CATIII 600V, class II and pollution degree 2
indoor use comply with CE, RoHS compliant.
CATIII is for measurements performed in the
building installation.
Description
The new SC200 series compact clamp meters
are designed for everyday HVACR service. Their
compant pocketable design makes them easy
to take on any job.
Hang the SC260 to any metallic surface with
its newly designed swivel magnet to keep your
hands free to do more. Test variable frequency
drives more accurately with True RMS and easily
see your measurements in low lighting with the
bright blue blacklight (SC260 only).
Save time with the new Auto Select 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 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 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 circuit before turning
any inductor o, including motors, transform-
ers, 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.
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, r
efer to manual.

Functions
Temperature (°F/°C) SC240 and SC260 only
Plug any Type K 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.

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.
