Safety Information
Never ground yourself when taking electrical
measurements. Do not touch exposed metal
pipes, outlets, fixtures, etc., which might be
at ground potential, while taking measure-
ments. 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 fingers behind the finger guards
on the probes while taking measurements.
When disconnecting from a circuit, disconnect
the "RED" lead first, then the common "BLACK"
lead. Use one handed testing when possible.
Work with others.
Turn off 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 circuit before turning
any inductor off, including motors, transform-
ers, and solenoids. High voltage transients
can damage the meter beyond repair.

Quick Start
1. For electrical testing, connect test leads to
"COM" and "+" jacks.
2. Rotate the dial to your desired measurement.
3. Connect to test points and read measurement.
4. For temperature testing, remove test leads,
slide TEMP switch to the right and connect
Type K thermocouple.

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.
Temperature switch prevents leaving thermo-
couple plugged in while measuring voltage.
When measuring high frequency AC current, do
not exceed the rated 400AAC of the clamp.
Failure to adhere may cause the clamp to heat
up dangerously.
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.

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°C. (Use
only Type K 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.

Description
The SC600 series are the new loaded clamp
meters for the HVACR professional. Hang your
SC600 series clamp meter to any metallic surface
with the redesigned heavy-duty magnet and
conveniently store your test leads when the
job is done. See both voltage and amperage
readings at the same time on the big dual LCD
display, even in low light conditions using the
bright blue backlight (backlight SC640 only).
Easily see your amperage readings no matter
how you clamp around a wire with the swivel
head AAC clamp.
Take more accurate VAC and AAC readings on
variable frequency drives with True RMS sensing
NCV
technology (SC640 only). Measure the starting
MFD
amp draw of a compressor with Inrush current
feature (SC640 only). Use the clamp jaw light to
easily light up the test area. (SC640 only).
Take measurements with one hand using the
NCV
Range
single test lead holder for added safety. Test
MFD
leads come with removable gold plated tips to
connect with Fieldpiece accessory heads.
The SC600 series clamp meters are built to
withstand the rigors of HVACR with high impact
plastic and a display you can read in very hot or

and RED LED will display the presence of voltage. Audible beep increases
from intermittent to continuous as intensity of field (EF) increases.
