Description
Your SC54 is a swivel clamp meter specially
designed for the HVACR technician. The swivel
on the SC54 allows you to get a good viewing
angle on the display while taking amperage
readings through the clamp, regardless of the
wire orientation. The SC54 has the functions
you want as an HVACR technician.
Get fast manual ranging performance on an
easy to use auto-ranging clamp meter.
The SC54 is compatible with Fieldpiece
accessory heads allowing you to measure many
parameters on the SC54 display.

makes it easier
to use in any lighting condition.True RMS helps
you take more accurate voltage and amperage
readings on variable frequency drives.
The unique temperature circuit allows the
SC54 to get accurate temperature readings
faster when moving from a rooftop to a freezer.
The easily accessible field calibration allows
you to calibrate the temperature on your SC54
without hassle.

Non Contact Voltage (NCV)
Use the non contact voltage (NCV) feature to test if a wire is hot
or not. Always test on a known live source before using. A red LED
blinks and beeping sound is emitted at voltages >24VAC
AC Voltage Detection Range: 24VAC to 600VAC (50-60Hz)
Temperature (°F/°C)
Plug any K-type thermocouple directly into the meter to measure
temperature. Cold junction is located inside the meter and allows for
extremely accurate measurements even in rapidly changing ambient
temperatures (going from rooftop to freezer). No adapter is required.
See Temp Calibration section for calibration instructions.

±(2%+6°F) 750°F to 2200°F, ±(2%+3°C) 400°C to 1200°C
Sensor type: K-type thermocouple
Overload protection: 30 VDC or 30VAC rms
Temp. Calibration
For accuracies of ±1°F,
calibrate 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.
1. Select the °F/ °C range.
2. Plug thermocouple to be
calibrated into the K-type jack.
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
32°F (0°C).
5. Immerse the thermocouple
probe and let it stabilize. Keep
stirring to prevent micro-
environments.
6. Use a small screwdriver to
adjust calibration pot C to the
right of the battery as close to
32°F as you would like.
Modular
Expandability
Your Swivel Clamp Meter is compatible with
all Fieldpiece Accessory Heads. With Fieldpiece
Accessory Heads, you can measure any
available parameter, and read the measurement
on your meter's display in real-time.
Just set the range to mVDC. Pressing SEL
changes the mV range. Remove the probe tips
of your test leads, and connect your accessory
head (model AAV3 shown).
Visit www.eldpiece.com to see all of the
dierent accessory heads that Fieldpiece oers.
Safety Features

voltages above 30V.
2. Switchto theNCV function (non contact volt-
age)and point clamp clawtowardssuspected
voltage source. Monitor the bright LED and
beeper to see if the source is“hot.”
3. Rotate the clamp to the angle that best suits
the situation.
4. Tempswitchtopreventleavingthermocouple
plugged in while measuring voltage.
BatteryReplacement
The battery must be replaced when the
battery icon is empty. "bAtt" will display with a
beeping sound. Meter will shut o in 5 seconds.
Disconnect and unplug leads, turn meter o
and remove battery cover.
Safety Information
• Never ground yourself when taking electrical
measurements. Do not touch exposed metal
pipes, outlets, xtures, etc., which might be at
groundpotential,while taking measurements.
Keep your body isolated from ground by us-
ing dry clothing, rubber shoes, rubber mats,
or any approved insulating material.
• Disconnect the test leads before opening the
case. Inspect the test leads for damage to the
insulationor exposed wire. Replaceifsuspect.
Keepyourngers behind the nger guardson
the probes while taking measurements.
• When disconnecting from a circuit, disconnect
the“RED”leadrst,thenthecommon“BLACK”
lead. Use one handed testing when possible.
Work with others.
• Turn o power to the circuit under test before
cutting, unsoldering, or breaking the circuit.
• Do not measure resistance (ohms) when cir-
cuitis powered.Isolate load by disconnecting
from circuit.
• Disconnect the meter from the circuit before
turning any inductor o, including motors,
transformers, and solenoids. High voltage
transients can damage the meter beyond
repair. Do not use during electrical storms.
• Do not apply more than rated voltages be-
tween input and ground.
• Isolate capacitors from system and discharge
them safely before testing.
All voltage tests: All voltage ranges will
withstand up to 600V. Do not apply more than
600VDC or AC rms.

Caution, risk of electric shock
Caution, refer to manual.

Maintenance
Clean the exterior with a dry cloth. Do not
use liquid.
Limited Warranty
This meter is warranted against defects in

WARNINGS
DISCONNECT AND UNPLUGTEST LEADS before opening case.
TEST NCV FUNCTION ON KNOWN LIVE WIRE before using.
DO NOT APPLY VOLTAGE greater than 30VAC or 60VDC to the
thermocouple or the jacks when the rotary dial is on °F. (Use
only k-type thermocouples)
REMOVE THETHERMOCOUPLE when taking voltage measurements.
DISCONNECT TEST LEADS when measuring temperature.
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.
