Description
The SC460 is an essential clamp meter with
wireless functionality for the HVACR professional.
Receive wireless measurements from Fieldpiece
accessory heads and wireless transmitters from
anywhere on the jobsite. For instance, receive
an indoor delta T temperature measurement
wirelessly from a Fieldpiece transmitter while
you work at the condenser. Send your electrical
measurements to the Job Link™ mobile app via the
Fieldpiece JL2 Transmitter. (See Wireless section for
more details).
Hang your SC460 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, even in low light conditions
using the bright blue backlight.
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 connect with
Fieldpiece accessory heads.
The SC460 clamp meter is built to withstand the
rigors of HVACR eld work with high impact plastic
and a display you can read in very hot or very cold
environments.

Amps AC (AAC), Frequency (Hz) through the clamp and Inrush AAC
current is measured in the VAC/AAC/Hz switch position shown above.
Inrush AAC Current
Inrush mode captures the starting amp draw of a motor. Starting amp
draw can assist in diagnosing a motor before it fails.
Activate Inrush mode
1 Rotate selector switch to VAC/AAC/Hz.
2 Press SELECT once to show AAC on upper display. Press INRUSH on the
right side of meter to activate.
3 Clamp meter around the motor’s start wire. Turn motor on. The
starting amp draw will hold on the upper display.
4 Press INRUSH to reset the test. Press INRUSH for 2 seconds to exit
Inrush mode.
Inrush measurement period: 100-milliseconds
Minimum input: >2A on 100A range; >20A on 400A range
!
Note: AAC or Hz through the clamp and VAC through the test leads
can be measured simultaneously. However, if only AAC, Frequency
(Hz), or Inrush AAC is measured through the clamp, test leads and
thermocouples must be unplugged from the meter.

MicroAmps DC (µADC)
Microamps for ame rectier diode test on a heater control. Connect
leads between ame sensor probe and control module and turn heating
unit on to read µA measurement.When the ame is on, there should be a
measurable µADC signal, typically under 10µADC. Compare measurement

Capacitance (MFD)
Set to MFD to test motor start and run capacitors. Capacitors are one
of the most failure prone components in a HVACR system. Disconnect
from power and resistors between terminals. Discharge capacitor before
testing. If dIS.C is displayed, the capacitor needs to be fully discharged to
test. Press SELECT three times to enter Capacitance mode.

Resistance (Ω)
Used for“ohming out”a compressor. A 0.01Ω resolution is useful to
test the resistance between the terminal poles because the values are
typically very low. Resistance is default test in this switch position.

Temperature
Plug anyType K thermocouple directly into the meter to measure
temperature. Measure outdoor dry bulb temperature for target superheat
while at the condensor with theType K thermocouple input.
Cold junction is located inside the meter and allows for accurate
measurements even in rapidly changing ambient temperatures (going
from rooftop to freezer). No adapter is required.
By default, °F will show on top display and °C on bottom display.

*After eld calibration
Temperature Calibration
For accuracies of ±1°F, calibrate both
thermocouples to a known temperature. A glass
of stabilized ice water is very close to 32°F (0°C)
and is usually very convenient but any known
temperature can be used. Ideally you should
calibrate to a known temperature closest to the
temperatures you will be testing.
1. Rotate dial to the °F °C position.
2. Plug one thermocouple to be
calibrated into the Type K input.
3. Unscrew A and B and remove the
battery cover.
4. Stabilize a large cup of ice water.
Stir the ice with the water until
temperature stays at a stable value.
5. Immerse the thermocouple probe
and let it stabilize. Keep stirring
water to prevent thermocouple from
direct contact with ice.
6. Use a small screwdriver to adjust
calibrationTemp Cal pot below the
battery as close to 32°F(0°C) as you
would like.
Note: J1-J2 switch is for factory
calibration purposes only. Do not
switch from J2.
