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 (SC240/SC260 only).

02
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.

Caution, risk of electric shock

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.
