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 meter. Failure to comply can
result in serious injury or death.
• Have the Meter serviced only by qualified service personnel.
• Do not use the Meter around explosive gas, dust, or vapor, or during electrical
storms, or in wet environments.
• When measuring, keep fingers behind the Tactile Barrier. See “The Meter” on
pg. 8 and 9.
• Do not apply more than the rated voltage, as marked on the Meter, between the
terminals or between any terminal and earth ground.
• To avoid false readings that can lead to electrical shock and injury, replace the
batteries as soon as the low battery indicator ( ) appears.
• Remove the test leads from the circuit prior to removing the battery door.
• Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution.
• Always ensure that test leads are secured so that they cannot be accidentally
snagged or tripped over.
• 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.
• Disconnect circuit power and discharge all high-voltage capacitors before you
measure resistance, continuity, or capacitance.
•
Never operate the Meter with the back cover removed or the case open.
o Cancer and Reproductive Harm
CAUTION
Meter damage, equipment under test damage or data loss can occur
if the following guidelines are not adhered to.
• Use the proper terminals, function, and range 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 meter is completely dry
before use.

Operating Features
High Voltage Warning (HI-V)
The meter beeps once (for 1 second) and a red LED illuminates and remains on as
long as the voltage remains above 30V AC or DC, or when the meter’s voltage range
is exceeded.
NOTE: This feature does not work in the Ohm or continuity modes. For ACV and
DCV, when voltages in excess of 30V is measured or the measured voltage is over
limit, then the high voltage alarm ‘ .’ appears on the screen display,
simultaneously the LED remains RED and beeping lasts for 1 second then silent
during measurement.
Data Hold Feature
Press the Hold button to toggle in and out of the data hold mode. “H” appears in the
upper left of the meter display when data hold is active. Use the data hold feature to
lock a measurement reading on the display. Press the Hold button again to unlock
the display and obtain a real-time reading.
Auto Power Off (APO) Feature Disable
The meter automatically powers itself down after about 30 minutes of no use. Press
any button, and the meter will wake up and enter the default function of that setting
before power down. To Disable APO, press and hold the HOLD button while turning
the dial to any desired function. When APO is defeated, the “APO” will be removed
from the display. Turning the meter off and back on will restore the APO default.

Backlight
Backlight is selectable
to be on in all
functions.
Press the BACKLIGHT button on the meter to turn the backlight on and off. The
white backlight will remain lit for about 5 minutes before it automatically turns off
to conserve battery power. Or turn the backlight off by pressing the button again.

Using Test Leads
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 meter with TL-757 Test Leads or equivalent. Test Leads must be rated for the
electrical environment the meter is being used in and have a voltage rating of at
least the voltage of the circuit to be measured. 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. Failure to do so can result in serious injury or death.
• Use only approved test leads. Do not use improvised connections that could
present a safety hazard.
• Ensure that the test leads are inserted into the correct input jacks when
measuring AC or DC current.
• Prior to using the test leads, inspect them carefully for damaged insulation,
exposed metal or bent probes. Check test leads for continuity. Do not use
leads if they appear damaged.
• When using the probes, keep fingers behind the guard rings on the probes.
• Connect the common test lead before connecting the live test lead. When
disconnecting test leads, disconnect the live test lead first.
• Always ensure that test leads are secured so that they cannot be accidentally
snagged or tripped over.
Protective Cap Guard Ring
Note: The 61-327 is only rated to 600V AC or DC MAX
WARNING: Arc Flash and Shock Hazard, Proper PPE Required.
Follow all safety procedures, wear proper PPE in accordance to NFPA 70E and
assure that the Protective Caps are in place when operating a properly rated
electrical meter/tester using the TL-757 Test Leads in a CAT IV 600V or CAT III
1000V environment.
This meter is intended for use with the IDEAL TL-757 lead set (provided with this
product) or equivalent. The lead set must comply with requirements for Overvoltage
and Measurement Categories CAT IV 600V CAT III 1000V.
This meter is CAT III 600V ONLY

Meter Operation
Non-Contact Voltage Sensing
First, rotate the function key to the NCV position. Place the sensing point marked
with NCV close to an AC outlet (or any AC conductor such as light switches or
power cords) and scan back and forth across the outlet. The meter beeps On/Off
continuously and the Red NCV LED above the display flashes if the sensing antenna
detects live voltage greater than 40V AC (50 -60 Hz). Voltages with frequencies
higher than 60Hz or electrostatic charges may also be detected by the NCV sensing
antenna. To differentiate between hot and neutral in an outlet, place the NCV tab
directly next to each slot in the outlet. The tone (buzzer) will sound over the slot
that is energized and not on the neutral slot. Either test lead can also be used to
differentiate between the hot and neutral. Plug the red or black test lead into the
V input jack on the meter. With the function switch in the NCV position, insert the
probe end of just one probe into the slots on the outlet. The meter will beep and the
Red LED will flash when a hot conductor is contacted.
NOTE: 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.

Verifying Continuity ( )
• Verify the circuit is de-energized.
• The meter will sense the level of resistance and beep if the resistance is less
than 10 Ω’s to confirm that continuity is present.
• The red LED will illuminate and the resistance value will be displayed.

Maintenance and Service
Equipment Maintenance and Service
Meter Inspection
Do not use if meter appears damaged. Visually inspect the meter to ensure the case
is not cracked.
Test Lead Inspection
Inspect and replace test leads if insulation is damaged, metal is exposed, or probes
are cracked. Pay particular attention to the insulation surrounding the connectors.
Battery Inspection/Replacement
Inspect the battery compartment monthly for any signs of degradation. Low battery
voltages will cause inaccuracies in readings. Remove the batteries for storage
or if the meter will not be used for longer than one month. Battery leakage will
compromise the safety of the meter and cause irreparable damage to internal
components.
Shock Hazard. Remove the test leads from the circuit prior to removing the battery
cover. Failure to comply can result in serious injury or death.
Maintenance and Storage
Switch off and disconnect the meter completely before carrying out any
maintenance. Clean the case with a damp cloth and mild detergent. Do not use
abrasives or solvents. Keep away from liquids and ensure the meter is completely
dry before use.
Service and Replacement Parts
This unit has no user-serviceable parts.
