• 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 better
control of the equipment in unexpected situations.
Equipment Use and Care
• Do not force equipment. Use the correct equipment for your application. The cor-
rect 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 unfa-
miliar with the equipment or these instructions to operate the equipment. Equip-
ment can be dangerous in the hands of untrained users.
• Maintain equipment. Check for missing parts, breakage of parts and any other condi-
tion 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 situ-
ation.
• Use only accessories that are recommended by the manufacturer for your equip-
ment. Accessories that may be suitable for one piece of equipment may become haz-
ardous 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 on ly identical
replacement parts. This will ensure that the safety of the tool is maintained.
Specific Safety Information
This section contains important safety information that is specific to this tool.
Read these precautions carefully before using the RIDGID® micro DM-100 Digital
Multimeter to reduce the risk of electrical shock or other serious injury.
Keep this manual with the tool for use by the operator.
Multimeter 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 exposed
metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body
isolated from ground using appropriate methods.
