tester damage can occur if the following guidelines are not adhered to.
• Use the proper settings and voltage ratings for the measurement application.
• Clean the case and accessories with a damp cloth and mild detergents only.
Do not use abrasives or solvents. Make sure the tester is completely dry
before use.
• Not intended for insertion into electrical outlet slots.
• Do not apply excessive side or torsional loading to the sensing tip as
damage may occur.

Operating Features
Audible Notification Disable (61-637 Only)
The tester can be operated with a visual only indication of voltage when working in
noise sensitive/noise restricted areas. With the tester On, press the Speaker button
for less than 1s. The tester will beep once to indicate the audible warning is muted
and only a visual indication will be provided. To restore the audible warning, press
the speaker button for less than 1s. The tester will beep twice to indicate the audible
warning is active and both a visual and audible indication will be provided. The
tester is set to Audible Notification On as the default setting.
Flashlight (61-637 Only)
An LED Flashlight in the tip operates independently of the tester functions and can
be used to illuminate the work area. Press the Flashlight Button to turn it On/Off.
The tester is set to Flashlight Off. The Flashlight will Auto Power Off after 5 minutes
of no voltage detection. Further voltage detection will reset the APO function to 5
minutes again.
Note: Use of the flashlight will decrease battery life.
Auto Power Off
After 10 minutes of inactivity (no button pressed and no signals detected), the
tester will emit one long beep (~0.5s) and then shut off. Note: if the flashlight is on,
it will be also shut off.
Low Battery Indication
If battery voltage is less than around 2.4V, the green led in the tip will flash 3 times
and the buzzer will send out one long beep, then turn off the device.
10
Tester Operation
Turning The Tester On
Press the Power On/Off button for less than 1s to turn the tester On. The tester
will beep twice, and will light a steady Green LED in the tip of the tester to indicate
Power On.
Steady Green LED in the tip
indicates power-on
Turning The Tester Off
Press the Power On/Off button for more than 1s to turn the tester Off. Listen for a
long steady beep (~.5s) and watch for LED in the tip to turn off. The tester is now
deactivated and is not operational.
11
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.
