Description
As a proud owner of the first wireless
Fieldpiece clamp meter, SC57, you are well on
your way to eliminating tangled wires. SC57 will
give you the power to receive measurements
wirelessly from anywhere on the jobsite. For
instance, you can transmit indoor wet bulb
measurements for target superheat over the air
while you work at the condenser.
Your SC57 can receive measurements
wirelessly from any Fieldpiece accessory head
connected to a Fieldpiece wireless transmitter
like an ET2W or EH4W. Your SC57 comes with
one ET2W wireless transmitter.
In addition, your SC57 can transmit wirelessly
any measurement range on the dial to Fieldpiece
wireless receivers; like EH4W, HG3, LT17AW, or
another SC57.
SC57 is a swivel clamp meter designed for
the HVAC/R technician. The swivel on the
SC57 allows you to see the amperage reading,
regardless of wire orientation. The jaw light

location on the jobsite. Like receiving an indoor
wet bulb temp. when your at the condensor.
Receiving Wireless Measurements
1. Select RECV switch position on SC57. Hold
SYNC button until meter beeps (>1 sec). Search
pattern initiates.
2. Connect and turn on any Fieldpiece accessory
head to the ET2W wireless transmitter.
3. Select DC switch position on ET2W for all acces-
sory heads except ACH4 (AC switch position).
4. Hold SYNC button on ET2W for one second.
5. The wireless measurement, signal strength,
and battery life of the ET2W will display in the
top-right corner of the SC57 screen.
Note: If the ET2W is not connected within 2 min,
the SC57 will beep and stop searching.
Wireless Transmitter Mode

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.

Maintenance
Clean the exterior with a dry cloth. Do not use
liquid.
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.

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)
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.
