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.

The bright blue backlight
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.

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.

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).

Safety Features

1. Bright LED and beeper warn you when testing
voltages above 30V.

2. Switch to the NCV function (non contact volt­age) and point clamp claw towards suspected
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. Temp switch to prevent leaving thermocouple
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
ground potential, while taking measurements.
Keep your body isolated from ground by us­ing 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
insulation or exposed wire. Replace if suspect.
Keep your ngers behind the nger guards on
the probes while taking measurements.

• When disconnecting from a circuit, disconnect

the “RED” lead rst, then the common “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 cir­cuit is 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 be­tween 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.

Symbols used:
Caution, risk of electric shock
Caution, refer to manual.

Double insulation

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 or 60VDC to the

thermocouple or the jacks when the rotary dial is on °F. (Use

only k-type thermocouples)
REMOVE THE THERMOCOUPLE 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.

Maintenance

Clean the exterior with a dry cloth. Do not

use liquid.
