2. Safety

SAFETY NOTES

This user manual contains information and warnings that must be followed for operating the

instrument safely and maintaining the instrument in a safe operating condition. If the instrument is

used in a manner not specified by the manufacturer, the protection provided by the instrument

may be impaired.

The meter protection rating, against the users, is double insulation per UL/IEC/EN61010-1 Ed. 3.0,

IEC/EN61010-2-033 Ed. 1.0, CAN/CSA C22.2 No. 61010-1 Ed. 3.0, IEC/EN61010-2-032 Ed. 3.0 &

IEC/EN61010-031 Ed. 1.1: Measurement Category III 600V & Category IV 300V AC & DC.

BRIEF INFORMATION ABOUT MEASUREMENT CATEGORIES

Measurement Category IV is applicable to test and measuring circuits connected at the source of the building’s

low-voltage MAINS installation. Examples are measurements on devices installed before the main fuse or

circuit breaker in the building installation.

Measurement Category III is applicable to test and measuring circuits connected to the distribution part of the

building’s low-voltage MAINS installation. Examples are measurements on distribution boards (including

secondary meters), circuit-breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets

in the fixed installation, and equipment for industrial use and some other equipment such as stationary motors

with permanent connection to the fixed installation.

Measurement Category II is applicable to test and measuring circuits connected directly to utilization points

(socket outlets and similar points) of the low-voltage MAINS installation. Examples are measurements on

MAINS CIRCUITS of household appliances, portable tools and similar equipment.

TERMS USED IN THIS MANUAL

WARNING Identifies conditions and actions that could result in serious injury or even death

to the user.

CAUTION Identifies conditions and actions that could cause damage or malfunction in the

instrument.

WARNING STATEMENTS

To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. The

meter is intended only for indoor use.

To avoid electrical shock hazard, observe the proper safety precautions when working with

voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential shock hazard to the

user. Before and after hazardous voltage measurements, test the voltage function on a known

source such as line voltage to determine proper meter functioning.

Keep hands/fingers behind the hand/finger barriers (of the meter and the test leads) during

measurement. Inspect test leads, connectors, and probes for damaged insulation or exposed metal

FLIR CM4x USER MANUAL Document ID: CM4x-en-US_AA

before using the instrument. If any defects are found, replace them immediately. Use only the test

leads provided with the equipment (or UL Listed Probe Assemblies rated CAT III 600V or better).

The accompanied test probe assembly meets UL/IEC/EN61010-031 Ed. 1.1 to the same meter

ratings or better. IEC 61010-031 requires exposed conductive test probe tips to be ≤4mm for CAT

III & CAT IV ratings. Refer to the category markings on your probe assemblies as well as on the add-

on accessories (detachable Caps or Alligator Clips, etc.), if any, for applicable rating changes.

This Clamp meter is designed to be clamped around or removed from un-insulated, hazardous live

conductors. Nonetheless, individual protective equipment must be used when hazardous live parts

in the installation, where the measurement is to be carried out, could be accessible.

Remove test leads from meter before taking clamp measurements.

CAUTION STATEMENTS

Disconnect the test leads from the test points before changing meter functions.

Disconnect the test leads from the meter before taking clamp measurements.

Do not use the device for a procedure that it is not intended for. This can cause damage to the

protection built into the instrument.

UL listing is not an indication or a verification of the accuracy of the meter
