Safety Information
!
Understand and follow operating instructions
carefully.
A Warning identifies conditions and procedures
that are dangerous to the user. A Caution identies
conditions and procedures that can cause damage to
the Product or the equipment under test.
WARNING
To avoid possible electric shock, personal injury or
death, follow these guidelines:
• Use the meter only as specied in this manual;
otherwise, the protection provided by the meter
may be impaired.
• Do not use if meter appears damaged. Visually
inspect the meter to ensure case is not cracked
and back case is securely in place.
• Inspect and replace leads if insulation is damaged,
metal is exposed, or probes are cracked. Pay
particular attention to the insulation surrounding
the connectors.
• Do not use meter if it operates abnormally as
protection maybe impaired.
• Use only correct measurement category (CAT),
voltage, and amperage rated probes, test leads,
and adapters for the measurement.
• Do not use this meter to verify the presence of
hazardous voltages on circuits that may have
voltages generated from frequencies above
1000Hz as the low pass filter limits voltage
measurements to below 1000Hz.
• Do not use during electrical storms or in wet
weather.
• Do not use around explosive gas, dust, or vapor.
• Do not apply more than the rated voltage to,
as marked on the meter, between terminals or
between any terminal and earth ground.
• Do not use without the battery and the back case
properly installed.
• Replace battery as soon as battery indicator
appears to avoid false readings.
• Remove the test leads from the circuit prior to
removing battery cover.
• Do not attempt to repair this unit as it has no
user-serviceable parts.
• Temperature switch prevents leaving
thermocouple plugged in while measuring
voltage.
• Do not measure current while the test leads are
in the input jacks.
• When measuring high frequency AC current,
do not exceed the rated 600AAC of the clamp.
Failure to adhere may cause the clamp to heat
up dangerously.
• Do not use the HOLD function to measure
unknown potentials. When HOLD is turned on,
the display does not change when a dierent
potential is measured.
• Do not use in CAT III or CAT IV environments
without the protective cap of test probe. The
protective cap decreases the exposed probe
metal <4mm. This decreases the possibility of arc
32
ash from short circuits.

!
• Do not place magnet inside Category IV panel.
Place it outside the panel instead.
• Always work with a partner.
• Keep ngers behind the nger guards on the
probes.
CAUTION
To protect yourself, think “Safety First”:
• Voltages exceeding 30VAC or 60VDC pose a shock
hazard so use caution.
• Use appropriate personal protective equipment
such as safety glasses, face shields, insulating
gloves, insulating boots, and/or insulating mats.
• Disconnect circuit power and discharge all highvoltage capacitors before testing resistance,
continuity, diodes, or capacitance.
Before each use:
• Perform a continuity test by touching the test
leads together to verify the functionality of the
battery and test leads.
• Use the 3 Point Safety Method. (1) Verify meter
operation by measuring a known voltage. (2)
Apply meter to circuit under test. (3) Return to
the known live voltage again to ensure proper
operation.
• Use the proper terminals, functions and range for
your measurements.
• Never ground yourself when taking electrical
measurements.
• Connect the black common lead to ground
or neutral before applying the red test lead to
potential voltage. Disconnect the red test lead
from the voltage rst.
All voltage tests: All voltage ranges will
withstand up to 1000VDC/750VAC rms. Do not
apply more than 1000VDC or 750VAC rms.

Caution, risk of electric shock

WARNINGS
DISCONNECT AND UNPLUG TEST LEADS before opening case.
TEST NCV FUNCTION ON KNOWN LIVE WIRE before using.
DO NOT APPLY VOLTAGE greater than 30VAC/VDC to the
thermocouple or the jacks when the rotary dial is on °F°C. (Use
only Type K thermocouples)
DO NOT APPLY VOLTAGE TO THE JACKS when the rotary dial is on
microamps. Even low voltages can cause a current overload and
potentially harm the meter.

Description
Your SC480 is the essential clamp meter with
wireless functionality for the HVACR professional.
Send your electrical measurements directly to the
Job Link® System mobile app. Leave the meter
behind a closed blower door and view the current
measurement on your mobile device.
Help determine system eciency by directly
measuring power consumption (W) of the system.
Use this value to inform your customer of energy
saving measures you can take to help them save
money on their energy bills.
The SC480 is great for troubleshooting minisplit systems. Reach those cramped mini-split
connectors with the included RCT2 probe tips
for voltage and resistance measurements. Plus,
measure frequency (Hz) directly with clamp jaw.
Hang your SC480 clamp meter to any metallic
surface with the heavy-duty magnet. See both
voltage and amperage readings at the same time
on the big dual display.
Verify the order of 3-phase voltage lines with
just two leads. Capture L1L2 and L1L3 to check
that motor lines are correctly installed with Phase
Rotation test.
Take more accurate VAC and AAC readings on
variable frequency drives with True RMS sensing
technology. Measure the starting amp draw of a
compressor with Inrush current mode.
Illuminate the way with a powerful LED built into
the clamp jaw. Easily see your measurements with
the bright blue backlight on the display.
Take measurements more safely with one hand
using the single test lead holder. Test leads come
with removable gold plated tips to reliably connect
Fieldpiece accessory heads.
