General Safety Rules
WARNING
Read all safety warnings and instructions. Failure to follow the warnings and in-
structions may result in electric shock, fire and/or serious injury.
SAVE THESE INSTRUCTIONS!
Work Area Safety
•Keep your work area clean and well lit. Cluttered or dark areas invite accidents.
•Do not operate equipment in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Equipment can create sparks which may ignite
the dust or fumes.
•Keep children and by-standers away while operating equipment. Distractions can
cause you to lose control.
Electrical Safety
•Avoid body contact with earthed or grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electrical shock if your body
is earthed or grounded.
•Do not expose equipment to rain or wet conditions. Water entering equipment will
increase the risk of electrical shock.
Personal Safety
•Stay alert, watch what you are doing and use common sense when operating
equipment. Do not use equipment while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating equipment
may result in serious personal injury.
Safety Symbols
In this operator’s manual and on the product, safety symbols and signal words are used
to communicate important safety information. This section is provided to improve un-
derstanding of these signal words and symbols.
This is the safety alert symbol. It is used to alert you to potential personal injury
hazards. Obey all safety messages that follow this symbol to avoid possible injury
or death.
DANGER indicates a hazardous situation which, if not avoided, will re-
sult in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION indicates a hazardous situation which, if not avoided, could
result in minor or moderate injury.
NOTICE indicates information that relates to the protection of property.
This symbol means read the operator’s manual carefully before using the equip-
ment. The operator’s manual contains important information on the safe and
proper operation of the equipment.

•Use personal protective equipment. Always wear eye protection. Protective equip-
ment such as as protective gloves and clothing, dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate conditions will reduce personal injuries.
•Do not overreach. Keep proper footing and balance at all times. This enables bet-
ter control of the equipment in unexpected situations.
Equipment Use and Care
•Do not force equipment. Use the correct equipment for your application. The
correct equipment will do the job better and safer at the rate for which it is designed.
•Do not use equipment if the switch does not turn it ON and OFF. Any tool that can-
not be controlled with the switch is dangerous and must be repaired.
•Store idle equipment out of the reach of children and do not allow persons un-
familiar with the equipment or these instructions to operate the equipment.
Equipment can be dangerous in the hands of untrained users.
•Maintain equipment. Check for missing parts, breakage of parts and any other con-
dition that may affect the equipment’s operation. If damaged, have the equipment re-
paired before use. Many accidents are caused by poorly maintained equipment.
•Use the equipment and accessories in accordance with these instructions, tak-
ing into account the working conditions and the work to be performed. Use of
the equipment for operations different from those intended could result in a hazardous
situation.
•Use only accessories that are recommended by the manufacturer for your
equipment. Accessories that may be suitable for one piece of equipment may be-
come hazardous when used with other equipment.
•Keep handles dry and clean; free from oil and grease. Allows for better control of
the equipment.
Service
•Have your equipment serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the tool is maintained.
Specific Safety Information
WARNING
This section contains important safety information that is specific to this tool.
Read these precautions carefully before using the RIDGID®micro CM-100 Digital
Clamp Meter to reduce the risk of electrical shock or other serious injury.
SAVE THESE INSTRUCTIONS!
Keep this manual with the tool for use by the operator.
Digital Clamp Meter Safety
•Use caution when working with voltages above 30 V AC RMS, 42 V AC peak or 60
V DC. These voltages pose serious shock hazard. High-voltage circuits, both DC and
AC, are very dangerous and should be measured with great care.Avoid working alone.
•Do not connect to voltages that exceed 600 VAC or VDC relative to earth ground.
This may damage the meter and expose the operator to a shock hazard.
•When using the probes, keep your fingers behind the finger guards on the
probes. This reduces the risk of electric shock.
•Never ground yourself when taking electrical measurements. Do not touch ex-

posed metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your
body isolated from ground using appropriate methods.
•Disconnect the test leads from the meter before making current clamp meas-
urements. This reduces the risk of electric shock.
•When measuring resistance, disconnect all power (remove batteries, unplug
cord, discharge all capacitors, etc.) to the circuit being measured. This reduces
the risk of electric shock.
•After resistance test, the capacitive circuits must be discharged. This will help
protect against electric shock.
•Use extreme caution when working near bare conductors and bus bars. Acci-
dental contact with conductors could result in electrical shock.
•Turn OFF power to the circuit under test before cutting, unsoldering, or break-
ing the circuit. Small amount of current can expose the operator to a shock hazard.
The EC Declaration of Conformity (890-011-320.10) will accompany this manual as a
separate booklet when required.

On Product Icons
This equipment is used to make electrical measurements. Incorrect use or im-
proper application may result in incorrect or inaccurate measurements. Selection of ap-
propriate measurement methods for the conditions is the responsibility of the user.
FCC Statement
This equipment has been tested and found to comply with the limits for a Class B digi-
tal device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not in-
stalled and used in accordance with the instructions, may cause harmful interference to
radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Consult the dealer or an experienced radio/TV technician for help.
Electromagnetic Compatibility (EMC)
The term electromagnetic compatibility is taken to mean the capability of the product to
function smoothly in an environment where electromagnetic radiation and electrostatic
discharges are present and without causing electromagnetic interference to other equip-
ment.
The RIDGID micro CM-100 Digital Clamp Meter conforms to all applicable
EMC standards. However, the possibility of it causing interference in other devices can-
not be precluded.
Changing/Installing Batteries
The RIDGID micro CM-100 Digital Clamp Meter is supplied without the battery installed.
When the low battery [ ] icon appears on the display screen, replace the battery. Op-
erating the clamp meter with a low battery can cause incorrect readings. Remove the bat-
tery prior to long-term storage to avoid battery leakage.
1. Switch OFF the device and disconnect test leads.
