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

to manufacturer’s specication to determine if replacement is necessary.

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.
