SAFETY INFORMATION
The AC/DC clamp meter has been designed according to IEC1010 – 1 and
IEC1010 – 2 – 032 concerning safety requirements for electrical measuring
instruments and hand – held current clamps with an overvoltage category (CAT
II) and pollution 2.
SAFETY SYMBOLS
Important safety information, refer to the operating manual.
Dangerous voltage may be present.
Earth ground.
Double insulation (Protection class II).
The AC/DC clamp meter complies with the requirements of the following
European Community Directives: 89/336/EEC (Electromagnetic Compatibility)
and 73/23/EEC (Low Voltage) as amended by 93/68/EEC (CE Marking).
However, electrical noise or intense electromagnetic fields in the vicinity of the
equipment may disturb the measurement circuit. Measuring instruments will also
respond to unwanted signals that may be present within the measurement
circuit.
Users should exercise care and take appropriate precautions to avoid
misleading.
SAFETY PRECAUTIONS
Follow all safety and operating instructions to ensure maximum personal safety
during the operation and to ensure the meter is used safely and is kept in good
operating condition.
-1-
Read these operating instructions thoroughly and completely before
•
operating your meter. Pay particular attention to WARNINGS, which will
inform you of potentially dangerous procedures. The instructions in
these warnings must be followed.
Always inspect your meter and test leads for any sign of damage or
•
abnormality before every use. If any abnormal conditions exist (i.e.
broken test leads, cracked cases, display not reading, etc.), do not
attempt to take any measurements.
Do not expose the instrument to direct sunlight, extreme temperature or
•
moisture.
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 by using dry
clothing; rubber shoes, rubber mat, or any approved insulating material.
You always are careful when working with voltages above 60V dc or
•
30V ac rms. Keep fingers behind the probe barriers while measuring.
Never use the meter to measure voltages that might exceed the
•
maximum allowable input value of an y function.
Never touch exposed wiring, connections or any live circuit when
•
attempting to take measurements.
MAINTENANCE
Before opening the case, always disconnect test leads from all
•
energized circuits.
Never use the meter unless the back cover is in place and fastened
•
completely.
Do not use abrasives or solvents on the meter. To clean it using a damp
•
cloth and mild detergent only.
Qualified and trained service technicians should only perform calibration
•
and repair of the meter.
-2-
Do not attempt calibration or service unless trained and another
•
person capable of rendering first ai d and resuscitation is present.
GENERAL DESCRIPTION
