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 and backlight lighting condition. True RMS helps you take more accurate voltage readings on variable speed drives.

Functions

Wireless Receiver Mode

Use your SC57 to wirelessly receive a live measurement you have set up at a diffeent 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,

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. Ground 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.

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.

Maintenance

Clean the exterior with a dry cloth. Do not

use liquid.
